Portulacas are probably the first plants i helped grow .. in a pot sometime way back i nthe 80s. They continue to be among my favorite flowers.. They seem so ingenious .. all they need is water and a lot of sun.. give them that and they will happily bloom away. Something about these little round flowers with their bright colours and perky appearance has never failed to bring some joy into my summer mornigns. They are propogated so easily - pluck a bit of the stem and stick it into the soil after the sun has set, give it some water and voila! it is ready to bloom in the scorching sun in a few days.
