HI,

I am looking for some advice. I have 4 very large containers each with one Scarlet Trumpet vine. The vines are growing up an Trellis that the containers are next too. I planted them about 4 months ago and they are doing very well

I am looking for some other plants that I could plant in the container since that are about 28"in across and 3 feet high and so they look very empty with just the vine. I would love to use something like creeping rosmary that spills out over the side and down the pot, but I have been warnner by my mother in-law that anything other than small perenials will cause problems with the vines root system.

Thoughts on what would grow well together?
