Apparently, Sanguisorbas are the height of fashion now, so I am on trend, hurray! I’ve tried growing them from seed a couple of times over the years from packets received from the RHS members seedlist, but for whatever reason I’ve failed. This year I am trying again with two different kinds from a different source: http://www.seedaholic.com.
The first I’ve chosen is the beautifully tactile Sanguisorba tenuifolia ‘Alba’ (a variety of Japanese Burnet), which looks like dangling little lambs tails. The other is the standard, but effective Sanguisorba officinalis (Greater Burnet, an ancient herb and wild flower of Britain) with tight, wine-red drumstick heads. They are clump-forming herbaceous perennials and have remarkably robust spikes of flowers from June -August reaching between 1m and 1.5m.
The seeds were both sown today. The instructions say they are best germinated in a cold frame, typically when temperatures reach between 10-14 degrees centigrade. Seedlings may take 2 months to start appearing (assuming that they do). Mine are in a cold greenhouse and I have my fingers crossed for this attempt. Watch this space ….
