Portulacea grandiflora is the one I have to plant each year. I even have a big glazed pot reserved just for portulacea .The pot is on a sunny side and portulacea I plant there have to be of different colours. When new flowers bloom it looks like a bouquet is arising from the glazed pot, each day a new bouquet, as different coloured flowers bloom in various combinations. There is only one rule, portulacea are in full bloom only on sunny days, at about ten o’clock in the morning. Just a perfect time to have a Sunday morning coffee!
