Long Island Perennial Garden Design: Four-Season Interest for Sun and Shade

Creating a one-time investment perennial garden on Long Island (zone 7) requires strategic plant selection for continuous color and winter structure.

Sun Garden Timeline

• Early Spring: Bulbs (crocus, daffodil, tulip, hyacinth).
• Late Spring: Peonies, iris (stagger: dwarf → Siberian → German → Japanese → spuria).
• Summer: Daylilies, coneflowers, hardy hibiscus, Russian sage, knockout roses, crape myrtle, vitex, rose of Sharon.
• Fall: Asters, mums, sedum, surprise lilies.

Shade Garden Foliage Focus

• Crested iris, wood poppy, hardy geranium, astilbe, hosta, lungwort, Jacob's ladder, ligularia, rheum, columbine, lady's mantle.
• Foliage texture/color > flowers in shade.

Winter Structure

• Evergreens: boxwood, holly, dwarf conifers.
• Deciduous with interest: redtwig dogwood, winterberry, paperbark maple, witch hazel.
• Ornamental grasses (leave standing).

Potted Perennials

Hostas, heucheras, ferns, dwarf conifers—overwinter in garage or bury pots.
