Trillium chloropetalum is variable species with flowers from white and yellow to deep purple.

A spring flowering trillium native to the west and north-west coastal areas of the United States. To 30 – 40 cm.

The foliage is usually, but not always mottled, a deep green and maroon. Flowers are held erect.

These Trilliums are adapted to dry summers, so as long as you can provide some shade, little to no water is required over summer.

Trillium Chloropetalum Care

Care is no different to other Trilliums

  • Dappled shade, or early morning sun and filtered afternoon shade. Very heavy shade will limit flowering.
  • Humus rich moisture retentive soil. However not soggy water logged soils.
  • Try planting beneath deciduous trees, they will get light in winter, filtered light in spring, and then the shade in summer that will keep the rhizomes cool.
  • Ideally the leave litter and subsequent leaf mold will generally be enough to fertilize Trilliums.
  • An application of liquid seaweed fertilizer in spring is beneficial.
