Mandevilla tendril question
I hope someone can help me. I purchased two sun parasol mandevillas at the same time from the same place this spring. One has tendrils all over the place, the other, not a single one. Does anyone know why? Or how to get a mandevilla to start sprouting tendrils? Im confused. Any help would be appreciated. Everyone I have talked to said that a mandevilla naturally sprouts tendrils. Thank you.
