Difference Between Amaryllis and Hippeastrum - Comparison Summary

What is Amaryllis

The Amaryllis is a beautiful flowering plant that belongs to a small genus with only two species, the most famous being Amaryllis belladonna. This species is native to the Western Cape of South Africa, especially in rocky areas of the southwest. Botanists long debated the names of this plant and a similar-looking genus called Hippeastrum. This is why “amaryllis” is commonly used for both plants, especially the ones sold in winter for indoor blooming.

Amaryllis

The plant is also known by many names, like Belladonna lily, Jersey lily, Naked Lady, and March lily. Despite being called a lily, it’s only distantly related to true lilies.

Amaryllis plants grow from bulbs, which are 5–10 cm wide and produce long, strap-like green leaves that can reach up to 50 cm. Each bulb sends up one or two tall, leafless stems, which can hold clusters of two to twelve trumpet-shaped flowers. These flowers, usually white with crimson veins, can also appear in pink or purple.

What is Hippeastrum

Hippeastrum is a genus of flowering plants that includes around 90 species and over 600 hybrids and cultivars. These plants are native to tropical and subtropical areas of the Americas. Hippeastrumplants are best known for their large, striking flowers in shades of red and purple. They’re often mistaken for Amaryllis due to their similar appearance.

Hippeastrum

The Hippeastrum has large, fleshy bulbs, roughly the size of a softball, covered by a protective outer layer with inner scales that help store water. Each bulb produces two to seven long, strap-like leaves that are usually evergreen. The leaves can grow up to 90 cm long and have a simple structure, emerging directly from the bulb and often appearing after the plant has flowered.

The flowers of Hippeastrum grow in clusters, typically with two to fourteen blooms per stem. These blooms appear on a tall, hollow stem called a scape, which can reach up to 75 cm in height. The flowers themselves are funnel-shaped, often curving slightly downward before arching up at the tips. Each flower can be as wide as 20 cm and features six brightly colored petal-like segments called tepals, which are typically red or purple.
