How to Grow
- Select a site with full sun and consistently moist soil.
- Amend soil with compost to improve fertility and water retention.
- Dig a hole as deep and twice as wide as the root ball.
- Place the plant in the hole with the crown at soil level.
- Backfill the hole, gently firming the soil around the roots.
- Water thoroughly after planting and mulch to conserve moisture.
Pro Tip
For a sturdier, more compact plant that won't flop, cut stems back by half in late spring before flower buds form.

Care Guide
Do

Don't
