Known as the gem of the woodland garden, Glaucidium palmatum or Japanese Wood Poppy, is a highly sought-after rhizomatous perennial. Its broad, palmately-lobed leaves are a unique light green that make it an unforgettable addition to any garden. From late spring to early summer, it shows off large four-petaled flowers, colored in shades of mauve and lilac, that grow 2 inches across and sport a bouquet of prominent stamens. Resembling miniature peonies or poppies, its foliage and blooms make it a must-have plant for green thumbs. Keep in mind that this perennial thrives in cool, moist climates, and needs protection from desiccating winter winds. The plant is long-lived, adorning your garden for many years when grown properly, reaching up to 20 inches in height and width. It prefers humus-rich, well-drained soils and fares well in part shade to full shade. This specie is perfect for garden edges, cottage gardens, city gardens, or rock gardens, ideally planted in groups of 5 to 10. Easy to grow and virtually disease-free, the only menace that it faces are slugs. Propagation can be done through seed sowing in spring or careful division of mature clumps. This plant is native to the mountainous woods of Japan and an acknowledged winner of the Royal Horticultural Society's Award of Garden Merit.
