We grow just a select few Dahlias now but over the decades we’ve been able to observe hardiness by cultivar. This is consistently one of the hardiest. And its a wonderful perennial. Finely divided foliage is dark, nearly black on a compact plant to 2′ x 2′ with stunning black/velvet red single flowers. These appear consistently from June to frost. Shorter stems lead to a smaller cut flower but it is still wonderful none-the-less. The intense deep flower color is a perfect match for the foliage yielding a dark tinted plant. Provide contrasting light to golden colored foliage for extra depth. Excellent border perennial for full sun and rich, well drained soil with regular summer irrigation. This hardy perennial requires very little protection other than a layer of mulch in autumn. Even a layer of leaves will provide a modicum of cover. Emerges with truly warm weather in spring. Protect emerging plants from snails/slugs. Full grown plants seem less affected. Loved by pollinators and moderately deer resistant. Far from 100% but still one of the last they will munch.
