Varieties and Flowers

Adenium (Desert Rose) based on its origin and abundance are classified as these species.

1. Adenium (Desert Rose) Obesum

Adenium Obesum is the most popular variety in the family. It is a native of African Sub-Saharan region and grows abundantly in tropical climate regions. Obesum usually grows straight upwards with a greenish grey trunk with fat caudex and gets slimmer on the top and branches.

The plant can be identified with the droplet shape of the leaves and its spiral arrangement. The leaves will be larger in the bottom and the top leaves never cover the lower ones. If kept in hot and humid conditions, obesum blooms in the summer and the flowers will be dark red on the outside and white or light yellow inside. As the flower ages, the dark red will diminish and become light pink.

2. Adenium (Desert Rose) Arabicum

Arabicum is the native or local species found in Saudi Arabia and Yemen. It is known as the most succulent and desert variety. The arabicum varieties can be identified by its characteristic strong fat caudex and squat form and leaves that grow short and concentrated near the top.

The flowers are usually single petals and pink. Unlike obesum the leaves are shiny at the top and bottom surfaces. The flowering season for arabicum is usually from spring to end of summer.

3. Adenium (Desert Rose) Boehmianum

Boehmianum is found growing in abundance in Southern Africa and it is identified for the first time in Namibia. It is characterized by its small size and silvery branching caudex with Pale grayish Green leaves at the end.

The Boehmianum is less popular among Desert Rose lovers due to its relatively poor flowering characteristics and long dormancy period during winter. It shreds almost all the leaves and becomes dormant during the winter.

4. Adenium (Desert Rose) Multiflorum

Multiflorum varieties are commonly called Impala Lily. It is a short variety of Adenium (Desert Rose) species. Multiflorum generally reaches a maximum height of three meters. The plant is characterized by its large underground root and thick smooth branches.

The Multiflorum varieties can also be identified by its leathery, leaves with smooth and shiny green upper side and light bottom side. These species are sensitive to minimum temperatures. A minimum temperature of 10 degree celsius is required for optimal growth. Multiflorum varieties usually bloom near winter with strong red near the edges and fading pink to the center.

5. Adenium (Desert Rose) Oleifolium

This small and very slow growing species is a native of South Africa and Namibia. The Oleifolim is characterized by its sunken caudex below soil extending under a foot in length. They are recognizable by long, very narrow leaves with greenish grey color and a powdery dust can be found on the surface.

Flowering season will start in late spring with relatively small flowers and colors ranging from pink to red. They usually have a range of colors but unfortunately these varieties of adenium are very rare and hard to find.

6. Dorset Horn Adenium (DHA, Dwarf with Curly Leaves

Adenium (Desert Rose) Care

Adeniums are easy to maintain plants as long as you know how it will behave in each season of the year. They will act as two different plants with different requirements during different seasons of the year. During summer, with the warm and humid conditions, they are in full growth period and should be treated as a tropical plant. In a full grown period they need water and fertilisers in abundance. Although during winter, they should be treated as a dormant plant with the least requirement of water and fertilisers.

During dormancy adenium should be potted in a well drained pot with little or no watering. The watering, if needed, can be restricted only to warm bright days during winter or rain. Over watering and poor drainage during dormancy will lead to root rot and that can kill the plant eventually. The potting mixture for adenium should be chosen so that maximum drainage is available.

Potting Mixture

You can start with any light mix available in the market compounded with 30 to 50% drainage material like sand, clean poultry grip, gravel or perlite. The potting mixture needed to be changed every one or two years to restore nutrient balance and soil properties. Choose any kind of pot with good drainage to plant and choose a pot size only a bit larger than the root size. A very large pot with a lot of soil around will cause water retention and thus root rot. We prefer a relatively shallow, bowl-like pot slightly larger than the root system which allows rapid drying and also provides room for root expansion.
