FAQ

Why do Portulaca flowers close in the evening?
It is a heliophilic plant: flowers only open in direct sunlight and close at sunset and on cloudy days, to protect stamens and pistils.
Does Portulaca self-seed?
Yes, it self-sows: in autumn it produces tiny seeds that fall to the ground and germinate spontaneously the following spring, creating new flowering carpets.
