Porta-copos Blue Flax Seamless Pattern

My paintings of a blue flax blossom, native to western North America from Alaska south to Baja California, and from the Pacific Coast east to the Mississippi River, in a seamless pattern. It grows on ridges and dry slopes, from sea level in the north up to 3000 m altitude in the south of the species' range. I find a lot of these around my home in the Colorado Rockies.
