The flame lily (scientific name: Kniphofia uvaria) is a perennial flowering plant native to South Africa. It’s a member of the Asphodelaceae family and gets its common name from the red-hot poker-shaped flower heads.

These plants produce dense clusters of tubular flowers in shades of red, orange and yellow atop tall, thick green stems. The flowers bloom from late spring through summer, providing a sizzling burst of color in gardens.

Flame lily plants can grow up to 4-5 feet tall when mature, with strap-like semi-evergreen leaves forming a dense clump at the base. Their exotic look and ability to attract hummingbirds and butterflies make them a popular choice for landscaping.

Growing Conditions for Flame Lilies

Like most plants, flame lilies thrive when their specific growing needs are met. Here are the ideal conditions:

Sun Exposure

These sun-lovers need at least 6 hours of direct sunlight per day. Full sun is best, but they can tolerate partial shade – especially in hot climates.


Flame lilies prefer well-draining soil that’s moderately fertile and slightly acidic (pH 6.0-7.0). Sandy or rocky soils are ideal as they prevent waterlogging.


During the growing season, keep the soil evenly moist but not saturated. Allow the top inch or two to dry out between waterings. Reduce watering in winter.


Originating from warm South African climes, flame lilies can’t tolerate freezing temperatures. In cold regions (Zones 5-6), they’re treated as annuals or the rootstock is dug up and overwintered indoors.

Where to Plant Flame Lilies

Flame lilies make a bold statement in sunny borders, rock gardens, raised beds or containers. Their vertical shape works well for creating eye-catching focal points or backdrops in landscaping.

Plant them in groups of 3-5 for maximum impact. Space each plant 12-18 inches apart, further for larger varieties. Flame lilies also attract pollinators when planted near vegetable gardens.

If growing in containers, use a large, well-draining pot (at least 12 inches wide and deep) with a quality potting mix.

How to Plant Flame Lilies

Plant flame lily bulbs or divisions in early spring, after the last frost has passed. Here are the steps:

  1. Prepare the planting area by digging an 8-10 inch deep hole and amending the soil with compost or manure.
  2. Set the bulbs or rhizome divisions 6-8 inches deep and 12-18 inches apart, with the growing points facing up.
  3. Cover with soil and water thoroughly after planting.
  4. Apply a 2-3 inch layer of mulch (bark chips, pine straw) to retain moisture and discourage weeds.
  5. Water regularly during the first season to establish deep roots.

Ongoing Care for Flame Lilies

With their tropical origins, flame lilies require attentive care – especially during hot summers. Follow these tips:


Keep the soil consistently moist during active growth, providing about 1 inch of water weekly (more in extreme heat). Reduce watering in fall as plants go dormant.


Feed flame lilies in early spring using an balanced fertilizer or compost to promote lush foliage and more flowers.


Remove spent flower stalks down to the base to encourage more blooms and neaten the plant’s appearance.

Winter Care

In cold climates, cut back stems to the ground after frost and cover the area with 4-6 inches of mulch. Lift and overwinter tender bulbs indoors if extreme freezing is expected.

Dividing Flame Lilies

These vigorous plants may need dividing every 3-4 years as clumps get overcrowded. Carefully dig up the rootstock and separate the rhizomes in early spring.

Common Problems and Solutions

Though generally low-maintenance, flame lilies can sometimes experience a few issues. Here’s how to troubleshoot:

  • Yellowing Leaves: Usually a sign of overwatering or poorly draining soil. Allow the soil to dry out and improve drainage.
  • No Flowering: Insufficient sunlight is the main culprit. Relocate plants to a sunnier spot or prune surrounding plants for more light.
  • Leaf Spots: Watch for fungal diseases like red leaf spot which cause reddish-brown spots or blotches. Remove affected foliage and treat with an appropriate fungicide.
  • Aphids or Mealybugs: Check undersides of leaves for these common sap-sucking pests. Dislodge with a strong spray of water or use insecticidal soap.

Varieties of Flame Lilies
