Azaleas contain grayanotoxins that interfere with nerve and heart cell signaling. Ingestion may cause vomiting, drooling, weakness, tremors, abnormal heart rhythms, and collapse. Keep all plant parts — leaves, flowers, stems, and nectar — out of reach, and contact a veterinarian immediately if ingestion is suspected.
Azaleas are ornamental rhododendron shrubs with small, leathery leaves and funnel-shaped blooms in spring. Bloom colors range from white and pink to red and purple.
Azaleas are planted as foundation shrubs, low hedges, and potted arrangements and are common around homes, sidewalks, and apartment complexes. Florist azaleas are sold indoors around holidays and spring events.
Fallen blooms and leaves collect under shrubs after wind or pruning. Clippings may remain in mulch beds, yard-waste bins, or compost piles. Potted plants placed on porches or entry tables put leaves and flowers at pet nose level.
