Commelina Welwitschii

Description

Commelina welwitschii is an herbaceous plant in the dayflower family found in Southern Africa from Zimbabwe to Angola. A phylogenetic study based on the nuclear ribosomal DNA region 5S NTS and the chloroplast region trnL-trnF, two commonly used gene regions for determining relationships, revealed that Commelina welwitschii forms a clade with Commelina purpurea and Commelina fluviatilis.

Humidity

Average to higher household humidity is best. If the air is too dry, the leaf tips of a Commelina Welwitschii plant turn brown. Place a Commelina Welwitschii plant on a tray of wet pebbles to increase the humidity around it. Be sure the plant is sitting on the pebbles and not in the water.

Light

Commelina Welwitschii plants need very bright light.

Soil

Use a well- aerated soil that drains quickly. If the soil seems heavy and clay-like, add some peat moss and perlite.

Temperature

A Commelina Welwitschii plant grows well in temperatures between 60°- 80°F (15.6°- 26.7°C).

Watering

Water well and then allow the top 2" to 3" of soil to dry out before watering again. If the soil of a Commelina Welwitschii plant stays too dry and the plant is in bright lightVery few houseplants should be placed in direct sun. High light refers only to bright indirect light since direct sun often burns the leaves of indoor houseplants. An area that is too hot and dry encourages Spider Mites and causes blooms to quickly fade. A northern exposure really doesn't provide enough light for high light plants. These plants need to be placed directly in front of an east-facing window, within 1-3 feet of a west-facing window, and within 5 ft. of a south facing window. A high light area has over 300 ft. candles of light., the leaves become stunted and lose color. Over watering causes root rot.

Fertilizing

Feed monthly in the spring and summer with a well balanced plant food diluted to 1/2 the recommended strength.

Propagation

Commelina Welwitschii plants are easily propagated from Stem Cuttings.
