Jeffersonia dubia “Putnam’s Blue”

Name change to: Plagiorhegma dubia "Putnam's Blue", but I can't bring myself to call it that.

The Asian Twinleaf is a choice perennial that any “real” garden can’t be without, and the more, the better. It blooms very early in spring, usually starting a couple of weeks before the epimediums. Its flowers fade quickly if the suddenly weather heats up. Flowers of "Putnam's Blue" open a deep blue-lavender, and fade with age. The blossoms seemingly float above the rounded, wavy-edged, almost waterlily-like leaves.

Plants bloom at about 4-6” tall, each leaf expanding to 2-3” or so across eventually forming a dense clump 8-10” tall. This selection has the same rusty-red new growth in spring, but is deeper blue-lavender in bloom than ‘Dark Centers’ with a green ovary and longer, fatter, sculpted petals. These are seed grown as Jeffersonia defies division. It originally came from Bob Putnam’s nursery via Jim Jones.
