Curious rather than beautiful relatives of calla (Zantedeschia), attractive both to children and to fanciers of the odd. Flowers are tiny, crowded on a club-shaped fleshy spike (spadix) surrounded by an overarching flower bract (spathe) that is usually green or dull purple in color and often striped in a contrasting color.
In late spring, tubers send up one to three leaves, each divided into three or more leaflets. Inflorescences appear on a separate stalk in spring or early summer. As flowers fade, spathe withers and spadix forms orange to red seeds.
These are woodland plants, appreciative of organic material in the soil. Plant in fall, setting tubers 1 ft. apart, 2 in. deep. Plants die to the ground in winter; don’t let dormant tubers dry out completely.
From Japan. Grows to 20 in. tall, with 6 in. leaflets. A 4–12-in. stalk supports a 6-in. spathe that is erect rather than arching. Spathe is purplish brown on the outside, yellowish white within; spadix is pure white and expanded at the tip.
This variety has large, pure white, single flowers that last 3–4 days on the bush.
Temperatures below 24°F (–4°C) can cause severe damage. Native to New Zealand. Exceptionally f...
To 2 to 3 in. high and 3 ft. wide, with inch-long leaves and erect, 1 1/2-in. white flowers.
