Achira Overview

Leafy perennial herb that grows up to 3m in height with large fleshy leaves arising from edible, underground rhizomes. Attractive bright red to orange flowers are followed by warty seed capsules bearing hard, round, black seeds. Some varieties sterile and without seed.

Common problems with Achira

Achira is generally not bothered by pests or diseases.

    How to harvest Achira

    Both the flowers and the rhizomes can be harvested. The pretty red flowers can be cut for flower arrangements and the rhizomes are edible, both raw and cooked. Ground rhizomes can also be used in baking and are a good source of starch. Pick the leafy shoots while young during the growing season.

    Division

    Divide the root clump in the spring. Each portion must have at least one growing point. Pot up the divisions and grow them on in the greenhouse until they are strong enough to be outside.

    Rhizomes
