We've all bought one in ASDA or the likes - a little 10cm tall basil plant that you get in a pot and after you've used a few leaves it is meant to grow back. I don't know if my family just eats too much basil or what but they never work for us and we end up with one spindly stem with a few pitiful leaves at the top. We've tried growing them from seed too, with no greater success. We've even tried various ways of propagating them from each other, which also seems to take longer than forever... One day back in winter Thomas and I were out at Vissenberg bageri (our local prize-winning bakery), for a change we dropped into the Coop in that town instead of any of our more local ones and they were selling slightly bigger basils than we were used to. Given they were going for 20kr (the equivalent of about £2.30), we thought we'd give one a go. What a difference! It grows back quicker than we can eat it and we have now been living off it for more than 3 months without making an obvious dent in it! Size really does matter after all. Result!
