Cheerful, bright yellow, open star-like flowers above clumps of sword-shaped, grey-green leaves. This semi-evergreen, summer-flowering perennial is perfect for a sunny, rock or gravel garden. Best planted in neutral to slightly alkaline soil, Sisyrinchium californicum is short-lived but self-seeds freely.
Please note, we offer this plant in aquatic pots (for submergence in water) and 9cm pots with our peat-free compost more suitable for planting above the water line in boggy soils.

How to care for Sisyrinchium californicum:
These plants are available potted up (using a suitable aquatic compost) into aquatic pots. These pots are made of a fine mesh, which allows water to circulate through the compost, providing the plants with both oxygen and nutrients. If you are using them as a aquatic plant, they can be planted up to a water covering of 5cm (2") deep. For planting above the waterline, choose our 9cm pots for planting in boggy, reliably damp soils. Remove dead or spent clumps every few years to make way for self-seeded plants to develop.

This pond plant is semi-evergreen, so it can lose some of its foliage in winter. In colder regions or more exposed gardens, it may lose it all, but then fresh new growth appears again in spring.
