Habit:  herb

Description: 

Genus:  "Herbs, mostly with only radical leaves; rosette-forming.  Flowers in simple or sparsely branched racemes, regular, the peduncle smooth and usually leafless; flowers solitary or in fascicles, on articulate pedicels, 6-parted, stamens 6, inserted on the torus; ovary sessile, glabrous, 3-angled, 3-celled; ovules 2 or more per cell; style filiform, stigma small; fruit a capsule with flat black seeds."

Species:  "Rosette herb with tuberous rhizomes; leaves rather short, about 15 cm long, coriaceous or thinner, flexible, not fleshy, ensiform, the margins white-banded; scape suberect, sometimes with a few leaves; flowers white, 6-parted; fruit a leathery capsule, 3-angled; seeds flat"  (Stone, 1970; p. 114).

"It is a grass-like evergreen, clump-forming, perennial, herbaceous plant growing quickly to 25-35 cm in height and 60-90 cm in width. Planted in and hanging from a basket it can become 60-90 cm long. Roots: It forms thick, fleshy roots and rhizomes. These serve as water storage organs for dry periods. Stems: Wiry stalks up to 1.5 m long appear on healthy plants with many small white flowers. After blooming and fruiting, little tufts of leaves - plantlets - develop on the stalks. These little "spiders" take root wherever they touch the ground. Leaves: It has 10-40 cm long and up to 2.5 cm wide, linear, grass-like. Wild species have green leaves, cultivars often striped yellow or white. Flowers: Small white flowers are borne along outward arching wiry stalks. Fruits: Seed filled capsules about 0.8 cm long." (Ecoport)

Habitat/ecology:  "Latitude: Found between Equator and 30øN in frost free costal areas even a bit further north (40øN).
Temperature: Between 18-24øC during the day and 8-13øC at night are ideal. Move plants a bit away from windows to protect them from drafts during the winter. Reported temperature range for growth is 8-30øC with the optimum between 12-24øC. Plants do not tolerate frost, but can be grown in areas with winter temperatures down to a few degrees below 0 where it will be killed to the ground but quickly revives with the return of warmer temperatures.
Water: It needs moderate but regular watering. Reported annual rainfall range for growth is 500-3000 mm with the optimum between 700-1500 mm.
Radiation:
Range & intensity: Plants grow best with bright indirect light. They can tolerate some direct sunlight, but the combination of midday and afternoon heat and light may scorch leaves.
Soil:
Physical: Low humidity and excessively dry soil may also cause brown leaf tips. Leaf tip burn is caused by too much fertilizer or water that is high in soluble salts. Plants should dry out briefly between waterings. A general-purpose potting soil is suitable for spider plants. Outdoors the plant will however grow in most well drained and somewhat fertile soils.
Chemical: Reported soil pH range for growth is 4.5-7.5 with the optimum between 5-7" (Ecoport)
