Cardinal Flower is a herbaceous perennial that grows in clumps usually 2'-4' tall and a foot or less in diameter. The stems and leaves have a purplish tint and no wildflower is brighter red. Cardinal Flower spends the winter as a basal rosette of 5-7" elliptic leaves flat on the ground, then in springtime it sends up one or more unbranched stems with smaller leaves that by mid-summer, June to September, develops a terminal raceme of brilliant scarlet-red flowers, each about 1-2" long.
Cardinal Flower is native to both North and South America, and was first introduced in England around the early 1600s. It was named for the Roman Catholic miters that are red in color, considered both regal and a higher standard. In today's gardens, it is a butterfly and hummingbird magnet, plus makes a great focal point in many landscapes. This plant is propagated via dividing the fibrous root system and should be divided every three to four years for a continuous stream of blooms.

Mail Order: What To Expect
Plants you receive by mail need time to adjust. Cardinal Flower will arrive in a 2" Pot (roots with some foliage). Upon arrival, they may not appear lush but given time & proper care, they will flourish!
Plant directly into pond and water garden planting shelves or you fill individual planting containers loosely with aquatic planting media, placing the appropriate fertilizer tablets into the bottom half of the planting media and covering them over, then filling planting media 2/3 to the top. Place the plant in the center of the pot with the roots spread out over the planting media, and then continuing to cover the roots with planting media. The crown of the plant, which is the connection between the roots and stems, can usually be about 1" below the surface of the planting media for best results. Avoid using bagged potting mix and other lightweight soils because they will float and continually cloud pond water.
Regular fertilization of your Cardinal Flower will keep it growing well all season long. CrystalClear® Thrive™ Aquatic Plant Fertilizer or TetraPond® LilyGro™ Aquatic Plant Food or Laguna Plant Grow Fertilizer Spikes can be pushed into the soil at planting time and from April through August, following all manufacturers' recommendation for fertilizer application rates.
For best results, trim or prune as leaves and flowers begin to turn yellow or brown, remove them completely, discarding them to keep as much excess organic material out of water-body as possible.
All leaves and stems will begin to die off as winter arrives. If planted directly into a bog area, plants should be left alone after trimming any dead foliage to 1 to 2" above the top of the water. Plants that are on plant-shelves, in planting containers, should be trimmed to 1 to 2" and then gently lowered into the ponds deeper water. All plants submerged before winter must be brought back up as soon as the ice has permanently thawed, and before any plant growth occurs. In Zones 6 and warmer, most pond plants can tolerate being left in place without moving them at all.
