Lomatium columbianum

Biscuitroot, Desert-parsley


Add to wishlist Remove from wishlist
One of the wildflower kings of the Columbia Gorge. This is an awesome Desert Parsley that can be found near Lyle on the eastern Washington side of the river growing out of basalt rubble outcrops in the grasslands. Billowing mounds of blue green ferny foliage and big rich pink flower umbels. One of the finest species in the genus and to our minds, one of the most spectacular wildflowers in the State. This has thick deep roots reaching through the tumbled rock into the volcanic clay soil beneath. This endures baking heat and drought in the summer and as a consequence, completes its growth cycle quickly and goes dormant in early summer. Great larger perennial for the rock garden. Young plants not blooming size.
