Sea Urchin Eastern White Pine

Sea Urchin Eastern White Pine (Pinus strobus 'Sea Urchin')

Sea Urchin Eastern White Pine is a compact evergreen conifer that adds soft texture and a playful, sculptural form to small landscape spaces. Its dense, rounded habit creates a neat, finished look in beds year-round, especially through winter when structure matters most. This is a great choice for rock gardens, foundation accents, and conifer collections where you want something distinctive without extra maintenance. If you want a tidy evergreen with white pine softness and a collected look, Sea Urchin is a strong fit.

Distinctive Features

This dwarf eastern white pine forms a tight, rounded mound with short, soft needles that create a plush, tufted texture. Needle color is typically green to blue-green, adding a cooler tone that pairs well with both dark evergreens and lighter foliage plants. The dense branching keeps the silhouette compact and clean, giving it strong winter presence even at a small scale. Its overall look is textured and sculptural, making it feel like a miniature specimen conifer in the landscape.

Growing Conditions

• Sun: Full sun to partial shade, with best density and form in full sun.
• Soil: Prefers well-drained, slightly acidic soil, and it adapts to a range of soils when drainage is good.
• Water: Water regularly during establishment, then provide deep watering during extended dry periods.
• USDA Zones: Zones 3 to 7.
• Mature Size: Typically grows about 2 to 3 feet tall and 3 to 4 feet wide over time.

Ideal Uses

• Focal Point: Use as a focal point in a small bed where the rounded form and tufted texture can be appreciated up close.
• Rock and Gravel Beds: Pair with stone and gravel mulch to highlight form and keep the look low-maintenance.
• Foundation Accents: Place near an entry or along the front of a bed for compact evergreen structure.
• Conifer Gardens: Add to a conifer collection for unique texture and small-scale structure.
• Front-of-Border Anchor: Use at the edge of mixed borders to keep plantings looking finished through winter.

Low Maintenance Care

• Watering: Keep evenly moist the first year, then water during drought to maintain vigor.
• Mulching: Mulch over the root zone to conserve moisture and protect roots, keeping mulch off the trunk.
• Pruning: Prune lightly in late winter or early spring to remove dead tips and refine outline if needed.
• Spacing: Allow room for spread so the mound can stay full and balanced without crowding other plants.
• Site Selection: Choose a site with good drainage and avoid low spots where water collects around the roots.
