Ipomoea hederifolia lutea - Yellow Morning Glory
This tiny yellow morning glory is quite rare, but is as enthusiastic as its common cousins. Butter-yellow trumpets the size of a quarter bloom in clusters among heart shaped leaves. They stay open from morning till well past sunset.
The annual vines grow quickly to 10' and will cover a fence or trellis in no time. Yellow Morning Glory is vigorous and easy to grow. It does need a trellis or it will climb whatever is handy.
Hummingbirds and butterflies love this vine!
