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

Growing 48-60 inches height when in bloom, and spreading those broad paddle-shaped leaves 12-18 inches wide, Canna can be the tall focal point groupings in a garden bed, or add privacy in rows or allée around the poolside seating and garden benches! The dark foliage is sure to attract all the attention with barely any work on your part!

#ProPlantTips for Care:
During the growing season, keep these full-sun plants in moderately moist to almost wet enriched soil, that is always well-drained so they do not rot. It is also a good idea to ensure that Canna has a 3-4 inch layer of arborist mulch over the surface, especially in drier, hotter areas. Provide regular fertilizer and deadhead when blooming is done. Canna rhizomes are not frost-hardy and do need to be dug in the fall before they freeze. Keep them in a cool, frost-free area in a bag in a garage or shed.
