Each year I add another vine or two from the morning glory genus to the gardens' Spring-to-frost display. There are so many choices that look nothing like this genus's heart-leaved namesake. What they do have in common is boundless vigor and floriferousness, plus a complete lack of acrophobia.
This is cardinal climber (Ipomoea x multifida), a hybrid of two red-flowered species, cypress vine (Ipomoea quamoclit) and red morning glory (Ipomoea coccinea). It has raced to the top of a tuteur that I had made "only" fourteen feet tall. Silly me!
