Oplismenus short-haired (Oplismenus hirtellus) is a herbaceous perennial with creeping, branching and rooting shoots from the family of cereals (Gramineae).

Leaves are elongated-lanceolate, 5-10 cm long, 2 cm wide, flowers are inconspicuous, in paniculate inflorescences formed on upright or rising flower-bearing shoots.

Cultivate a more decorative garden form with white and pink striped leaves.

Short-haired Oplismenus grows well in bright light and in partial shade. Winter temperature is 17-24 °.

Substrate: turf, leafy soil, humus (1: 4: 2).

Propagated by apical cuttings or parts of the shoot with one or two leaves.

The rooted cuttings of oplismenus are planted several pieces in a pot and used in the interior as an ampel plant.

Old specimens quickly lose their decorativeness, so they need to be renewed annually from cuttings.

It is better not to fertilize the variegated garden form, because during overfeeding, its pink and white color disappears.

In the winter garden, Oplismenus is used as a groundcover.

WateringOplismenus: Watering is carried out as the earthen coma dries, abundant in summer, and moderate in winter.

BreedingOplismenus: Easy to propagate by cuttings at any time of the year. After rooting, they are planted several pieces in one pot.

Air humidity: It is useful to spray leaves periodically.

TransferOplismenusA transplant is usually not needed. Adult specimens grow and lose their decorativeness, so the plant is recommended to be renewed every 1-2 years. You can also rejuvenate the plant by pruning in early spring. Soil: turfy soil, humus, peat, sand (1: 1: 1: 1).

Top dressingOplismenus: In spring and summer it is necessary to feed with full mineral fertilizer. When growing variegated forms, fertilize should be moderated, since a pink and white color disappears from an overdose of fertilizers.
