Planting
How to Grow
- Choose a location that receives at least 6 hours of direct sun
- Ensure the soil is very well-drained; amend if necessary
- Dig a hole as deep and twice as wide as the pot
- Place the plant in the hole, with the crown level with the soil
- Backfill the hole and water in well to remove air pockets
- Avoid heavy mulching, especially around the crown
Pro Tip
Plant in average to poor soil. Rich soil can lead to lush foliage growth with fewer flowers.

Care Guide
Do
- Provide full sun for maximum flowering.
- Allow soil to dry out between waterings.
- Prune back hard in early spring to promote vigorous growth and flowering.
Don't
- Do not plant in wet, poorly drained soil.
- Avoid fertilizing, as it can reduce flower production.
- Do not prune in the fall, as this can encourage tender new growth that gets damaged by winter cold.
