Bright crimson flowers cover Lady Doorly's morning glory (Ipomoea horsfalliae) throughout the Chicago winters when grown in a conservatory. This nonhardy perennial morning glory from the West Indies can get really large, making container culture problematic. The glossy leaves are palmate, with the central leaflet much larger than the others. It's hardy from USDA Zones 9 to 13; plant this morning glory in moderately fertile, well-drained soil, and provide a support for the stems to twine around.
