I also love morning glories. In many temperate zones they are banned as
invasive because they don't die back. In my zone 5 they act as an annual.

Only certain species of morning glory are invasive, primarily those referred
to as bindweed, Convolvulus arvensis and Calystegia sepium, and are widely
naturalized throughout most of North America. Most of the others are
tropical in origin and act as annuals and are very well-behaved garden
vines. A few are more perennial but only in warmer zones.

There is such a hue and cry about invasives these days (and rightly so, in
many situations) but it is important not to tar all plants with the same
brush. Common names are extremely misleading, as many plants with widely
different habits can be included under the same common name. And not all
invasives will act the same in different climates and locations - invasives
are VERY regional in nature and it is important to make that note when
referring to them.

okay, off my soap box now :-))
