How to Grow Fritillaria — Fritillary

Fritillary

Fritillaria–commonly called fritillary–is a bulbous perennial with pendulous bell-shaped, tubular, or saucer-shaped flowers solitary or in umbels. Leaves are lance-shaped and rise from basal bulblets and then continue in whorls with leaf-like bracts above the flowers.

Fritillaria is a large genus of about 100 species in the lily family. The genus includes larger plants well suited for beds and borders as well as small species suited for rock gardens. All species grow from bulbs.

Blooms are solitary or borne erect in unbranched clusters. Each flower consists of six petal-like tepals. Many species have a checkered pattern or a pattern of contrasting colors.

Fritillaria are best grown in full sun or light shade with humus-rich, moist but well-drained soil. Some species can be difficult to grow; they require almost perfect drainage to thrive.

Plant fritillaries at least 4 times the height of the bulb. The soil should be deeply prepared so that the bulbs sit in well-drained soil.

When to Plant Fritillaria

  • Plant bulbs as soon as available in fall usually late summer or early fall so they don’t dry out.

Planting and Spacing Fritillaria

  • Space Fritillaria bulbs 6 inches to 2 feet apart depending on the variety.
  • Plant Fritillaria in groups of two or three.
  • Crown imperial Fritillaria is spaced 8 to 12 inches deep; plant checkered lily 3 to 4 inches deep.
  • Plant bulbs 4 to 6 inches deep.
  • Set bulbs in the ground at a 45-degree angle to prevent tops from collecting water.

How to Water and Feed Fritillaria

  • Fritillaria needs abundant water during the growing season. Fritillary needs less water once dormant in summer.
  • Fertilize Fritillaria with a bulb fertilizer in spring.

Fritillary Care

  • After blooming, do not cut off browning foliage; it’s needed to rejuvenate the plant.
  • Remove brown foliage when the foliage pulls off without resistance.

Fritillary Common Problems

  • Rust and leaf spot can occur.
