Here is a photo of my Acaena saccaticulpula Blue Haze. I was wrong about the name in my first post. Anyway, it is growing well but not keeping out weeds as well as I might like, sweet yellow clover, willow herb, and grass are coming up in that bed.

I'm getting seeds for a couple of Sanguisorbas from JL Hudson but not the low-growing one I want to use but passed up because of the price at a fair. Perhaps I'll find one again. Does anyone know a source for seed for one that gets 12" tall? I will have seed for Sanguisorba minor, the one I grow, when it ripens.

--Sanguisorba officinalis.
'GREAT BURNET'. Dark purple flowers in 1" spikes. Pinnate leaves. An elegant perennial to 5 feet. Eurasia. Sow in March, thin to 9" apart. The leaves are eaten in salads. Medicinal. Germinates in 1 - 3 weeks, and is improved by 4 weeks cold.
--Sanguisorba tenuifolia.
Pink flowers in dense cylindrical 2 - 3" nodding spikes from July to October, in clusters held above the large basal pinnate leaves. Hardy perennial to 4 feet. Wet meadows and streambanks of NE Asia. Hardy to Zone 4. Good cut flower. Germinates in 2 - 6 weeks.
