Oleander
Oleander is a fast-growing shrub with attractive pink, red, or white flowers. It is sometimes grown indoors in bright light or on patios. Every part of the plant, including dried leaves and flowers, contains cardiac glycosides that interfere with heart function.
Pets that ingest oleander can develop vomiting, diarrhea, and life-threatening heart arrhythmias within hours. This plant is best avoided entirely in homes with pets. Choose non-toxic flowering plants such as orchids or African violets instead.
