Vines and Climbers: My Kniola MG needs companion, 0 by MsHansen

For the last three years, I have had a bunch of Kniola's Black Knight in a large pot at my front door. I love them dearly and save the seeds to plant next year, but... They really need a companion. A companion that blooms all day, that is.

My front door patio faces east, i.e. lots of sun in the morning (from 4am), but none in the afternoon. Last year I tried a couple of Mt. Fuji's as someone told me the would stay open longer than the ordinary MG's, but they did not thrive at all. Too little sun, I guess. Same thing with the moonflower from the year before that.

Any suggestions? My MG is a velvety dark purple.

Oh, and it needs to be an annual! We have freezing winters here, so unless it's something I can cut the stems of and store inside (a tuber or whatnot), it's not possible to overwinter,
