- Description
-
This herbaceous perennial is commonly grown as a houseplant. Evergreen tropical perennial shrub to 150 cm, erect and bushy. It resembles dumb cane (Dieffenbachia). It has elliptic dark green lance-shaped leaves that reach 4-8" long and 2-3" wide. Attractive silver-gray blotches appear on upright stems. Blooms rarely as a houseplant in the late summer or early fall with a white spadix and green spathe. Red clusters of berries follow the blooms. Does well in in diffuse sun or good indirect light. Prefers high humidity but will tolerate dryer air. Keep the potting mix moist from spring to fall. Does not require a winter dormancy period but prefers a reduction in watering during the winter.
Desired for its erect, green leaves variegated with yellow/cream; tendency to get leggy with age as stem grows, gets cane-like and bends over; excellent plant for low light situations such as exist in most homes; used as filler, or low hedge. Prefers low to medium light, moist soil and medium relative humidity; intolerant of constantly wet soil and of direct sunlight; some pest/disease problems.
Insects, Diseases, and Other Plant Problems: There are not serious disease or insect problems but watch for aphids, mealybugs, spider mites, or scale. Root rots can occur with over-watering. Leaves may turn brown in very dry air or drafty location.
Quick ID Hints:
- Stem present, becoming sugarcane-like with age
- Lanceolate leaves are green variegated with yellow/cream, grey, or pink/red
- Leaves contain 5-8 main lateral veins
- Inflorescence is greenish-white spadix/spathe
Distinguished from Dieffenbachia by a tendency to have only 5-8 main lateral veins. Distinguished from A. nitidum by predominance of green coloring and presence of yellow/cream variegation in A. commutatum.
