Some hardy hibiscus

A few of the named hardy hibiscus I've been trying out and using in crosses.
I didn't have a tag on this one when I got it, but I'm pretty sure that it's 'Fireball'

 

 Here's 'Kopper King'

A new one for me this year, 'Midnight Marvel' - sadly the sawfly larvae really like this one's foliage

'Old Yella' with it's voluptuous flowers

And another even more voluptuous one I got last summer, 'Razzberry Jam'. I like how compact of a grower this one seems to be.
