Buddleia ‘Black Knight’ — Butterfly Bush

Buddleia ‘Black Knight’ — Butterfly Bush

At Wrights Market, nestled in our 1938 Southern cottage, we believe every garden tells a story. Buddleia ‘Black Knight’, with its velvety, deep purple blooms and sweet honeyed scent, brings the kind of beauty that feels like home — rich, comforting, and timeless.

A Touch of History
Buddleia, often lovingly called butterfly bush, hails from Asia, Africa, and the Americas, but this particular cultivar, ‘Black Knight’, was introduced in the late 20th century in England. Its dramatic dark flowers quickly won the hearts of gardeners who love a little old-soul charm with a flair for drama. It's named for its almost black-purple blossoms, and like a true Southern gentleman, it’s both bold and gracious.

Where It Thrives
‘Black Knight’ is happiest in full sun, soaking up every golden ray like a porch-sitter on a summer morning. It prefers well-drained soil, and it’s remarkably drought-tolerant once established — perfect for the Southern climate. Hardy in zones 5–9, it’s a reliable friend across much of the country.

What It Means
Symbolizing transformation, rebirth, and joy, Buddleia is more than a pretty face. It calls to butterflies, bees, and hummingbirds — inviting life and movement into the garden. Planting a ‘Black Knight’ is like opening the front door and saying, “Y’all come in now, you’re welcome here.”

Bloom Time
This beauty blooms from mid-summer to early fall, offering long-lasting color just when the heat starts to fade the garden. The dark, spire-like flower clusters stand tall and proud — often reaching up to 8–10 feet if left unpruned.

Care Tips
‘Black Knight’ is low-maintenance and grows quickly. Give it a hard prune in early spring to encourage fuller growth and more blooms. Deadhead spent flowers to keep it blooming its heart out all season. It doesn't ask for much — just sun, space, and a little love.

Plant Companions
Surround your Buddleia with garden friends that love the sun and share its easygoing spirit:

• Coneflowers (Echinacea) – for a prairie-style palette that butterflies adore.

• Russian Sage – with its silvery foliage and violet-blue blooms for a dusty, dreamy backdrop.

• Yarrow or Coreopsis – for pops of golden yellow that sing against the dark purple.

• Ornamental grasses – like Muhly or Little Bluestem, adding soft texture and movement.

At Wrights Market, we grow more than plants — we grow connections. Bring home a ‘Black Knight’ and add a little wild magic and sweet Southern welcome to your garden.
