Pachyphragma

Pachyphragma macrophyllum
A rhizomatous, clumping perennial, reaching up to 1.5 x 3 feet, that makes an excellent groundcover in the Pacific Northwest though it native in wet deciduous forests from northeast Turkey to the Caucasus. It is a very attractive, non-invasive relative of Garlic Mustard.
The scalloped, rounded leaves are deep green.
The small, white, 4-petal flowers are borne on terminal, rounded heads during early spring.
Hardy zones 5 to 9, it enjoys moist, humus-rich, well drained soil in deciduous shade where there is early spring sun before the forest canopy closes in providing summer shade.
During summer it is both deep shade and dry shade tolerant as well as very tolerant of heat. Propagation is from division during early spring or seed sown during autumn.
