Gardeners' Notes:

I was sold the seeds to this as 'Scarlet O'Hara' but after the plant bloomed it was identified by an expert as Crimson Rambler. This plant has generally been easy to grow and took approximately 2 months to flower. The seed was old when I sowed it which has led to the plant and flowers being smaller than expected, I'm hoping this will produce fresh seeds I can use to cultivate more plants for next year, which should be more vigorous.

'Crimson Rambler' has pretty, purplish-red flowers with a white throat. Morning glories are easy to grow from seed, and they usually self-sow.

Soak the seeds overnight before sowing. Sow outdoors after the last frost, 1/8" deep, or start indoors in peat pots 3 weeks before the last frost date.
