Please note that the remark in the listing "may be invasive" does not apply to cultivar 'Diana' which is a sterile clone.After 25 yrs in my garden not one single seedling proves it. You may wish to correct the listing. OTHER Hibiscus syriacus can be invasive however not 'Diana'.

Wonderful large luminous blooms! Seems to have a few volunteers here in N Florida, but not excessive by any means - estimate 1 successful seedling a year

I love this Rose of Sharon! Diana is a luminous and has single flowered pure white blossoms. Mine is trimmed into a little standard, and if the japanese beetles don't shred the flowers (they love them as much as I do) then it is pristine. Drought tolerant, loves sun, and it has never seeded around on me, not once!
