Title: Sedum sempervivoides
Post by: Philippe on February 04, 2012, 09:31:15 AM

Hello

A superb monocarpic plant...Problem is that I almost never get any seed from the plants that have flowered in the garden. Stock renewal in this way is a tricky thing for me.
I had luck in summer 2010, I could harvest, let's say... "some" seeds, of which 3 or 4 have germinated in 2011... Hope the young plants will have make it through this winter upthere in the alpine garden

I have already tried to cut away leaves on a non flowering rosette, but with no result.
Can this species be multiplicated vegetatively?
Or is it possible to cut through the rosette to avoid flowering and encourage side rosettes production, like Saxifraga longifolia?
I guess you, growers of it, rely mainly on reliable seed production each year to get new plants, and probably never had the idea of doing such things, isn't it?  ::)

I am growing Sedum sempervioides for nearly 50 years. Sometimes I got seed sometimes not. Have patience!!
By the way, it is not a easy plant!

I may have patience, the sedum not, though  :D Once its "things" are done ( or not in my case most of the time), he just leaves, without any good bye!
Yet it seems to appreciate our weather conditions. The few plants I have are doing well, even if they take their time to reach flowering size ( at least 3 years from seeds on).

I managed to grow 12 plants from seed last year. I lost 2 in winter, but have 10 left. 2 of them have formed an extra small rosette.
Can I take of these small rosettes to be sure I will have 2 plants that probabely will bloom a year later? And if possible, how do I do that?

I won't give you the answer Jonna, but I would anyway find it risky to get the side rosette away from the main one. Why not just let them both undisturbed? If the main rosette flourishes this year, the smaller one will probably do so, but only next year, wouldn't it?

Sorry for my late reply Philippe.
I will leave the side rosette on the plant and see what happens.
