Propagation of Alternanthera tenella Colla var. versicolor (Lem.) Veldkamp
Alternanthera tenella Colla var. versicolor (Lem.) Veldkamp, commonly referred to as Calico-plant, is a herbaceous plant that is native to South America and is widely cultivated across the world. Propagation of this plant can be done through the following methods:
Seed Propagation
Alternanthera tenella Colla var. versicolor can be propagated through seeds. The seeds of this plant are easy to collect from their flowers, which are produced throughout the summer. The seeds can then be sown directly into pots or the ground, from late winter to early autumn.
Before sowing the seeds, the soil should be moistened, and the seeds may be gently pressed into the soil. They should then be covered with a thin layer of soil and watered lightly. The seeds should start to germinate in about two to four weeks, after which they can be transplanted to their permanent location or container.
Stem Cuttings Propagation
Alternanthera tenella Colla var. versicolor can also be propagated from stem cuttings. The stem cuttings should be taken from healthy, non-flowering shoots of the plant and should be about 5-10cm long.
The lower two-thirds of the cutting should be dipped into a rooting hormone solution before planting. After this, the cuttings should be planted in a moist potting mix or directly in the ground, about 2-3cm deep. The soil should be kept moist, but not waterlogged, and the cuttings should be kept in a warm, bright location out of direct sunlight.
Roots should start to form in about a month, after which the cuttings can be transplanted to their final location or container.
Division Propagation
Finally, Alternanthera tenella Colla var. versicolor can be propagated through division. This method is ideal for plants that have become too large for their container or have lost their shape.
The plant should be carefully removed from its container or the ground, and the roots gently separated. Each division should have a healthy root system and a few leaves. The divisions should then be replanted in pots or the ground, after which they should be watered lightly. The plant should be kept in a warm, bright location out of direct sunlight, and the soil should be kept moist until new growth begins to emerge.
