Over a year ago, I bought a young muehlenbeckia astonii from a garden centre. I potted it in a huge terracotta urn and it is growing splendidly. This year I have found several tiny muehlenbeckia astonii seedlings growing in cracks between paving stones in my garden and around the periphery of the urn that holds the mother plant. I have learned that my plant must be female and is rare. It also means there are other male plants growing in the vicinity. Given that this species is endangered, I wonder what there is for me to do to assist with conservation of this rare plant. Advice would be welcome.
