Black Eyed Susan

[Lazzerelly]

Are black eyed susan perennials and if so when can I move them. They are in full flower right now, thanks in advance

There are quite a few plants with that common name, do you mean rudbeckia?

If Rudbeckia:

I'm sorry, but I cannot answer your question. I bought them as Black eyed Susan, and that's all I know. They have grown to about 2 and 1/2 feet high with bright yellow flowers with the distinctive black centre. The only reason for my question is that they are hopelessly out of place where I've planted them, and if I can transplant them, I've now sorted out the ideal spot

[Lazzerelly]

I have asked the question from where I purchased them and they are RUDBECKIA HIRTA, does this help?

Known also as Cone Flower here in the States... you can transplant yet this fall. Pick a nice cool day and dig the plant up with plenty of roots. Maybe 10 inches to a foot away from the main stem and at least 8 to 10 inches deep. Prepare the hole to recieve the plant in the same way... lotsa room. I always line the hole with peat moss... pack the soil back in snugly and water a lot... no standing water, but deffinitely water well.

Don't fertilize this fall... wait until spring else you may encourage new groath this fall and the plant could be dmamged in a cold snap... Good luck!

Thanks very much to all, I will try my ham fisted best to do as advised
