Spring: The Explosive Awakening

6 min read

Spring Garden Design

Spring is when your garden goes from dormant to dramatic in weeks. Planning for spring means thinking about SEQUENCE — the best spring gardens have something new opening every week from March through May.

The Spring Timeline

Late Winter / Early Spring (Feb-March)

  • Witch hazel — Fragrant spidery flowers on bare branches
  • Hellebore — Nodding flowers through snow
  • Crocus — First tiny bulbs through frozen ground
  • Winter jasmine — Yellow flowers on green stems

Early Spring (March-April)

  • Daffodils — Plant 100+ for real impact
  • Forsythia — Golden explosion before leaves
  • Redbud — Pink flowers on bare branches
  • Serviceberry — White clouds before anything else leafs out

Mid Spring (April-May)

  • Flowering cherry — The Instagram moment
  • Dogwood — White or pink bracts
  • Azalea & Rhododendron — The big show
  • Tulips — Rainbow beds
  • Bleeding heart — Arching hearts

Late Spring (May)

  • Lilac — The most legendary fragrance
  • Peony — Enormous, fragrant, romantic
  • Iris — Every color exists
  • Mountain laurel — Geometric perfection
  • Clematis — Climbing color

The Spring Design Formula

For every bed, include:

  1. One spring-flowering tree or large shrub (redbud, dogwood, serviceberry)
  2. A mass of spring bulbs underneath (100+ daffodils, crocus)
  3. Two spring-blooming perennials (bleeding heart, hellebore)
  4. Evergreen structure that frames the spring show (boxwood, holly)

Pro Tips

  • Plant bulbs in FALL for spring bloom
  • Layer early + mid + late bulbs for 8 weeks of continuous color
  • Don't cut bulb foliage until it yellows (6 weeks after bloom)
  • Plant bulbs among perennials — the emerging perennial foliage hides the dying bulb leaves

Summer: Peak Performance

6 min read

Summer Garden Design

Summer is when your garden should be at its peak — the longest days, the most growth, the fullest display. The key is CONTINUOUS BLOOM through succession planting and strategic deadheading.

The Summer Powerhouses

June

  • Roses (Knockout, Drift, David Austin) — Non-stop color
  • Daylilies — 200+ blooms per plant per season
  • Salvia 'May Night' — Electric blue spikes
  • Catmint — Lavender clouds, first flush
  • Baptisia — Indigo blue pea flowers

July

  • Coneflower — The backbone of summer color
  • Black-eyed Susan — Golden masses
  • Bee Balm — Hummingbird magnets
  • Hydrangea — Mopheads, lacecaps, paniculatas
  • Daylilies — Reblooming varieties still going

August

  • Joe Pye Weed — 6-foot butterfly magnets
  • Limelight Hydrangea — Lime green cones turning pink
  • Ornamental grasses — Plumes starting to emerge
  • Phlox — Fragrant, full-sized flowers
  • Zinnia — Non-stop annual color

The Heat-Proof Lineup

These plants don't flinch when it's 95°F:

  • Lantana, Blanket Flower, Red Yucca, Agave
  • Crepe Myrtle, Salvia, Butterfly Bush
  • Ornamental Grasses (all of them)
  • Sedum, Yarrow, Russian Sage

Summer Maintenance That Matters

  1. Deadhead roses, daylilies, coneflower for repeat bloom
  2. Cut back catmint and salvia by half after first flush → full rebloom in 3 weeks
  3. Water deeply once/week, not daily sprinkles
  4. Mulch if you haven't already — it's essential in summer heat

Fall: The Underrated Season

6 min read

Fall Garden Design

Fall is the most underplanned season in most gardens — and potentially the most spectacular. Between foliage color, ornamental grasses at peak, and fall-blooming perennials, autumn can rival spring for garden impact.

The Fall Stars

Foliage Color

  • Sugar Maple — Orange/scarlet, the gold standard
  • Red Maple / Autumn Blaze — Reliable scarlet
  • Japanese Maple — Crimson, orange, gold
  • Burning Bush — Electric red
  • Oakleaf Hydrangea — Burgundy/mahogany
  • Nandina — Red/scarlet year-round peak in fall

Grasses at Peak

This is ornamental grasses' MOMENT:

  • Pink Muhly — Cotton candy pink clouds
  • Maiden Grass — Silver plumes catching golden light
  • Karl Foerster — Wheat-gold columns
  • Little Bluestem — Copper-red with silver seed heads
  • Switchgrass — Burgundy columns

Fall-Blooming Perennials

  • Aster — Purple, blue, pink masses
  • Goldenrod — Golden plumes (NOT the allergy culprit)
  • Sedum 'Autumn Joy' — Pink turning rust
  • Japanese Anemone — Elegant pink/white
  • Toad Lily — Orchid-like shade flowers

Berries & Fruits

  • Beautyberry — Electric purple clusters
  • Winterberry Holly — Brilliant red
  • Viburnum — Blue, red, or black
  • Crabapple — Persistent red/orange fruits

The Fall Design Secret

Mass ornamental grasses. Nothing else creates fall magic like a drift of 5+ muhly grass or little bluestem glowing in autumn light. Interplant with asters and sedum for a fall border that rivals any spring display.

Winter: Structure, Bark, Berries, and Evergreens

7 min read

Winter Garden Design

Winter reveals the skeleton of your garden — and either it's beautiful or it's bare. Planning for winter interest separates good gardens from great ones.

The Winter Elements

Evergreen Structure (The Backbone)

Without evergreens, your winter garden is just sticks:

  • Boxwood — Green geometry
  • Holly — Glossy + red berries
  • Arborvitae — Green walls
  • Juniper — Blue-green carpets and columns
  • White Pine — Soft, billowing presence
  • Blue Spruce — Silver-blue statement

Rule of thumb: At least 30% of your plants should be evergreen for winter impact.

Bark (The Hidden Beauty)

When leaves fall, bark becomes the star:

  • River Birch — Peeling salmon, cinnamon, cream
  • Japanese Stewartia — Patchwork of olive, gray, cinnamon
  • Paperbark Maple — Cinnamon peeling bark
  • Crape Myrtle — Smooth, mottled bark
  • Scotch Pine — Orange-cinnamon upper trunk
  • Sycamore — Cream and green camouflage

Berries That Persist

  • Winterberry Holly — Brilliant red on bare stems (THE winter plant)
  • Beautyberry — Purple into early winter
  • Nandina — Red berry clusters
  • Crabapple — Red/orange persistent fruits
  • Viburnum — Various colors

Winter Bloomers (Yes, They Exist)

  • Witch Hazel — Fragrant yellow/red spidery flowers, Jan-March
  • Hellebore — Nodding roses, Feb-March
  • Winter Jasmine — Yellow flowers on green stems
  • Camellia sasanqua — Fall through winter in the South

Ornamental Grass Skeletons

Don't cut grasses down in fall! Leave them standing:

  • Karl Foerster — Golden wheat columns
  • Switchgrass — Russet columns with seed heads
  • Maiden Grass — Flowing buff plumes
  • Little Bluestem — Copper tufts with silver seeds

They look stunning with frost, snow, and winter light.

Winter Design Formula

For every view from inside your house:

  1. At least one evergreen anchoring the view
  2. One tree with interesting bark
  3. One plant with winter berries or flowers
  4. Standing ornamental grasses for movement

The Takeaway

Plan your garden from winter BACKWARDS. Get winter right, and the other three seasons are a bonus. Get winter wrong, and you stare at bare soil for 4 months.
