I used to think the hibiscus i was growing had a problem but it turns out there is a type of hibiscus that never opens! yes i was disappointed because i really wanted it to open but i'm extremely relieved that it's not anything i'm doing :).
I honestly didn't mean for this to be an all about hibiscus blog LOL hope you guys find this helpful in some way...
Common name: Sleeping hibiscus, Turk's Cap, Firecracker Hibiscus
Botanical name: Malvaviscus arboreus var. arboreus Family: Malvaceae (Mallow family)
Its called sleeping hibiscus by some because its flowers look like unopend hibiscus
