I got this plant last summer. It was put straight into a piece of tufa facing north east, one of the six holes I had awaiting plants. The rosette has doubled in size and produced a beautiful deep red bud/flower. There is also a new rosette just coming through from the side of the main rosette as you can see from the picture.
My questions are, Can I remove the new rosette to make a new plant. When is the best time to do this, its still only very small. If and when it?s removed will it take planted straight into a tufa hole?
Finally will it produce seed and can this be put straight into a tufa hole?
It is a super looking plant.
PS; Had a great day at the Loughborough show yesterday. Looking forward to Chesterfield
I should wait until it has grown a lot more and then, yes, remove it in the autumn (the time for most Saxifraga cuttings to root). Put it into a mixture of equal parts Grit sand and Perlite and set aside.
You could also let it set seed and raise this in a similar mixture.
It seems a pitty to remove the only side rosette. As it is growing in tufa at will be very slow.
Sprinkle the seed straight onto the tufa. No hole needed.
I too had a wonderful day at Loughborough. Nice things to buy. Lots of people to chat to and such wonderful plants on the benches.
Thank you for the advice and info. I will as you suggest leave the rosette on the plant until it gets to a decent size and then look at removing it to get another plant going. I honestly don?t know if the griesbachii rosettes die off after flowering, or build up with more rosettes. The one plant I have, the one in the picture, it?s flower stem has now turned into a really deep red, much darker than the picture, and looks even better.
I must say a very nice Saxifrage.
