Hibiscus syriacus is a misnomer; the wild range of the species is Korea
(where it's the national flower) and northern China. But it's
naturalised in quite a few warmer places. It comes from a more
continental climate, and according to the literature, requires the aid
of a wall to encourage flowering in the cooler-summered parts of the
British Isles. As it's very late into leaf I assume that it doesn't mind
cold springs.

Dammit - I shouldn't have assumed that "syriacus" meant "well, I first
saw it it growing from some miscellaneous seeds sent from a collector
who had been visiting Syria". Stupid of me :-)

At least it is better than Bermuda buttercup.

It doesn't. It grew successfully here for many years (and other
people grow it), until it succumbed to a fungus or similar. But it
really can't be bothered to wake up until the weather warms up, which
it hasn't done for more than the odd day this year.
