Ipomoea purpurea 'Kniola's Black'. Probably the most floriferous & easiest to grow of all Morning Glories & long-blooming, too! Rich velvety deep purple 3.5” blooms have luminous bright pink throats. Blooms appear in mass all Summer against lovely deep green heart-shaped leaves. It’ll cover a fence or post in a jiffy & self-sows with ease so you can look forward to it every Summer. Wild & crazy used as a front of bed trailer. To 8’ tall & 5’ across in rich soil with regular water.
