description for "Morning Glory: Ipomoea tricolor 'Grandpa Ott's'"

‘Grandpa Ott’s’ morning glory, a free-blooming American heirloom, has twining vines with heart-shaped foliage that quickly forms a romantic leafy canopy. ‘Grandpa Ott’s’ velvety, intensely purple flowers are subtly accented with a wine-red star and make a vivid garden display. These seeds have been lovingly tended for years by Grandpa Ott’s family and the Seed Savers Exchange. Very early to bloom, the vigorous vines blossom with glorious abandon throughout the season. The trumpet-shaped flowers always attract and satisfy many hungry hummingbirds. Morning glory seeds have a very hard outer shell. To improve and significantly hasten their germination rate, it is worth the extra effort to use a nail clipper and nick each one just enough to break the seed shell so soil moisture can enter more easily. Alternatively, you can rough these hard-skinned seeds with a file. At planting time, erect well-anchored supports at least 8 feet tall. Morning glories bloom abundantly beginning in mid to late summer once days begin to shorten. Combine with climbing ‘Moonlight’ nasturtiums or purple hyacinth beans for a striking show of iridescent beauty.
