My camera is out of action at the mo but I've found some flowers and don't
know what they are, they were growing through cracks in the paving under
last year's hanging baskets were at my local pub and I think they've seeded
from this.

They're about a foot tall, with mixed coloured flowers, the leaves are
pointy and thin almost like grass, the leaves are about an inch long, the
stems seem woody and sturdy, not floppy or succulent if that makes sense.
The flowers look like antirrhinum but I've googled for flowers similar to
antirrhinum and/or snapdragons and had no success.
They don't have masses of flowers just a few unlike antirrhinum, most of
them are purple, but some are yellow and one is yellow and pink on the same
bloom.
I've rescued them and they are now sitting in pots of compost in my
greenhouse, I'll put them in the front garden when they pick up a bit and
then in autumn I'll collect seeds now that I know they are viable and next
year hopeully grow a load for family and freinds, but obviously it would be
nice to have a name, anyone any pointers?
