The desert rose can survive for hundreds of years. It blooms twice, first in the spring and the second in late summer or early fall. Spring is the best time to plant seeds or dried shoots. Seed germination takes one week and the seedling will have about six leaves after a month. The garden rose will usually flower the first year it is planted. As for dried shoots, roots will start to grow in six to eight weeks.
The desert rose comes in hundreds of different hybrid varieties. For example, the Apollo desert rose's flower is a mix of black and bright red, and the Star of Luck variety looks like a lily. Many hybrid varieties are grown in Thailand and imported to the United States.
The desert rose grows best in USDA zones 11-12. The plant requires full sunlight and is tolerant of heat. The soil must be well-draining as root and stem rot is a common disease. It is recommended to fertilize the plants every two weeks during the spring, especially when the plants are young. Water regularly during the spring, but keep the soil dry during the winter. Avoid oil-based pesticides to kill common pests such as mealybugs and mites.
The desert rose is a member of the Apocynaceae family and originated in East Africa and southwestern Arabian peninsula. The desert rose is a succulent shrub with pachycaul (thick) stems, glossy green leaves and smooth grayish branches. It can potentially grow to be 6 feet tall.
The shrub's flowers are salverform just like the oleander. This means that the flower pedals are tubular with a flared end. The flowers grow in clusters. The plant reproduces best by grafting as pollination is not highly successful.
