Propagation of Convolvulus sagittatus Thunb. var. linearifolius
Convolvulus sagittatus Thunb. var. linearifolius (Hallier f.) Baker & C.H.Wright ex A.Meeuse, commonly known as arrowleaf bindweed, is a herbaceous perennial plant that belongs to the Convolvulaceae family. It is native to Southern Africa and is widespread in arid regions. This plant has arrow-shaped leaves and produces trumpet-shaped white or pink flowers. It grows up to 1m tall and spreads rapidly through its underground rhizomes.
Convolvulus sagittatus Thunb. var. linearifolius can be propagated by both seed and vegetative methods.
Propagation by seed
The plant produces seeds in a capsule that splits open when mature, releasing the seeds. The seeds of Convolvulus sagittatus Thunb. var. linearifolius can be sown directly into the ground in the spring or fall, depending on the climate. The seeds can be lightly covered with soil or left on the surface, as they require light to germinate. The soil should be well-draining and kept moist until the seedlings emerge. Once the seedlings have developed a few leaves, they can be transplanted into their permanent location.
Propagation by division
Convolvulus sagittatus Thunb. var. linearifolius can also be propagated by division. This method is best done in the spring, just as new growth begins. The plant can be dug out carefully, taking care not to damage the roots. The root system can then be divided, ensuring that each division has a good root system and some foliage. The divisions can then be planted in their permanent location, with adequate water provided until they become established.
