Planting
How to Grow
- Select a site with good drainage in sun or part shade.
- Dig a hole twice as wide as the root ball.
- Set the plant in the hole so the crown is slightly above the soil line.
- Backfill with soil, firming it gently around the roots.
- Water thoroughly to eliminate air pockets.
- Water regularly for the first season to establish, then reduce frequency.
Pro Tip
In the hottest climates, provide some afternoon shade to prevent the white portions of the leaves from scorching.
