The angel trumpet plant is a broadleaf evergreen shrub that has a tropical appearance. The plant is native to areas in South and Central America and is hardy to grow in southern areas of the United States. Angel trumpet is appealing for home gardens as it produces large flower blooms, but all parts of the plant are poisonous and should be planted with caution.
The angel trumpet plant is a semi-woody shrub that reaches a height up to 15 feet. The shrub has a single trunk with many support branches. Angel trumpet produces large oval shaped leaves with eye-appealing trumpet shaped flowers that hang down from the plant. The flowers are fragrant and reach 12 inches in length. Most varieties of the angel trumpet have white flowers, but yellow and pink can sometimes be found.
The angel trumpet is hardy to plant in USDA growing zones 8 through 12. The plant does not reach the full height of 15 feet in zones 8 and 9 as it will die back during the winter months and resprout in the spring. Angel trumpet grows best when planted in a well-draining soil that is in full sunlight. The plant will grow in partial sunlight but will produce fewer blooms. Organic mulch or peat moss should be worked into the soil at the time of planting to increase the nutrient value and water-draining ability.
Care and Maintenance
The angel trumpet plant is considered drought tolerant but has better flower production when provided with a moist soil throughout the growing season. Provide supplemental water to the plant when the weekly rainfall amount is less than 1 inch. Fertilize the angel trumpet with a complete or potassium rich fertilizer before the blooming period. Do not use a high-nitrogen fertilizer because this will only promote foliage growth, not flower production. Place organic mulch around the base of the shrub and over the root ball to assist with moisture retention during the hot summer months.
The angel trumpet plant can be propagated to produce additional plants by collecting the seeds that form after the blooming period. Let the seeds dry and place them in a paper envelope until planting time. Sow the seeds indoors in late winter or directly into the soil when there is no risk of frost in USDA growing zone 10 through 12.
Monitor the angel trumpet plant to catch an infestation of spider mites, white flies or aphids. An infestation can be treated by using a hose to spray the bugs from the plant. Apply an insecticidal soap spray to the plant to prevent the insects from returning.
