PLACEMENT & CULTIVATION
This member of the morning glory family hails from tropical regions and shares morning glory's dislike for cold temperatures, preferring to bask under the warm summer sun. Patience is needed when sowing direct into the garden, for it sulks if exposed to chilly nights. To support its climbing habit, provide a trellis for it to twine upon gracefully. Enjoy the summer blooming vibrant red flowers, each bright spark dabbed with honey-colored centers, which serve as irresistible beacons to bees and hummingbirds. Caution: seeds contain some toxic alkaloids.
About 1" per week, more during especially dry, hot spells. Drought tolerant when fully established.
Slightly acidic to slightly alkaline.
Mix in 2" of compost prior to planting and apply a flower fertilizer at bud set for more abundant blooming. Avoid nitrogen fertilizers that favor foliage growth over flower development.
