Clustered, wand-like succulent stems rise vertically in dense thickets, coated with a chalky wax that conserves precious moisture under the baking desert sun. Bright reddish-pink, shoe-shaped floral bracts cluster along the upper stems to lure resident hummingbirds during winter and early spring. The nearly leafless stems perform the bulk of the plant's photosynthesis while exuding a caustic white latex when punctured.

Why interaction risk is high
Milky latex sap irritates skin and eyes and is toxic if ingested; avoid touching broken stems.
Why it is dangerous
Produces caustic milky latex rich in diterpene esters that triggers intense skin blistering, eye inflammation, and severe gastrointestinal distress if swallowed.
How to recognize a risky encounter
Look for dense clusters of erect, chalky-green cylindrical stems topped seasonally by bright red, slipper-shaped cyathia.
What to do
Observe from a short distance and wear protective gloves and glasses if pruning cultivated plants.
Responsible observation
Viewing: Admire the vibrant scarlet blossoms without breaking or handling the succulent stems.
Landscaping: Grow in full sun and well-draining soil to attract desert hummingbirds without irrigation.
