The Story
Plant Bio
Buddleia, or Butterfly Bush, are fast-growing deciduous shrubs celebrated for their long, conical panicles of fragrant flowers that are irresistible to butterflies. They thrive in sun and well-drained soil. 'Blue Heaven' is a compact, mounding variety that blooms continuously without deadheading. It produces masses of fragrant, lavender-blue flower spikes from summer to frost and is non-invasive, producing little to no seed.

Planting
How to Grow
- Select a location in full sun with excellent drainage.
- Amend heavy clay soils with compost or grit to improve drainage.
- Dig a hole and plant at the same level as in the pot.
- Water thoroughly after planting.
- Water during dry spells the first year, then only in extreme drought.
- Do not over-fertilize or over-water.
Pro Tip
Prune hard in late winter or early spring. Buddleia blooms on new wood, and this encourages vigorous growth and maximum flowering.
