Pinus strobus Sea Urchin

Pinus strobus ‘Sea Urchin’ is a distinctive dwarf eastern white pine valued for its dense, rounded form and spiky, textural foliage. This slow-growing pine forms a compact, mounded shape with short, stiff blue-green needles radiating outward, giving it a bristly, sea-urchin-like appearance year-round. Typically reaching 3–5 feet tall and wide, ‘Sea Urchin’ thrives in full sun and prefers well-drained soil, adapting well once established. Its unusual texture, manageable size, and strong character make it an excellent choice for rock gardens, collector plantings, and landscapes seeking a white pine with bold visual interest.
