An Exotic Native (Lobelia Cardinalis 'Black Truffle' PP25687)

Posted by John Friel on Oct 27th 2021

Isn’t that an oxymoron? Not when it’s…Lobelia cardinalis ‘Black Truffle’ PP25687

Truly red flowers are a rare commodity in the perennial market. Lobelia cardinalis is one of those rarities, with brilliant red, red blooms. And ‘Black Truffle’ brings a head-turning look to the species with rich, deep, dark foliage.

New leaves emerge glossy black, maturing to shiny maroon. The beautiful bright red blooms attract butterflies and hummingbirds, contrast dazzlingly with the luscious foliage, and make a lovely cut flower with good vase life. But despite the specific epithet, they’re of no interest to cardinals – the birds, or the church officials. Bonus: Bambi isn’t fond of them either!


Culture Corner

Lobelia cardinalis, a.k.a. “cardinal flower,” is native to much of North America. ‘Black Truffle’ was selected in Pennsylvania and trialed in Massachusetts. Standing 3’ tall, it’s hardy in USDA Zones 3 – 9.

From New England to the deep South, the species can be found where soils are consistently moist. It can stand being flooded briefly, but it’s very intolerant of drying out. Full sun won’t faze it in cool Northern climates, but the farther south you go, the more it appreciates dappled shade.


Give your customers a tasteful treat with this exotic native. ‘Black Truffle’ comes in easy-planting, fast-finishing 72-cell liners from Emerald Coast Growers – your easy choice!
