Pseudotrillium rivale syn. Trillium rivale


Add to wishlist Remove from wishlist
This sweet little Trillium from the Siskiyou Mountains has been moved into its own genus of which it is the sole representative. This is known as a monotypic genus and we are drawn to such isolated species. This is quite diminutive but is very beautiful with usually white flowers but can be pink or have varying degrees of dark pink spotting. It increases well by division - these are nice freshly divided plants.
