Red Azaleas flowers
Azalea (Rhododendron occidentale sp.) -
Azalea, a bonsai favorite, is the common name for the dwarf type Rhododendrons. Although a low toxicity plant it is best to keep children and pets away. All Rhododendrons should be treated as poisonous. All parts of the plant are poisonous and contain Andromedotoxin and arbutin glucoside - which causes Nausea, salivation, vomiting, weakness, dizziness, difficulty in breathing and loss of balance. 100 to 225 grams of azalea leaves must be eaten to seriously poison a 55 lb (25 kg) child.
