Grab - it isn't just Cambs. London is covered in the things, all burgeoning with all forms of insect life except bloody butterflies!!If you want to use it as a cut flower, cut it in the cool of the evening, and stick it in water immediately. It keeps its leaves then, but if isn't well watered, it will go brown. Great for those quick displays at church where there is a huge vase and no other flowers....!
Nasturtiums - plant 'em once, you'll never need plant 'em again!! I still have some going strong from the seeds shed 2 years ago! One is climbing up the back fence and the other is making a bid for the buddlea.
