We visited Moody Gardens on our trip through Texas. There were so many plants that i loved there. I wanted to take cuttings!!! I got my Rangoon Creeper off e bay. I got 2 and put them in a pot together. They will have to winter in the house. The plants were in very nice shape and fully rooted. They almost needed to be moved up a pot size.
Now I called Moody Gardens for help but no one got back to me. I would like to know the name of this tree and were and how to get one. I think I cangrow it here in a large pot.
Thanking everyone in advance for everyone's help.
My oleander cuttings have rooted.I won't know till spring what I have most looked like a beautiful florescence pink, double I think. They had so many beautiful ones but the humidity was just too much to walk around very much.
