It's interesting that several people have mentioned Crocosmia as not growing in their gardens. I planted a group of them about 4 years ago and all I've ever had is leaf growth and no flowers.
However, the leaf growth this year has been stronger and lo and behold, a week ago they started to flower. I don't know if it was the second move at the end of this winter or if they take some years to produce flowers? Obviously I'm glad I didn't chuck them because they are very pretty.
They're in the front garden, which is East-facing and in very rich soil on a clay base.
I seem to be able to grow almost anything here in Sheffield but like some have mentioned I haven't had any success with Echinacea, though I've only tried once.
Fishy 65, you mention not having any luck with Sunflowers. Clearly I don't know the circumstances but I've found that sunflowers will grow almost anywhere, I've seen them growing out of concrete and tarmac.
Five feet is not bad for some varieties of sunflower. I grow a variety of sunflowers every year, including giants and get a lot of self-seeded plants. At the moment I have one that is about 7-8 feet that self-seeded in the centre of the garden.
This space is pure clay with builders rubble in it and it's been covered with a double layer of weed control fabric and decorative stone! I do feed my sunflowers with either a general purpose plant food or tomato feed. I have experimented though with not feeding some and they have grown well with just regular watering.
So please don't give up because they are wonderful plants, an essential summer plant that will flower from summer into winter in the right weather conditions.
