A: I’m seeing Asiatic jasmine, Trachelospermum asiaticum, used more and more as a dense and successful ground cover around town. It’s not the same as Confederate jasmine, Trachelospermum jasminoides. Despite the name, neither one is a true jasmine. Asiatic jasmine stems are more woody than Confederate jasmine’s. It’s less likely to climb an arbor unassisted but it covers the ground densely. I’ve never noticed it blooming while on the ground, probably due to yearly pruning, but a neighbor has the vine on a foot-tall fence and it blooms fragrantly and reliably each year. Asiatic jasmine tolerates a bit of foot traffic. It is tough, deer-proof and readily available. To keep it neat, use shears or a string trimmer to cut it down to 6 inches in early spring each year.
Q: Several years ago, we planted asparagus crowns in a bed where they thrived. But six years ago, they started producing small stalks with only ferny foliage. Could it be that the crowns have gone too deep? Will Magruder, email
