Understanding Plant Options
Nature Hills offers plants in two main formats:
- Container Plants: Grown in pots with soil, sized by container volume and plant age
- Bare Root Plants: Dormant plants without soil, sized by height measurements
Container Plant Sizes

#ProPlantTips for Care:
In the shade, Elephant Ears lose its luster and some of its color. Any well-drained organic soil is best as these bulbs will rot in soggy conditions. Provide regular moisture and a well-drained organic location for best results. Elephant Ear corms can be picky about moisture because if left in dry conditions, the leaf edges will burn or brown. In warm climates, trim back the foliage as soon as it yellows in the fall or winter.
Gardeners in zones 3 to 7 can overwinter the corms indoors covered by peat moss. Dig up the corms after the leaves have been dried by frost. Store them in dry peat moss or wood shavings. Place in a warm, dark, and dry place with a temperature no higher than 50-60°F.
- Full Sun & Partial Shade
- Moist Well-Drained Soil
- Heat & Humidity Resistant Perennial Corms
- Dig Corms in Fall & Store
- Low-Maintenance Annual in Cold Climates
