HOW TO GROW

Sowing: Direct sow cardinal flower seeds in late fall, planting on the surface of the soil since these seeds need light to germinate. For spring planting, mix the seed with moist sand and store it in the refrigerator for 60 days before planting. To start indoors, sow the seed 6-8 weeks before the last frost of spring and keep the soil lightly moist until germination. Transplant the seedlings as soon as they can safely be handled and there is no chance of frost.

Growing: Keep seedings well watered and control weeds. These plants need continual moisture, and thrive even in very wet soil. They may self-sow in growing conditions. Mature plants can be divided in early spring. These flowers attract hummingbirds and butterflies, and flourish near ponds or streams. Deer, rabbit, and small pests usually avoid this plant.

Harvesting: These blooms make excellent cut flowers. Choose stalks with flowers that have just opened and place them in water immediately; strip the foliage that will fall below the surface of the water.

Seed Saving: As soon as the flowers fade, watch the seed heads carefully since the tiny seed can easily blow away in the wind. Shake the seed heads over a container to remove the ripe seed; repeat until all the seed has ripened. Store the cleaned cardinal flower seed in a cool, dry place.

Seed Germinated

I can only comment on the quality of the seed, not the mature plants. I followed the cold stratification directions and started them in peat pots. The seed germinated well, and I got tons of sprouts. While I was away on vacation, the plant sitter let them dry out, and they all died, unfortunately. I will try again next year.

This plant requires a wet location and is often found on the shorelines of lakes and swamps. It is a unreliable perennial.

DESCRIPTION

IN-STOCK ORDERS SHIP THE NEXT BUSINESS DAY VIA THE US POST OFFICE.

True to its name, this brilliant wildflower sports the scarlet hue of the cardinal. It has been called the reddest red in nature and flourishes in wet areas near ponds or streams. This flower is a native perennial wildflower that attracts hummingbirds and butterflies.
The brilliant color of this perennial Lobelia earned it its common name, which refers to the traditional red vestments of cardinals. Historical records show that explorers first encountered this native plant near a river in Canada, and sent it back to Europe for classification. The genus name of this perennial, Lobelia, honors Flemish botanist Mathias de Lobel. This flower received the Royal Horticultural Society's Award of Garden Merit.
