Scoliopus is a rare relative of Trillium confined to the Redwood forests of the western USA. One species in California, one in Oregon.
In the garden they thrive in Trillium conditions, light- or part-shade in a humus-rich, moist yet well-drained soil. Fully hardy here and trouble-free, they like to be left alone to establish and clump up, without disturbance.
We try to list these in late autumn as soon as they are dormant but growth starts again VERY early in our climate and plants despatched after December will be in growth and may even have flowered.
Ordering possible from both Autumn and Spring lists.
