Royal Jacob’s ladder has sweet, open, bell-shaped flower clusters that bloom in early summer in shades of peach, pink, white or pale lavender. The pink flower color has led to the additional common name, salmon polemonium, but Oregon polemonium or royal sky pilot are also sometimes used. Royal Jacob’s ladder is a clumping, rhizomatous perennial wildflower with green compound leaves that grows up to 30″ tall. It’s range extends from Washington state down to the San Francisco Bay area of California west of the Cascade Mountains. It is common in Oregon and Washington, but rare in California. Royal Jacob’s ladder can be found growing in a wide range of habitat conditions, such as woody thickets, upland prairies, moist or dry forest openings, open meadows, and mixed conifer forests, generally at low to mid elevation. It prefers medium soil moisture with good drainage, and full sun to part shade. The flowers are attractive to a wide range of pollinator species.

Royal Jacob’s ladder (Polemonium carneum) seed packets contain approximately 60 seeds per packet.
