Oleander can grow to be a substantial shrub or tree, reaching heights of 15 to 25 feet tall.

The leaves of an oleander plant are quite large, measuring up to 12 inches long and 1.5 inches across, and are positioned opposite or in whorls of three or four.

Each leaf has a prominent midrib with secondary veins that run parallel to each other all the way to the leaf margin, giving them a distinctive appearance.

Most cultivars will grow to 8 to 12 feet tall and almost as wide. They can spread out quite a bit, making them a great choice for gardens or landscapes that need a bit of width.

In some protected areas, mature plants may reach up to 20 feet tall, giving them a dramatic presence in the garden. This is especially true if you have a spot that gets plenty of sunlight and care.

Some dwarf cultivars stay as low as 3 to 5 feet, making them perfect for smaller spaces or containers. This compact size is great for patios or balconies where space is limited.

Oleander is a highly toxic plant, and its leaves can be lethal to animals if ingested.

As little as 0.005 percent of an animal's body weight of dry leaves can be fatal.

This means that a single leaf can be enough to kill an adult horse, and 10 to 20 medium-sized leaves can be deadly.

Oleander is toxic to all animal species, so it's not just horses that are at risk.

Many livestock and pets are poisoned by oleander clippings or dead leaves, which are often consumed because they're palatable.

Compost containing oleander leaves has also been linked to poisoning, so it's essential to be cautious when handling it.
