features
Fern asparagus is a dioecious, evergreen, perennial, herbaceous plant that reaches heights of 50 to 70 (rarely up to 150) centimeters and possibly forms a rhizome . The stem is angular and upright. The branches are arranged in horizontal planes, which makes the plant look like a fern. The dummy leaves are flat, curved and measure 6 to 20 × 0.8 to 2 millimeters. They are arranged in 2 to 8 at the node. The scale leaves are hardened at the bottom, but not thorny. There are usually 1 to 3 flowers per node. The inflorescence is 2 to 3 millimeters long, the flower stalk 1 to 2 centimeters. The berries are 5 to 6 millimeters in diameter and black-green.
The flowering period extends from August to September.
The number of chromosomes is 2n = 16, 18 or 20.
