Notes & Corrections

Noah's plant schedule identifies each plant by common name. The botanical column on the schedule uses informal references; full cultivar names below are for ordering, communicating with installers, or researching cultivation details.

Botanical Names for Ordering

Non-native plants on the plan

  • Crape Myrtle 'Colorama Scarlet' (1) — Asian, kept for ornamental value. No equivalent native substitute with same flower color.
  • Vernonia 'Iron Butterfly' (11) — AR/OK native, not VA. Still excellent for pollinators. If purist-native matters, swap for Vernonia noveboracensis.

Note: The "BNF" symbol on Noah's schedule is Hay-Scented Fern (Dennstaedtia punctilobula), a true eastern-North-American native — not the tropical Bird's-Nest Fern that an earlier reference incorrectly identified.

Marker coverage

London–Harris Landscape — 5-Year Maintenance Plan

Scope: Hypothetical "all planted at once" scenario for the full plan as drawn (~700 specimens, 40 species, 8 beds). Replace "Year 1" below with the actual planting year when/if you shift to phased execution.

Your operational context: - On-site, handling most tasks yourself, hiring help for pruning / mulch delivery / heavy division - HOA stance: unknown — document includes both a "tidy posture" and an "ecological posture" for each decision point so you can pick after you read the covenants - Goal: Dense native eco-corridor that reads as intentional to the neighborhood, not abandoned

The governing tension

Native plant gardening and traditional neighborhood aesthetics pull against each other at specific, predictable moments in the year. The list below names every point where you'll have to make a choice, and gives you the rationale for either side rather than pretending there's one right answer.

Decision point Tidy posture Ecological posture
Winter seedheads (Nov–Feb) Cut back in Nov; clean beds for winter Leave all stems standing until late March; overwintering insects use hollow stems
Fall leaf drop Rake, remove, mulch beds Leaves stay in place; they're habitat and free mulch
Spring cutback timing Late Feb / early March Wait until 10 consecutive days above 50°F (native bees emerge)
Self-seeders (Chasmanthium, Sisyrinchium, Erigeron) Cut flowers before seed drop Let them spread and fill gaps
Spreading natives (Mountain Mint, Wild Strawberry) Hard-edge with spade cuts 2×/year Let them colonize their bed
Spent bloom Deadhead for rebloom + neatness Leave for seed/structure

A practical middle ground (my recommendation until you know the HOA): maintain tidy edges always (clean bed lines, mulch, pruned shrubs), and take a more ecological posture in the bed interiors. From the street it reads as "cared-for native garden"; up close it's functional habitat.

The plants that will cause trouble if ignored

Read this list once, then use it to set your own alarm reminders. These aren't maintenance theoretical — they're the specific species in your plan that will actively degrade without intervention.

Aggressive spreaders (will escape bed lines)

  • Pycnanthemum muticum (Mountain Mint) — 12 specimens, spreads by rhizomes. By Year 3 you'll need to divide. By Year 5 you may need to remove a ring and replant the center.
  • Fragaria virginiana (Wild Strawberry) — 18 specimens, spreads by runners. Expect 3–5× coverage by Year 3. Plan to edit 1×/year.
  • Chasmanthium latifolium (Northern Sea Oats) — 20 specimens, self-seeds prolifically. Cut flower spikes before seeds mature (late Sept) or you'll have seedlings in every bed within two years.
  • Solidago rugosa 'Fireworks' — 12 specimens, rhizomatous. Moderate spread but shows up where you didn't plant it.

Division required (declines without it)

  • Pycnanthemum muticum — divide Year 3, again Year 5 or 6
  • Iris versicolor / virginica — 58 specimens, divide Year 4 when centers die out
  • Sisyrinchium angustifolium — 111 specimens, tolerates neglect but blooms better if divided Year 4
  • Coreopsis 'Zagreb' — 32 specimens, short-lived if not divided every 3 years

Do not transplant (decisions are permanent)

  • Asclepias tuberosa (Butterfly Weed) — 74 specimens, deep taproot. If it's in the wrong spot, you live with it or kill it and start over.
  • Baptisia australis var. minor (Wild Blue Indigo) — 13 specimens, deep taproot, long-lived (decades). Site once, correctly.
  • Cornus florida (existing dogwoods) — 2 mature specimens, protect during any bed construction.

Non-natives flagged on plan (audit by Year 3)

  • Lagerstroemia 'Colorama Scarlet' (Crape Myrtle, 1 specimen) — Asian, fine to keep; not replacing monarch host capacity
  • Vernonia lettermannii 'Iron Butterfly' (11 specimens) — AR/OK native, not VA. Still valuable for pollinators. If purist-native becomes the goal later, swap for Vernonia noveboracensis (taller, VA-native).
  • Bird's Nest Fern — should have been substituted with Christmas Fern (Polystichum acrostichoides) at installation. Confirm this happened.

Year 1 — Establishment

The single most important year. Native plants are "low-maintenance" after they establish root systems. Year 1 is when you determine whether the whole project succeeds or fails, and it happens almost entirely through watering.

Spring (Mar–May, assumed planting window)

  • Install mulch: 2–3" of shredded hardwood on all beds except around Asclepias, Baptisia, Yucca, Muhly, Sporobolus (dry-preferring plants don't want wet mulch against their crowns — pull mulch back 3" from these crowns)
  • First deep soaking immediately after planting: soaker hose or drip for 2 hours minimum
  • Protect existing Cornus florida during any trenching or disturbance — no equipment within the drip line
  • Confirm plant substitutions — verify Bird's Nest Fern was replaced with Christmas Fern, confirm all plants match the legend (not the corrected botanical list)
  • Photograph every bed from consistent angles (you'll want this for Year 2 comparison)

Summer (Jun–Aug) — This is the hard part

  • Watering: 1" per week, including rainfall. Every plant, every week, for the entire first growing season. A rain gauge is $8 and mandatory.
  • During a VA heat wave (90°+ for 5+ days), that doubles. Check soil moisture 4" down with a screwdriver — if it comes out dry, water.
  • Deep-water methodology: soaker hose or drip, NOT overhead spray. Overhead wets foliage and invites fungal disease on Phlox, Monarda (if you had any), Asters.
  • Do not fertilize. Natives don't need it and fertilizer promotes weak floppy growth. This is a common mistake.
  • Weed aggressively around establishing natives — they can't outcompete crabgrass or stiltgrass in Year 1. Hand-pull, don't hoe (hoeing disturbs establishing roots).
  • Deadhead Coreopsis 'Zagreb' and Rudbeckia 'American Goldrush' only if you need rebloom. Otherwise leave them.
  • Expect losses: 10–15% mortality in Year 1 is normal. Flag dead spots for fall replacement.

Fall (Sep–Nov) — First decision point

  • September: Cut Chasmanthium flower spikes BEFORE seeds drop (late Sept in zone 7a). This is a permanent calendar item.
  • October: Final deep watering before winter, especially for shrubs and Cornus.
  • November — decision time:
  • TIDY POSTURE: Cut herbaceous perennials to 4" above ground. Rake most leaf litter (leave ~1" thin layer). Edge beds sharply. Top up mulch to 2".
  • ECO POSTURE: Leave everything standing. Leaves stay. Top up mulch on pathways only.
  • MIDDLE GROUND (recommended): Cut the front-facing 4' of each bed tidy (visible from street/neighbors); leave the interior 4'+ standing. Edge beds sharply regardless. This buys you HOA peace without losing overwintering habitat.
  • Replace Year 1 casualties in October/early November (cooler soil = better establishment than spring for woody plants).

Winter (Dec–Feb)

  • Nothing active. Walk the beds monthly to spot deer browse or wind damage.
  • Order Year 2 supplies by February: mulch delivery, replacement plants if needed, soaker hose expansions.

Year 2 — Transition

Still establishing, but plants are starting to earn their keep. The job this year is weeding and water-reduction. You're training the plants to rely on their own root systems.

Spring

  • Cutback timing is the big call. If ecological: wait until consistent nights above 50°F (usually early–mid April in zone 7a). If tidy: late February / early March. Either way, cut last year's growth to 4" — this applies to all herbaceous perennials and ornamental grasses.
  • Do NOT cut: Baptisia (it's a sub-shrub; just remove dead stems), Kalmia, Ilex, Yucca, Juniperus, Myrica, Cephalanthus (cephalanthus tolerates hard cut but doesn't need it), Cornus, Diervilla, Itea.
  • Light prune on shrubs: Remove dead wood, crossing branches. Itea and Diervilla can take a shaping cut now. Do not prune Kalmia in spring — prune right after bloom (June).
  • Top up mulch to 2" on perennial beds. Pull back from crowns as before.
  • Divide Coreopsis 'Zagreb' if clumps have hollow centers — dig, split with a spade, replant. Early Year 2 is OK if clumps look poor; most plants can wait until Year 3.
  • Water deeply after cutback — one 2-hour soak to wake the roots up.

Summer

  • Water reduction: Cut back to 1" per 10 days (instead of weekly). Skip weeks with rain. The goal is to force deeper root growth.
  • Weed 2× per month for the first half of summer, then 1× per month in late summer as beds fill in.
  • Spider mites and lace bugs sometimes hit Kalmia in dry summers — check leaf undersides in July. If infested, blast with water from a hose; don't reach for pesticides.
  • Deadhead Rudbeckia once in mid-July for a second flush. Leave Coreopsis alone after this year — let it seed in.

Fall — Same decision points as Year 1

  • Sea Oats cutback before seed drop (non-negotiable; permanent calendar item)
  • Winter posture decision — you should know the HOA expectation by now. Commit to one posture and hold it.
  • Divide Sisyrinchium if clumps look tired (optional; most won't need it until Year 4).
  • Plan Year 3 division work: photograph Mountain Mint spread. If it's doubled in footprint, Year 3 is division time.
  • Pycnanthemum (Mountain Mint) edge check: If you see runners outside the bed, cut with a spade 6" deep to sever rhizomes.

Winter

  • Walk beds monthly.
  • Prune Crape Myrtle late winter (Feb) — thin out crowded branches, remove suckers. No "crape murder" topping cuts.
  • Prune Cornus florida (dogwoods) late winter if needed — dead wood and crossing branches only. You noted a separate tree-pruning job for Feb 2026; coordinate with that.

Year 3 — Establishment complete, division begins

This is the transition year where the garden starts to feel mature and the maintenance pattern shifts from "keep alive" to "keep beautiful."

Spring

  • Mountain Mint division (required). Dig up each clump, split into 3–4 pieces with a sharp spade, keep the healthiest outer edges, replant at same depth, compost or give away the center (which is usually declining). Water deeply for 3 weeks after.
  • Coreopsis 'Zagreb' division (all 32, if not done in Year 2).
  • Cutback + mulch as Year 2.
  • First hard prune on Diervilla and Itea if shape needs restoration. Both tolerate cutting to 12–18" from the ground.
  • Prune Kalmia after bloom (June). Remove spent flower clusters by snapping them off with fingers (not scissors — you'll damage next year's buds).

Summer

  • Water only during drought (more than 10 days without significant rain, or high-heat stretches).
  • Wild Strawberry edit: Pull runners that have escaped the bed. Give them away or compost; don't transplant into a bed where they'll take over.
  • Bird's Nest Fern check — if original tropical species was installed, it's dead by now; replace with Christmas Fern.
  • Assess shrub screening: Myrica, Ilex, Juniper should be forming a real hedge by now. Light shape-pruning on any specimen that's outpacing neighbors.
  • Crape Myrtle — light summer prune to remove seed pods and shape. Reblooms on new wood.

Fall

  • Sea Oats cutback (still permanent).
  • Cornus florida health check: leaf miners, anthracnose signs (brown spots with purple halos). If present, improve air circulation around the tree and avoid overhead watering. Serious anthracnose = call an arborist.
  • Audit the non-native Vernonia 'Iron Butterfly': it's performed for 3 years. If purist-native matters to you, swap now for Vernonia noveboracensis. If pollinator performance is your only metric, keep it.
  • Replant gaps with plants from divisions, not nursery purchases (saves money, uses genetics already proven on your site).

Winter

  • Tree pruning year: Dogwoods, Crape Myrtle, any Taylor Juniper that's competing with structures.
  • Soil test (free or low-cost from Virginia Cooperative Extension). You've had 3 years without fertilizer; check pH especially for Kalmia (wants acidic).

Year 4 — Mature garden maintenance

By now the rhythm is established. The calendar becomes predictable. Most of the effort is editing, not installing or rescuing.

Spring

  • Iris versicolor division. All 58 specimens in the wet zones. Dig in March before new growth, cut rhizomes apart with a knife, replant with rhizome top flush with soil, water in. Share or compost the excess.
  • Sisyrinchium division — optional but worthwhile. The 111-plant mass will bloom more vigorously after splitting.
  • Mountain Mint edge control — second hard cut around the bed perimeter.
  • Hard prune check on Itea, Diervilla, Cephalanthus — these three benefit from occasional hard cutbacks to 12" every 3–4 years to renew form. Don't do them all in the same year; stagger.

Summer

  • Drought tolerance is real now. Water only in extended drought (2+ weeks).
  • Asclepias tuberosa (Butterfly Weed) observation: Monarch caterpillars should be visible on foliage July–August. Damage to leaves is the point; resist any urge to "fix" it.
  • Check for Joe-Pye / Eupatorium volunteers or other desirable VA natives self-seeding from neighboring areas. Either leave them or pot them up for friends.
  • Photograph the garden in peak bloom (August, for Pycnanthemum + asters + muhly) for the HOA, for your own records, and for future reference.

Fall

  • Pink Muhly peak display — this is the show-stopper week. Schedule a photo day.
  • Full bed audit: walk through with a notebook. Mark what's thriving, what's struggling, what you'd move if you could (you can't for some plants — see "Do not transplant" list).
  • Winter prep — by now this should be routine; follow whichever posture you committed to.

Winter

  • Structural pruning year — dogwoods, magnolias (if any get added), junipers. Every 2–3 years is the right cadence.

Year 5 — Editing, refreshing, planning for the next 5

The garden is established. It should look intentional, dense, and lived-in. This year's work is about preventing it from becoming crowded and planning the next phase.

Spring

  • Mountain Mint second division — by now you have 4× the original footprint. Keep what fits the space, give the rest away (Master Gardeners or a local native plant sale).
  • Baptisia inspection: these are now 5 years old, should be massive clumps 3–4' tall. They rarely need maintenance but check for dead stems at the center; remove.
  • Coreopsis 'Zagreb' re-division or replacement: some will be declining by Year 5. Either divide again or replace with fresh stock.
  • Kalmia 'Year 5 check': mountain laurel grown in zone 7a Piedmont clay often struggles. If they're yellowing or failing, the soil isn't acidic enough (pH should be 4.5–5.5). Amending now is possible; replacement is also reasonable.

Summer

  • Ilex glabra evaluation: Inkberry can get leggy at the base by Year 5. Hard-prune lower branches or renewal-cut the whole shrub to 18" in late winter of Year 6 if needed.
  • Plan any additions/swaps for Year 6 Fall planting.
  • Photograph everything at peak. This is your before/after for the 5-year baseline.

Fall

  • Major division + edit cycle: Iris, Sisyrinchium, Mountain Mint, Solidago — anything rhizomatous gets looked at.
  • Decide about Vernonia 'Iron Butterfly' one more time — 5 years is enough data to know if it's pulling its weight or should be swapped.
  • Replacements for any failed plants — fall is the right time for woody replacements.

Winter

  • Full pruning cycle on dogwoods, crape myrtle, junipers, wax myrtle (if leggy).
  • Write a Year 6–10 plan. By this point you know what works, what doesn't, and what the neighborhood reaction has been. The second 5 years should be refinement, not rescue.

What you'll hire out vs. do yourself

Based on "on-site, hiring help for bigger tasks":

DIY (should be yours)

  • All watering
  • All weeding
  • Deadheading, light pruning, Sea Oats seed-head cutback
  • Walking the beds, photography, pest observation
  • Division of smaller perennials (Iris, Sisyrinchium, Coreopsis)

Hire out

  • Mulch delivery and installation every 1–2 years (10–15 cubic yards; heavy labor)
  • Tree pruning for Cornus florida and Taylor Juniper — hire a certified arborist every 2–3 years (this is your existing Feb 2026 task pattern)
  • Crape myrtle pruning — technically DIYable but easy to get wrong ("crape murder")
  • Hard renewal cuts on shrubs (Kalmia, Itea, Diervilla) when they need it — not every year, but when needed
  • Mountain Mint / Iris division in Year 4–5 — physical work, back-breaking; worth $200–400 for a day of help
  • Soil amendment if Year 3 soil test reveals problems

One-time contractor relationships to build Year 1

  • A local arborist familiar with native trees (dogwoods especially — anthracnose protocols matter)
  • A mulch supplier who'll drop aged hardwood (not dyed, not fresh wood chips)
  • Maybe a garden helper — not a landscaping crew, but one person who works seasonally and learns your plants. Worth gold in Year 3+ when division season starts.

Calendar quick reference

Every year, permanent tasks: - Late September: Cut Chasmanthium (Sea Oats) before seed drop - Late October: Final deep watering - Late February / early March: Spring cutback (timing by posture — tidy = earlier, ecological = later) - June after bloom: Kalmia deadheading (by hand, snap don't cut) - Anytime growing season: Mountain Mint spade-cut edging if runners escape the bed

HOA-critical appearances (keep these sharp regardless of posture): - Bed edges — clean, defined, re-cut 2× per year - Mulch — topped up annually, not piled against stems - Front-facing beds — visible from street kept more conventional; interior can be wilder - Dead plants — removed within a few weeks, not left standing

Once you know the HOA, reduce the split-posture guidance to one answer.

Notes

This document assumes a 2026 Feb–Mar planting based on your earlier phased-execution timeline. If actual planting happens later, shift everything forward accordingly. Year numbering is relative to planting year, not calendar year.

The biggest risk to the project is Year 1 underwatering. Everything else is recoverable. A dead butterfly weed is permanently dead (deep taproot won't regenerate from a stump). Write the Year 1 watering schedule on a wall calendar, not a phone.

If the HOA posture turns out to be "minimal" / naturalistic-friendly, this plan can be simplified considerably. If it's "full cleanup expected," the middle-ground approach is doable but requires more labor — roughly 50% more hours in October–November than the ecological posture.

Final thought: The goal stated was "dense eco-corridor that maintains neighborhood aesthetic." Those two goals are compatible, but compatibility requires active management of the tension listed in the decision-points table. A hands-off native garden becomes, over 5 years, a wild native garden — beautiful ecologically, but not always beautiful by suburban standards. The difference between the two outcomes is roughly 40–60 hours of intentional editing per year, most of it concentrated in March and October.
