Growth Stages

1

Establishment

4-8 weeks

Young plants develop initial rosette of small heart-shaped leaves with visible sheen and burgundy undersides.

Keep soil consistently moist, mulch around base, protect from direct afternoon sun. Do not fertilize heavily; focus on soil moisture.

2

Vegetative Growth

6-12 weeks

Leaf rosette expands significantly; leaves grow larger and more lustrous, with prominent veining and metallic quality becoming more pronounced.

Maintain consistent moisture, apply balanced liquid fertilizer monthly during growing season. Remove any damaged or yellowed leaves.

3

Flowering

2-4 weeks in spring (April-May)

Low, inconspicuous flowers emerge from foliage on short spadix stems, enclosed in pale cream or yellow spathes resembling miniature calla lilies.

Continue regular watering and moisture management. Flowers are secondary to foliage; deadheading not necessary but may redirect energy to leaf growth.

4

Dormancy

12-16 weeks (November-March)

Plant enters dormancy in winter; foliage may die back completely or persist as evergreen in warmer zones. Leaf color and sheen may become less vibrant.

Reduce watering slightly but maintain soil moisture. Do not allow soil to freeze solid. Mulch heavily in colder zones (4-5). No fertilizer needed.

Fun Facts
