Helianthus sp. - I bought some seeds for a perennial sunflower many years ago from Tasmania, before I started the nursery and kept records. So I have unfortunately lost the original seed packet. But this sunflower is quite different to the other varieties I grow. It grows very talk slender stems, with no branches and flowers prolificalloy in the summer time, the flowers are yellow. It is hardy, and will spread to form a clump. If anyone sees the picture and they have an idea what it is please feel free to send me an email,
