Sweet peas hybridise readily. A small selection should produce lots of interesting colours within a year or two. They were used in early genetics studies because of their easily recognisable features of colour, petal shape and height.

Quietly writing at my desk recently, I nearly jumped out of my skin at what sounded like a gunshot right under my nose. It was rapidly followed by another and then a third. To my total disbelief I saw some sweet pea seed pods, saved from last December and lying in a little dish on the blotter, were busily exploding and shooting out tiny bullet-like seeds in every direction.
