Get ready to do a doubletake this spring! Gorgeous tropical-looking red blooms, the showy Rubra Fritillaria (Fritillaria Imperialis 'Rubra') takes late spring ephemerals to a new level with their fantastic blooms that look like they belong on an exotic beach! These fragrant blooms look like nothing else you've seen in the typical spring garden!

Its quirky and flamboyant appearance makes it a crown jewel for gardeners! Featuring drooping clusters of deep red bells with pointed petals that ring the top of a tall, sturdy green stem. Like a green crown, each flower cluster is topped with a spikey ball of leaves rising over the blooms! The bulbs of Red Crown are dramatic focal points and thrillers in the landscape and in floral bouquets, you’ll feel like you joined a luau!

Growing upward of 3 feet in height, the fast-growing stems rise above the green foliage clumps with a curious ring of green leaves skirting midway along the stems! Rubra Fritillaria, also known as Crown Imperials, are easy to grow in USDA growing zones 5 to 8, and usually not bothered by deer, rodents, or Black Walnut juglone. These bulbs naturalize and form little colonies throughout the landscape.

Planting and Application:

This plant doesn't just demand a closer inspection - it requires one! Rubra Fritillaria are must-haves for poolside and Rock Garden displays, as curiosities at the back of the garden border, or adding a tropical element to modern, architectural plantings. Best in rows and groupings, these Spring bulbs have a whimsical look! It's also happy to shine as a background plant that reaches its impressive crown high above other plants. It's happy to shine with a tropical flair no matter where you plant it!

When you look like this, you have no choice but to stand out, which is why this Red Crown Imperial makes a superior accent plant. Vertical elements, Rubra Imperials are dramatic thrillers in pots and planters around sunny porches, as unique architectural accents on front porches, or as unique features in mixed seating area planters that pollinators and children will be drawn to!

#ProPlantTips for Care:

Fritillaria are easy-to-care-for perennial bulb plants! They must have well-drained soil and lots of sunshine all growing season but can handle partial sun in hotter growing zones. In colder zones, plant deeper and mulch well so they can survive the winter. Add bulb fertilizer to each hole for best results and provide moderate moisture during the growing season. Deer and rodent resistant, there are no pests or disease issues to worry about. In fact, their only issue is with soggy soil that will rot the bulbs. Deadhead once the flowers fade but keep the leaves to make food for the bulbs, then prune them back when the foliage yellows.

  • Full Sun or Partial Shade
  • Moderately Moist Well-Drained Soil
  • Deadhead After Bloom, Prune to Ground When Leaves Yellow
  • Very Cold & Heat Hardy
  • Deer & Rodent Resistant
