Planting and Maintenance Cardinal Flower
The Red Cardinal Flowers are super easy to plant and maintain, so they can be used by any gardener regardless of their experience. They prefer to grow in sluggish, fertile soil and are best grown in shade rather than sun. Sow by loosening the soil, placing the roots, covering them with soil, and watering deeply. They are low-maintenance and require moisture for growth and regular deadheading to maintain long blooming.
Colors of The Red Cardinal Flowers
These perennials usually flower during mid-to-late summer, and their ruby-red blooms last for weeks. The plant is dark green with dark green leaves, and its spikes stand out. Once the flowers open, they shrivel up and emerge in pods as a second season of interest. The foliage remains green throughout the season, so the plant does not look overgrown.

The plants are perennials growing upright, and their flower heads reach heights of 2 to 4 feet. Their graceful and tall stature makes them ideal for adding texture to garden beds or naturalized areas. Given time, Cardinal Flowers will bloom year after year to bring enduring beauty to your garden.

Care
Cardinal Flower (Lobelia cardinalis) thrives in moist, well-drained soil with consistent moisture. Keep the soil consistently wet and mulched to retain moisture. Fertilize lightly in early spring. Remove spent flowers to promote more flowers and prevent self-seeding.
Plant Reproduction
Cardinal flowers are spread by self-seeding, sending out offshoots, and bending stems.
Planting bare-root perennials is best in any season if they are dormant; we only sell dormant plants. Planting them year-round is also excellent if you can get dormant perennials. When your bare-root perennials arrive, soak the roots in water for a few hours to rehydrate them. Lant by digging a hole wide enough to spread the roots comfortably and deep enough to place the top portion crown (where the roots meet the stem) at or slightly above ground level. Position the plant in the hole, backfill with native soil, and gently firm the soil around the roots—water well after planting to settle the soil around the plant and eliminate air. Apply a 2-3 inch layer of mulch to keep weeds at bay and moisture locked in, keeping the mulch away from the crown. Irrigate plants regularly during the first few weeks of drought; never water in full sun, and water late in the evenings to ensure the roots are established well. Fertilize sparingly in the first year, using a balanced, slow-release fertilizer in subsequent years as needed.
