Dianthus 'Firewitch'

Dianthus 'Firewitch': Hot Magenta Over a Blue-Grey Carpet

'Firewitch' casts exactly one spell: hot magenta flowers that smell like somebody's been baking with cloves. The blue-grey mat stays put all winter, the deer keep their distance and the butterflies line up. NO BROOMSTICK. JUST RESULTS.

Where to Plant: Use it to edge a path, carpet a rock garden, fill cracks in a stone wall or spill over a raised bed. Plant it close to where people walk so they catch the scent. The evergreen mat adds a bit of colour in winter when the snow melts back.

Companion Plants: Edge a sunny, dry bed with 'Firewitch' and back it with pink and white for a long run of colour. Salvia 'Pink Profusion' adds dark pink spikes at 36 to 41 cm from June to August. Echinacea PowWow® White brings white coneflowers at 40 to 60 cm from June to September. Achillea New Vintage™ Rose adds rose-pink heads at 66 to 71 cm from June to August. Pennisetum alopecuroides arches behind at 75 to 100 cm with soft bottlebrush plumes.

Plant Care: Plant in full sun, in average, well-drained soil. Neutral to alkaline soil suits it. It cannot stand soggy soil, especially in winter, so add grit to heavy clay or use a raised bed or slope. Water through the first season. After that, it rarely needs help. Shear off the faded flowers after bloom to keep the mat tidy and coax a few more flowers. Leave the foliage over winter and trim any damaged bits in spring. Divide or take cuttings every few years if the mat opens in the centre.

History: 'Firewitch' was introduced in Germany in 1957 as 'Feuerhexe', stayed fairly unknown in North America until the late 1980s, and was named Perennial Plant of the Year in 2006 by the Perennial Plant Association. The species, cheddar pink, is native to Europe and takes its name from Cheddar Gorge in England, where it grows wild.

Final Thoughts: Tuck it along a sunny path edge and brush past it on purpose. YOUR NOSE WILL THANK YOU AND THE DEER WILL SULK.
