Anyone know what this vine is? Very tiny toothed leaves and tiny little reddish-pink (or pinkish-red??
) trumpet shaped flowers with a paler throat. This is growing at the Houston Zoo, hanging down over a tall "rock" wall. It was hanging down maybe about 6 feet in total length in full sun. Not clinging in any way and doesn't appear to have the ability to cling - just hang or drape. Stems are very straight and slightly stiff. Stems were also somewhat more angular than rounded.
Thanks!
