Last fall I collected a handful of seeds from a field of Cutleaf Morning Glory (Merremia dissecta) vines and planted them in my yard. So far, two have sprouted and the larger of them just bloomed.
Unlike their common name, these tend to flower in the middle of the day, adding a cheery pop during the heat. I’m hopeful that these groundcover vines will continue to spread along the outside of my fence. Especially since they are native and won’t require any attention from me.
