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.

Uses & Benefits:

Its compact size allows it to be used in small gardens, containers, or the front of the border, providing a non-stop show of fragrant blue flowers all summer long.

This cultivar is sterile or produces very little viable seed, addressing the invasive concerns of older Buddleia davidii varieties. Its drought tolerance makes it a water-wise choice.

The nectar-rich flowers are exceptionally attractive to a wide array of butterflies, bees, and other pollinators, making it a cornerstone of a pollinator-friendly garden.

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.
