I believe it is a rose of Sharon. Large shrub...at least 10' tall 'x6' wide. White flowers..a pink flower or two on same plant every so often.
Smallish leaves on mostly vertical limbs. thanks...Melanie
Definitely not Rose of Sharon (Hibiscus syriacus). I think it's probably a more tropical species (although I don't think it's the "usual" tropical hibiscus H. rosa-sinensis). Can you post some better pictures of the leaves and maybe the whole plant from slightly farther away to show the growth habit?
I have two large of the dainty white. One of which gets a couple pink flowers every so often. It is a very beautiful flower. If I were a fairy...I would wear it as a dress. he...he... Seriously though... I am trying to root cuttings at this time. Gonna keep trying till I get it! So...If i succeed...I will share. M~
