The Morning Glory Grandpa Otts, 'Ipomoea tricolor', is a Heirloom variety that is so stunning that it belongs in every old-fashioned garden. The intense, 2 to 4 inch across violet blue flowers, have a vivid, incandescent ruby star on the petals. Grandpa Otts blooms from summer until first frost and will bloom more abundantly during cool weather. The flowers open in the morning and close in the evening.
Grandpa Otts Morning Glory prefers full sun and average ,sandy, well drained soil. Water them frequently so they do not dry out. Morning glories seem to bloom earlier and with more blooms when they are constricted to a pot. Plant in the spring after the last average frost date. Plants started too early are less vigorous than those started later. This excellent vine will cover fences and trellises, grow as ground cover, or hang in large baskets or pots.
