Hibiscus Cannabinus

I keep see this variety of annual hibiscus sold as seeds ,
my question is : will it flower ????

anyone tried?

 

Blimey those leaves would fool a few young lads

No idea Sal, do you mean are they male and female plants?

 

Sal - I have no idea. Its not in my small book on Hibiscus - so I can only Google the same sites as you. It sounds similar to H. coccinea though it comes from Asia and not the USA. H. coccinea also grows to 6 foot, is sold as an annual but is really a perennial, and also has cannabis like leaves. Pete has grown H. coccinea and said that it is unlikely to flower outside of a greenhouse. I grew some this year, but they didn't flower or even get to 6 feet. But hopefully they will come back, after overwintering inside, later this year for another go.

Based on that very flimsy evidence, I suspect H. cannabinus is more likely to flower in a greenhouse. Google says they are self fertile - so in theory you could get some seeds from a single plant.

I have got several species of Hibiscus on the go, without much success yet. And this year I have got some Gospium herbaceum seeds (also known as cotton) which is a close relative.
