Adenium plants, often called Desert Rose or Karoo Rose, are succulent shrubs or small trees known for their distinctive swollen stems and vibrant, trumpet-shaped flowers. These plants are native to semi-arid regions of Africa and the Arabian Peninsula. 

Key Features:

Succulent Nature:

Adeniums store water in their thick, swollen stems and roots, allowing them to survive in dry environments. 

Distinctive Stems:

The swollen base (caudex) is a defining feature, giving the plant a unique, bonsai-like appearance. 

Showy Flowers:

They produce tubular, trumpet-shaped flowers in a variety of colors, including pink, red, white, and purple. 

Leathery Leaves:

Adeniums have smooth, glossy, leathery leaves that are spirally arranged on the branches. 

Slow Growth:

Adeniums are slow growing, making them ideal for indoor or container gardens. 

Varieties:

Adenium obesum:

This is the most common and well-known species, often referred to as the Desert Rose. 

Adenium arabicum:

Another popular variety with broader, rounded leaves and a squatter, more bonsai-like growth form. 

Uses:

Ornamental Plants: Adeniums are popular for their attractive foliage and flowers, adding a touch of exotic beauty to landscapes and interiors. 

Indoor or Outdoor Plants: They can be grown in pots or in the ground in warm climates. 

Bonsai: Their slow growth and distinct caudex make them well-suited for bonsai cultivation.
