hippeastrum amaryllis care guide

Hippeastrum and Amaryllis are two decorative plants of the Amaryllidaceae family, often used as houseplants. Hippeastrum is known as “knight’s-star-lily” and Amaryllis is known as “belladonna lily”. Both are bulbous species, and the flowers are similar to lilies. Most often they are confused or even considered the same species, but there are some differences that are easy to notice in order to distinguish between the two.

Hippeastrum spp. is a plant native to South America, the leaves appear after flowering, it has hollow flowering stems and can have between 3 and 6 flowers, without scent.

Amaryllis spp. has its origins in South Africa, has no leaves during the entire flowering period, the flowering stems are fleshy and have between 6 and 12 flowers. Unlike the flowers of Hippeastrum, Amaryllis has fragrant flowers.

Species and varieties. The genus Hippeastrum has a relatively large number of species (over 90), with colorful flowers in various shades of pink, orange, or red, but there are also hybrids with white flowers. Of these species, the most common are:

  • Hippeastrum vittatum – it has white flowers.
  • Hippeastrum rutilum – it has red flowers.
  • Hippeastrum puniceum – it has orange flowers.

The genus Amaryllis has a single species, Amaryllis belladonna, with pink flowers.

The two species have similar requirements to environmental conditions.

Care. During the growth and flowering period (spring-summer), watering can be done abundantly, but it is recommended to remove the water from the tray a few minutes after watering. Water stagnation at the roots can lead to bulb rot. Before you water it again, the substrate should be allowed to dry.

Fertilization. in the spring-summer period, fertilization can be done monthly with a special fertilizer for decorative houseplants (through flowers). Starting with September, the fertilization should stop and the watering has to be reduced in order to favor the entry of the plants in the dormancy period.
