Alocasia 'Imperial Red' is a large hybrid Alocasia with broad green leaves, sturdy petioles and red to burgundy tones most visible on the undersides and stems. With enough root room, it can produce larger elephant-ear-style leaves on thicker petioles.
Its parentage is Alocasia odora × Alocasia macrorrhizos 'Pink Petiole'. The cross produces a warm-growing plant with broad blades and upright petioles.
Alocasia 'Imperial Red' was bred by LariAnn Garner of Aroidia Research, using Alocasia odora as one parent and Alocasia macrorrhizos 'Pink Petiole' as the other.
This is a larger-growing Alocasia with broad leaves, strong petioles and a root system that can fill a pot quickly. Give it space above the pot, a stable container and enough clear indirect light to keep the petioles firm. Repot once roots circle the container.
Large active leaves use more water and nutrients than compact jewel-type Alocasia, especially in warm, bright conditions. Water thoroughly, but do not leave the pot sitting wet for days.
Mature Alocasia 'Imperial Red' may produce a spathe and spadix like other aroids. Indoors, it usually holds broad leaves on red-toned petioles rather than flowering.
Alocasia 'Imperial Red' has irritating sap and plant tissue. Keep broad leaves and cut stems away from pets and children, and wash your hands after pruning or division.
The genus name Alocasia refers back to Colocasia, a related aroid genus. 'Imperial Red' points to the red, pink or burgundy tones visible in the petioles and leaf undersides of mature plants.
Give it overhead space; mature plants can build broad leaves on tall, red-toned petioles.
