Lespedeza is one of my favorite plants partly because of its old fashion name “kissing by the garden gate”. You get a lot of bang for your buck with this $12.00 perennial that starts out the size of your hand and grows bigger than you in 3 years. The pretty pink flowers are shaped like a pea bloom and lasts for months. The only maintenance is to cut the plant with hedge clippers in June, and then again in February.
Silver Fleece Vine
This is another inexpensive perennial that grows quickly and holds well to pergolas and other upright garden features. It isn’t that terrific while not in bloom, but is just great in the fall when you need something pristine looking that hasn’t been fried by summer heat. When it gets too big after 4 years or so, I cut it back drastically and let it start over again.
