Camassia quamash subsp. walpolei
Camassia quamash subsp. walpolei
Walpole's camas is a rare Oregon-endemic subspecies bearing elegant blue-purple flower spikes ideal for native plant gardens and wet meadow restorations. Plant bulbs in autumn in organically rich, moisture-retentive soil and ensure consistent moisture through the spring blooming period. After foliage yellows and dies back in early summer, bulbs enter dormancy and require little to no supplemental watering.
