How to Use Black Truffle Cardinal Flower in the Landscape

No matter if you have a large pond on your property, or just a spot that stays wet near the gutter downspout, Black Truffle easily creates interest.

The brilliant red flowers and lushly dark foliage adds dimension and texture to a water feature. Plant them at the edge of a stream where you'll enjoy the reflected blooms in the water.

Create a useful Rain Garden to help filter runoff from roofs and streets. People are looking to use their landscape in a way to solve ecological challenges. Add color to soil retention and shoreline reclamation projects.

These can also be grown in a perennial border with adequate supplemental water. Partner with Henry's Garnet or Scentlandia Sweetspire, and pump up the impact with a Choco Latte Hardy Hibiscus.

They can be very effective in long, narrow drifts behind lighter colored wetland plants like Evergold Sedge. Try them in front of taller Swamp Milkweed.

Use several to make a showy display. Space them 12 inches apart, measuring from the center of one to the center of the next.

You'll feel so good about your choice as you watch butterflies and hummingbirds enjoy the nectar. Tuck them into "out-of-the-way" spots, and add a comfy chair or hammock. Bring your camera and track how many flying visitors you get!

#ProPlantTips for Care

This plant requires a high amount of moisture for best performance. Add a three-inch layer of mulch over the top of the root zones in average garden soil. Give it supplemental water in times of drought.
