Species: Impatiens walleriana.
I've grown Busy Lizzies since I began gardening & the only ones that existed were the deep pink form that could grown up to 50 or 60 cms. Nearly every house in the land used to have an ancient plant sitting in a saucer of water!
Now you can buy Busy Lizzie plugs in any supermarket when doing your shopping & for a fiver you can get a couple of dozen plants that are short & bushy & covered in flowers for 6 months or more!
They are so versatile they serve as indoor plants, bedding plants or in hanging baskets where, as some of my photos show, they look absolutely gorgeous!
