Spotted this while walking through my neighborhood the other day. A Morning Glory and a Scarlet Trumpet Vine (Distictis buccinatoria) growing together on a trellis.
I’ve never grown a Morning Glory vine, but Sunset has some good information here.
Trumpet Vine is easy. Hummingbirds love it and it grows like crazy- as in 30 vigorous feet of crazy. It flowers all summer and early fall. You need to support it but you don’t need to tie it. Give it full sun. After its first growing season it doesn’t need much water – once a week, tops. To keep it under control, you can cut it back hard after it flowers.
