Sidalcea malvaflora ssp. virgata

Rose checker mallow is one the showiest summer perennials native to the western part of the state. This ‘wild hollyhock’ decorates meadows and swales from slightly south of Portland to the Rogue Valley in SW Oregon. A low rosette of mallow-esque leaves are glossy. The tall straight 16″ spires of densely arranged hot pink flowers wave in the early summer breeze.(Blooms May-July)  A great cut flower this obvious mallow relative is among our natives that improves under cultivation. And it is rust resistant. Double dig a wide hole to incorporate oxygen in the soil add a handful of all purpose organic fertilizer into the hole and mix with the existing soil. Water regularly and deeply for the first few months. Allow the ground to dry some between irrigation Loved by butterflies and pollinators and actually one of the host plants for the endangered Willamette Valley ‘Fendler’s Blue’ butterfly. Continuously irrigated plants will have successive flushes of bloom. For native rainfall only plants the show is a little shorter. Long lived, resents disturbance. Excellent with Iris tenax, Penstemon kunthii and all Achilleas. Native to clay soils that dry in summer. Oregon native plant.
