The Story
Plant Bio
Buddleia, or butterfly bush, is a fast-growing deciduous shrub prized for its long, conical flower trusses that are highly attractive to butterflies and other pollinators. They bloom on new wood. 'Miss Ruby' is a standout hybrid known for its compact, manageable size and intensely saturated, rich magenta-pink flowers that bloom continuously from summer to frost. It is a sterile or near-sterile cultivar, so it will not become invasive.

Planting
How to Grow
- Select a location that receives at least 6-8 hours of direct sun.
- Ensure the soil has excellent drainage; amend with gravel if necessary.
- Dig a hole the same depth and twice the width of the container.
- Place the plant in the hole, ensuring the crown is at soil level.
- Backfill with native soil and water it in.
- Avoid mulching heavily, as they prefer soil on the drier side.
Pro Tip
Do not amend the soil or fertilize; butterfly bushes thrive and flower best in average to lean, well-drained soil.

Care Guide
Do
- Provide full, all-day sun for the best performance.
- Cut the entire plant back hard in early spring.
- Deadhead spent flowers to promote a longer bloom season.
- Plant in very well-drained, even gravelly, soil.
Don't
- Don't plant in shade; it will be leggy with few flowers.
- Avoid wet, heavy clay, or constantly damp soil, which causes root rot.
- Don't fertilize; rich soil leads to weak growth and fewer blooms.
- Don't prune in the fall; wait until spring.
