Please can somebody tell me what this plant is? I started growing some
seeds last summer of this plant. They were tiny this time last year but
overwintered in my greenhouse so obviously a hardy perennial. The
person
I got them from could not give me a name. He said the flower is a kind
of spike shooting up in early Summer and it was a very dark purple. He
got the seeds from a park near to where he works. I haven't been able
to find the plant on the 'net'.
I can't identify it, so I'll take Dave Hill's word, but your conclusion
that it is a hardy perennial was unsafe. It could have been a hardy
biennial. Depending on how much protection you greenhouse provides it
could also be a half-hardy biennial or half-hardy perennial.
Digging around the WWW I find that it is hardy to -10C or so. But it is
also described as a half-hardy annual.
