Pure white hibiscus syriacus

Was just wondering whether to buy a Rose of Sharon plant for a shady,dry area here...this would be the common Hypericum with the yellow flower related to your beautiful shrub,Klahanie.

Yes you call Hypericum a Rose of Sharon in England. We call Hypericum "Saint John's wort" here. Complicated.... that is why using the botanical names is most useful in descriptions.
They are not related.
I also have the Hypericum Hidcote you are thinking of getting Julia. Mine is doing well here in a shady and dry area,

That's helpful Klahanie.thank you..there are very few shrubs which grow in those conditions.

Hypericum is also called Saint John’s wort here … quite a spreader, but as you say, useful in shade.

I believe that Julia is talking about the "shrub form" (?) Hypericum, Sheila.
I think Siris also grows it.

Yes, the ground covering Saint John’s wort is aggressive spreader ....I have it in many places also. Once established, it can be difficult to remove .

I do like this Klahanie, a totally white Hibiscus.
Very lovely..

Thank you Janey. I do love white flowers in the garden.

Yes, how they sparkle at dusk!

Yes, I do like the purity of colour. Very luminous too.
