Overview

Haworthia is a genus containing around 57 species from the Asphodelaceae family. These succulent plants are small, forming rosettes of chunky leaves. They don't tend to have much of a stem and they form clumps. Plants in this genus are very similar, but their leaves can show wide variation, even within a single species. They enjoy well-draining, gritty soil and full sun to partial shade. If growing as a houseplant, place on a bright windowsill and water infrequently when the soil has thoroughly dried out. Haworthia flowers are small, tubular and double-tipped, often with the petals bending backwards away from the flower throat, this is termed reflexes. The flowers are produced on tall inflorescences which grow 4-5 times the height of the leaf rosette. They are popular garden and container plants. Haworthia attenuata and Haworthia cymbiformis are frequently grown indoors as houseplants or outside in mild climates as garden plants.

Common problems

Generally problem free, but are susceptible to root rot if given too much water.

    Companion plants

    Plant with other succulent species that have a similar climatic requirement.

    Harvesting

    Generally not harvested.

    Propagation

    Division

    Divide the offsets when they become too overcrowded. Allow the soil to dry, lift the plants and gently ease the roots apart, then replant. When taking offsets, use a sharp knife or secateurs and cut as close to the mother stem as possible to include as many roots as possible, then allow the offset to dry briefly before repotting it (similar to cuttings from other succulents).

    Cuttings

    Can be propagated from leaves, simply remove cleanly from the mother plant, let callus for a few days until the wound has closed and place on soil or in water and wait for roots to develop. Roots usually grow first to seek out water, followed by new leaves. This may take anywhere from a week to a few months and there is no need to water propagating succulents as they will glean all the nutrition and moisture they require from their mother leaf, which will shrivel up over time. The original leaf may be gently removed once it has dried up and become crispy in texture, only remove if it comes away easily otherwise you risk damaging the baby plant.

    Seed

    Sow seed in spring in sandy soil.

    Special Features

    Pot plant

    Good container plants, place in semi-shaded position and ensure good drainage for best results. May also be grown inside as a houseplant, but requires good levels of sunlight.

    Drought resistant

    Succulent leaves serve as water storage organs.
