I say put them on, Dennis. Last weekend when I was traveling in western Virginia and spotting Lycoris squamigera here and there, I saw lots of Ipomoea pandurata blooming in fields everywhere. Those big white flowers with their purple centers are really eye-catching. I've always wondered why this plant is not better known in gardens. Jim McKenney Montgomery County, Maryland, USA, USDA zone 7, where I've found it hard to collect good seed of Ipomoea pandurata because the seeds are often eaten by some insect.
