The leaves of tamarisk are fine-textured and closely resemble juniper foliage. They are compound, alternate, and scale-like, tightly overlapping along the stem. Lanceolate in shape, these leaves have sharp to tapered tips. Each leaf measures up to 0.2 inches (5 mm) in length, presenting a delicate yet compact appearance. The color is a vibrant green, contributing to the feathery look of the foliage. The texture is smooth, lacking prominent veins.

Tamarisk produces striking pink, feathery racemes organized into dense spike-like plumes. These elegant clusters bloom in the spring and summer on new wood, presenting a soft, airy appearance. The tiny individual flowers within the racemes, though small, create an overall bold impact. Each plume can reach up to 4-6 inches (10-15 cm) in length. The flowers are characterized by their delicate pink hue and lack a pronounced scent, making them easily recognizable and a visual delight in their blooming season.

The stem of tamarisk is characterized by its slender, arching branchlets which are light red or orange-yellow and tend to weep when young. As the plant matures, the bark transitions to a grey color. The branchlets are typically thin, measuring around 1/8 inch (3 mm) in diameter, with a smooth texture when young, becoming slightly rougher with age. The overall appearance of the stems is delicate and graceful, enhancing the plant's ornamental appeal.

The fruit of tamarisk is a small, dry capsule which exhibits a distinctive splitting action when mature. These capsules are generally round to oblong in shape, with a surface that may vary from smooth to slightly textured. Upon reaching maturity, the capsule bursts open to release numerous tiny seeds. Each seed is typically surrounded by a tuft of fine hairs, aiding in their dispersal by wind. The color of the capsule is typically brown to grey, blending with the plant's foliage. The size of the capsules usually remains under 1 inch (2.54 cm) in length.
