Although they are usually very expensive and difficult to find, it can be satisfying to have a garden that consists of some rare and attractive flowers. While most gardens have flowers such as pot marigolds, peonies, salvias and poppies, gardens with desert roses and red ginger flowers are much more unusual.
The desert rose (which is also known as Adenium obesum) is a rare plant that is part of the Apocynaceae family. Desert roses are tender and tropical perennial plants that can grow to heights of between 4 and 6 feet. Their blooms are a vibrant red color. They bloom from the end of the spring up to the start of the summer. The deciduous plant works well when grown under full sun. If ingested, some parts of the desert rose are poisonous.
Allamanda cathartica is part of the Dogbane (Apocynaceae) family. These rare flowers are also known as golden trumpets or simply allamanda. They are compact growing plants have that whorled foliage with deep veins. The leaves are pale to bright green. The flowers are vibrant and yellow. The plant emits a milky type of sap and is toxic. All sections of the plant are cathartic, hence, its name. Allamanda cathartica originates in Brazil and commonly appears in tropical regions all over. They adapt well to most different varieties of soil.
Twin-flowered agave is also called Agave geminiflora. This rare flower grows in a very symmetrical manner, in a perfect rosette shape. Twin-flowered agaves have small, deep green leaves. The leaves are considerably smaller than those of other types of agaves at just a quarter of an inch in width. These plants can be cultivated in both shade and in full sun. When grown in full sun, the leaves of the twin-flowered agave will be still. In shade, the leaves loosen up significantly. The flowers work well in soil that is well-drained and the plants are tolerant of drought. The flowers bloom to a pleasant, light yellow color.
