You forgot to tell me (everyone else probably knows!) what they are. I think the last is an anthurium? I didn't know they got that big! Mine are only in 6 inch pots!
The first is a White Bird of Paradise. Second is some type of Jasmine. (maybe somebody can help me out) And I think the third is a caladium. It was included in a plant array that my mom sent me for my birthday last August. The first plant I've been able to keep alive for more than a month. And what prompted me to buy the others.
That BOP is beautiful. I have never seen one before except on the net.
My aunt has a jasmine (don't know what kind) and it smells so beautiful. She is planning on training it up a garden trellis that my hubby and I bought her for planning our wedding.
The third looked like an anthurium to me. See what I mean about not knowing anything?
