Thank you Treehugger - I have very hard water so I use rainwater or de-ionised water.
I have 6 pots in a tray and keep them on a sunny patio - am now interested to see how these round flower buds will look when the flowers come out. The ones I have are called purpurea, flava Purple Tube, alata rubrioperculata, farhamii, ,moorei, harperi. I will get some fleece to put over them on cold nights in the winter as you recommend it.
