When we first started this garden we had very few flowers. A neighbour gave me the seeds of her Altea (Hibiscus syriacus). There is a similarity between the flowers and the flowsy tropical Hibiscus. The H. syriacus is a hardy deciduous plant that stands up well to our hot dry summers. Because I grew mine from seed I have a variety of colours and I find the bushes work well as a hedging plant. They can be cut with impunity in the winter and shaped high, low or fanned. I have even seen it grown into a small tree in this area. I have also read that the flowers are edible but I have not tried them yet. Certainly they would be excellent for food decoration.
I love Cosmos flowers even though they herald the end of our summer. September is often a warm, sunny month in the Charente-Maritime – still beach weather. The coloured Cosmos self-seed but I try to add variety by sowing some fresh bought seed although I do not think they are so successful. I often end up finding little seedlings struggling here and there and transplant them to sunnier spots. Cosmos love the sun and I can never find enough sunny spots for them in the garden.
