(Pachyphragma macrophyllum) Synonyms:  Thlaspi macrophyllum Genus:  Pachyphragma Rounded, ruffled leaves form a solid, weed-free, evergreen ground cover. In the spring, elongating shoots open to rounded heads of small four-petaled white flowers. Plants remain in bloom for nearly a month, opening new flowers from expanding terminal clusters as well as from numerous side shoots. Mature plants stand 12 to 18 inches high when in flower, and spread in time to form clumps 2 to 3 feet wide. Noteworthy Characteristics:  Heat tolerant. Attractive leaves and flowers. Good ground cover and as underplanting for shrubs. Related to garlic mustard, but not invasive. Care:  Provide humus-rich, woodsy soil and full sun or light shade while in active spring growth. Tolerates dense, dry shade in summer. Propagation:  Sow seed in containers in a cold frame in fall, or divide or take basal stem cuttings in late spring. Problems:  Slugs.
