Just take the pot leaf, drop it in water and it will grow in only a few seconds. Now that’s gardening that keeps you on your toes. If only real plants grew so fast, I might not have killed every flower that I decided to put into soil. Although this particular form of weed won’t have quite the same effect as the slow growing version, this kind won’t get you arrested either. Plus it’s cheap, one of these quick growing leaves will cost you £1.99 or about $2.85.
