Light Requirements
Sisyrinchium dimorphum requires full sun exposure or partial shade to thrive. In areas with hot summer climates, partial shade may be preferred to protect the plant from excessive heat and dryness.
Temperature Requirements
For optimal growth and development, S. dimorphum requires a temperature range of 60-80°F (15-27°C). This species can tolerate some frost and freezing temperatures, but it is sensitive to extreme cold conditions.
Soil Requirements
The plant prefers well-draining soil that is moist but not waterlogged. The ideal pH range is 5.5-8.5, and the soil should be rich in organic matter. S. dimorphum can tolerate a range of soil types, including sandy, loamy, or clay soils.
Cultivation
Sisyrinchium dimorphum R. Oliver, commonly known as Blue-eyed grass, is a perennial plant that is relatively easy to cultivate. It thrives in well-drained soil and prefers full sun exposure. This plant can grow up to a height of 8 to 12 inches and has a spread of 6 to 10 inches.
To cultivate Sisyrinchium dimorphum, start by clearing the planting area of any weeds or grass. Add organic matter to the soil to improve its fertility and drainage. This plant requires a moderate amount of water and is tolerant of drought once established.
Watering Needs
While Sisyrinchium dimorphum is drought-tolerant, it still requires regular watering until it becomes well-established. Once established, the plant requires watering only when the topsoil feels dry to the touch. Overwatering can lead to root rot and other diseases, so it's always important to water Sisyrinchium dimorphum sparingly.
It's best to water this plant deeply to encourage root development. However, do not let the soil become waterlogged because this can lead to the development of fungal diseases.
Fertilization
Sisyrinchium dimorphum doesn't require heavy feeding but can benefit from a balanced fertilizer application once annually. A slow-release, all-purpose fertilizer is the best option for this plant. Apply the fertilizer in early spring or late winter before the start of the growing season.
It's important not to over-fertilize the plant as this can lead to excessive foliage growth. Instead, stick to the recommended application rate indicated on the fertilizer package.
Pruning
Sisyrinchium dimorphum doesn't require heavy pruning, but you can remove dead or damaged foliage to promote new growth. If you want to contain the size of the plant, you can trim it back after flowering. However, avoid cutting back too much foliage as this can affect the plant's ability to produce flower buds for the next season.
When pruning, always use a sharp, clean pruning tool to avoid damaging the plant. It's also important to sanitize the tool after use to prevent the spread of diseases to other plants.
