Thanks, Steve, I will do that and I hope for some results. Diana > You should give them plenty of sun & increase watering to good solid drenching as the heat increases.. Some have success with the water tray method sitting them I'n a little water through summer... The endemic native ones here I'n Queensland live on open dark clay soil & live I'n low pockets that become sodden or even water covered for a month to three months or more at a time.. I am always fascinated when i visit the area to see plants I'n water 8" deep with healthy foliage & producing healthy buds & flowers for months.. Greater numbers of bulbs are above the water line but remain with their roots I'n water drenched soil..
