Regional Picks: Spring Color—Northeast

Fine Gardening - Issue 192
Showy Lantern enkianthus

If your first few trips to the nursery can be overwhelming and chaotic, check out our plant recommendations for spring color in your region. There’s no doubt that these spring flowers will cure the winter blues.


1. ‘Roadrunner’ trillium

‘Roadrunner’ Trillium

Trillium pusillum ‘Roadrunner’

Zones: 5–9

Size: 8 to 12 inches tall and 24 inches wide

Conditions: Partial to full shade; acidic, moist, well-drained soil

Native range: Southeastern United States

This early bloomer is a pleasant surprise in the spring garden when its lovely white, up-facing petals unfurl atop deep greenish-purple sepals and a whorl of similarly colored leaflike bracts. Each pristine petal, backed in rose, has a wavy edge and fades to soft pink as it matures (pictured). In contrast to most other trilliums, which are usually slow to spread, this gregarious little charmer forms satisfying clumps over time, expanding by underground runners. Perhaps the best way to describe ‘Roadrunner’ is “Utterly charming.”


2. Mount Odae iris

Mount Odae Iris

Iris odaesanensis

Zones: 5–7

Size: 5 to 8 inches tall and 2 to 4 feet wide

Conditions: Partial to full shade; rich, mildly acidic to neutral, moist soil

Native range: China, eastern Korea

Blooming in midspring, the lovely, creamy white, 1-to-2-inch-wide flowers of this small iris are borne on 3-to-5-inch stems. The leaves, grassy and green, arch elegantly and continue to lengthen after the flowers fade. It is an easily cultivated perennial, though not commonly grown, and increases in girth through underground rhizomes. This little beauty has become quite rare in its native South Korea and is now classified as endangered—all the more reason to include it in our gardens.


3. Pheasant’s eye

Pheasant's Eye

Adonis vernalis

Zones: 3–7

Size: 6 to 8 inches tall and 12 inches wide

Conditions: Full sun; well-drained soil

Native range: Europe

I don’t know what I love more: the feathery, ferny foliage or the sunny flowers of this diminutive spring bloomer. It shows up (mid-April to early May in New England) as if to bring a bit of the sun down to warm the ground. Twelve to twenty gleaming yellow petals with a distinct sheen surround a central hub of stamens and pistils. The contrast of these bright flowers against the fine green foliage is lovely; the flowers, though only 2 to 3 inches wide, seem so bold and brilliant on this spring ephemeral. Like many spring gems, this beauty goes dormant in summer.


4. ‘Showy Lantern’ enkianthus

‘Showy Lantern’ Enkianthus

Enkianthus campanulatus ‘Showy Lantern’

Zones: 4–7

Size: 8 to 10 feet tall and 6 feet wide

Conditions: Full sun to partial shade; rich, acidic soil

Native range: Japan

‘Showy Lantern’ enkianthus is the most dramatic cultivar of this fine specimen shrub. Related to blueberries and rhododendrons, it grows happily in the same conditions: moderately well-drained, acidic soil in full sun or partial shade. Given these conditions, ‘Showy Lantern’ will celebrate spring decked out in small, dangling, jewel-like ruby bells, each decoratively striated with deeper red veins and held on slender, light green stems among deep green foliage. Selected by famed plantsman Ed Mezzit of Weston Nurseries, this shrub stands out from its creamy-flowered cousins. It is awash with fiery red and orange leaves in autumn, making it one of the best shrubs for fall color.

    Matching a plant to a place with the right amount of sun can be tricky! The amount of sun varies by time of day, and season, so most people just guesstimate.
    But you don't need to guess any more!
    A new app in the Google Play Store tells you exactly how much sun or shade any place will get.
