This is such a useful little plant for summer. It's a bit late now over here in England, but if you buy just one packet of seeds at the start of summer, you will have a dazzling display in a tub on your patio or in the border. They flower all through the summer, when the sun comes out! So pretty, just like little stars!
They are annuals, so will only last for one season, but, as you can see, they are well worth it.
Mesembryanthemum, originally from southern Africa.
