Newly bought plants now flowering

I have been trying to grow some choice alpines, in a dedicated rock garden in my garden here in Sheffield, for some years. Many have not survived the winters, so recently I set up a new greenhouse to use as an alpine house.

Hi Keith, welcome to the forum. What exactly was your question. I'm assuming you have some plants in pots with flowers on at the moment. Which plants are they? Martin

In November this year I went to Harlow Carr to see the alpine houses there and to see how they do things. I bought several plants, none of which were then in flower. Two of these plants, Lewisia cotyledon and Polygala calcarea "Lillett", are now flowering in my alpine house, considerably earlier than it seems they should. Should I remove these flowers?

Hope Iv'e got the formatting right here, and hope this is not a silly question.

Just seen the punctuation error - should be "I've"!

Newly bought plants flowering

I have had this problem too, with my own plants flowering unseasonally as well. Strange weather always brings about anomallies, too. I take the view that in winter the flowers will not survive long and should be removed as soon as they have died, to prevent rotting problems. It may well be that the plant will not flower next year but it will catch up eventually.

Keith, it is not unusual for Lewisia cotyledon to throw up occasional flowers at almost any time of year, particularly on young plants. It shouldn't be too detrimental to next Spring's flowering but I would agree with Elzabeth's comment to remove the flowers as they start to fade. The dead flowers will most likely be attacked by Botrytis or some other fungus at this time of year which can then spread to the whole plant. I have no experience of Polygala Lillet flowering out of season (I usually kill it before it has a chance)but would suggest similar treatment.

Thanks Elizabeth and Martin. Keith
