My Hoya linearis, that is hanging in the garden all summer, usually blooms when I take it inside in the autumn when the night temperature reaches about 5°C.
This year it has decided that now is the time. It actually suits me well because the flowers are too heavily perfumed for my bedroom.
Now I'm keen to see if there are any Danish night insects that take interest in the flowers, so that I may have some seeds. It would be great to start a new pot from seeds, wouldn't it.
