Cronquist’s Woodyaster: A Rare Utah Native Worth Protecting
Meet Cronquist’s woodyaster (Xylorhiza cronquistii), a charming little shrub that’s as rare as it is beautiful. This petite perennial brings a touch of wild Utah magic to gardens, but there’s an important conservation story behind those lovely purple blooms.
What Makes Cronquist’s Woodyaster Special
Don’t let the name fool you – this woodyaster isn’t your typical garden flower. This compact shrub typically stays under 1.5 feet tall, though it can occasionally reach up to 3 feet at maturity. Its woody stems support cheerful daisy-like flowers in shades of purple and blue that would make any pollinator swoon.
