Some of the cultivated flowers are really spectacular. I planted 3 Tree Lily bulbs in a large pot and the first year we had 45 flowers and in the second year they produced 115 large flowers! Having said that I find some of the small flowers are excellent.
We tried the Tom Tat (tomato grafted to potato) in a hessian bag and had a crop of 3 kilo of potatoes and over 100 small juicy tomatoes. My old Rose is still the best scented flower.
