Help Please to ID this Stunner

About 7 years ago I bought a bare root shrub from Spalding Bulb & Plant Company, I potted it up and it grew 3 stems to around 6/7ft in one year and produced several of these amazing huge flowers that were enormous, a good 6-8" across.

The description that I remember at the time was that it was root hardy to around -5, if cut down by frost it would re-grow from the base. I cut it back in the autumn and stored it in a frost free place that wasn't too warm and the following spring it re-grew very easily.

Unfortunately after about 4 years I lost it, I'm pretty sure it was a variety of 'Hibiscus', the leaves were a light to mid-green.

I'd love to track down another one or even seed for it, any ideas???

Thanks in advance

 

Swamp rose mallow?

 

Thanks for that, it looks very, very similar, but there are subtle differences in flower/petal shape, if variation within the variety is normal then this is probably the one???

 

Hi Michael ... it's a Hibiscus Newbiscus which are hardy once established. I've had mine for several years. They are fascinating and I get 50-60 blooms on mine each year. I have only seen the pink ones for sale here but would love a red one. Someone I know on another forum has one but lives in Germany so his never seeds. :(

 

Thanks Victoria; that's the one
