Hello Cinta, I do not grow that series of ice plant, but here is what I have in our garden, grown outdoors year round.
Our location with our mild winters is quite conducive for them, and I get their blooms in Spring. The long 6 to 7 months of dry and hot months is semi-dormant time for them and they resume active growth and more plump leaves once our Fall cool temps and mild winter returns with some rains.
Oscularia caulescens
Lampranthus 'Pink Kaboom'
