A fully double green form found in Michigan by Betty Blake and named for her which only seems right. This has quite perfect flowers which are more art than botany and whose function lies strictly in the aesthetics rather than in the somewhat banal business of procreation. Not that the latter isn't fun........................
A new Japanese selection of a favorite eastern US wildflower. This has double white flowers which are quite large and are not the domed buttons of say 'Oscar Shoaf' but more of a flattened button with a thick frill of petals. This will bloom for many weeks on an established clump. These are divisions from our plants and very choice.
One of the truly choice plants coveted by the rock gardeners who love everything wee and precious. This is tougher than its size suggests handling the open garden or doing well in troughs or containers. Goes summer dormant and increases from year to year. Half sun or dappled shade.
Very new selection out of Japan that is like a slightly less tight and paler 'Cameo'. These are surprisingly tough tuberous perennials native to the eastern US and will go summer dormant but before that happens, you will enjoy many weeks of long-lasting double flowers on an eventual impressive-for-its size clump.
