Taxonomic Information

Appearance

Hymenocallis plants have long, strap-like leaves that can grow up to 2 feet long. The flowers are the main attraction, as they are large and showy, with a unique shape that resembles a spider. The flowers have six white, elongated petals that are fused at the base to form a tube. The petals are often frilly or ruffled at the tips, and they surround a central cup with a yellow or greenish throat. The flowers bloom in late spring or early summer and can last for several weeks.

Care Guide

To keep your Hymenocallis plant healthy and thriving, follow these care tips:

• Water: Hymenocallis plants prefer moist soil, so water them regularly, especially during the growing season. However, make sure not to overwater them, as this can lead to root rot.
• Fertilization: Fertilize your Hymenocallis plant every two weeks during the growing season with a balanced fertilizer. Reduce fertilization during the dormant season.
• Soil: Hymenocallis plants prefer well-draining soil that is rich in organic matter. Avoid heavy clay soils.
• Sunlight: Hymenocallis plants prefer partial shade to full sun. However, they can also tolerate full shade, but this may reduce their flowering.
• Hardiness Zones: Hymenocallis plants are hardy in USDA zones 7-11. In colder regions, they can be grown as container plants and brought indoors during the winter.

To prevent fungal diseases, avoid overwatering and ensure good air circulation around the plant.
