Field notes: Sulphur Flower is very common. They can be found
in flower colors ranging from white, yellow, pale pink to pale
red. I've seen Sulphur Flower turn nearly blood red when the
flowers have matured. Look for Sulphur Flower in any dry, sunny
area from the foothills to the subalpine ecosystems.
Flower is very drought tolerant making them an excellent candidate
for the xeriscape or wildflower gardens.
