Leucoseptrum japonicum 'Variegatum'

Japanese Shrub Mint

Plant Type:

SHADE PERENNIALS

Leucoseptrum japonicum ‘Variegatum’ (probably the same as 'Mountain Madness') – Leaves, much narrower than the species, are nevertheless broader than the two angel forms. The showy gold splashes are bold, irregular, and mature to creamy white starkly contrasted with the remaining dark green of each leaf. Byron W. from Long Island tells us that they are very good late season bee plants. In autumn these may arrive pruned.

Genus Overview: Leucoseptrum

Common Name: Japanese Shrub Mint

Leucoseptrum stellipilum. This is a curious late-blooming clump forming mint relative. Note that I said "clump"; it harbors none, zilch, zero of the aggressive tendency to tenaciously dominate an area. With large and showy feather flowers they make a striking statement at the end of the growing season. Though hardy in USDA zone 5 we have determined that our growing season is not quite long enough to support the flowering event, at least in most years. The Japanese Shrub Mint all by itself gives me zone envy! They make interesting contrast plants in the late season garden. And the variegated, silver and gold-leaved forms provide lovely contrasting foliage to other garden compatriots all through the growing season. In the north site in full sun planted in fertile soil. Farther south they will be perfectly content in some open to dappled shade conditions; after all, Leucoseptrum originates in Japanese woodlands. Better in gardens with a longer growing season I expect that it would do nicely on Cape Cod with their moderated extended autumns and certainly does well on Long Island and southward. In fact, Byron W. from Long Island tells us that they are very good late season bee plants there. That's always good new! Cutting grown. We offer 2 separate species with associated cultivars, Leucoseptrum stellipilum and L. japonicum.
