It is also known as wildflower.
They grow from bulbs. The bulbs look like shrivelled small acorns.
Place the corms on a wet paper towel for a few hours and frequently add more water on top so that they swell up. You can then add a layer of soil to a tray and add the bulbs on top and cover with a thin layer of more soil, keep the soil moist and keep the tray in a dark cool place for two weeks. When the roots are established you can place them in a container pot.
Each plant can produce many flowers.
Make sure the soil is regularly fertilised.
