The Story

Plant Bio

Buddleia, or butterfly bush, is a fast-growing shrub prized for its long panicles of fragrant flowers that are highly attractive to pollinators throughout the summer. CranRazz is noted for its large, full flower trusses and vibrant, saturated cranberry-red color. It offers a richer, deeper red tone than many other butterfly bushes on a sturdy, upright plant.

Uses & Benefits:

CranRazz offers a rare and sought-after color in the summer garden with its deep cranberry-red blooms. The large flower spikes create a dramatic, season-long display, adding height and texture to mixed borders. Its silvery-green foliage provides a nice contrast to the vibrant flowers.

This is a workhorse shrub for sunny, dry locations. Its resistance to deer, rabbits, and drought makes it a problem-solver in many gardens. It grows quickly to fill a space and provides an abundance of flowers for indoor arrangements.

Buddleia are famously known as 'butterfly magnets' for a reason. They provide a crucial, high-energy nectar source for countless species of butterflies, as well as bees, moths, and hummingbirds, making them a cornerstone of any pollinator-friendly garden design.

Planting

How to Grow

Find a location with at least 6 hours of direct sunlight daily.
Ensure the soil is well-drained; Buddleia despises wet roots.
Dig a hole twice the width of the plant's container.
Set the plant in the hole so its crown is level with the soil surface.
Backfill, firm the soil gently, and water in well.
Water regularly during the first growing season to establish.

Pro Tip

Plant in average or even poor soil; overly rich soil can lead to weak, floppy growth and fewer flowers.

Do
