Double the Beauty: Propagating the Striking Lomatium bicolor

The Lomatium bicolor, also known as the Wasatch Desert Parsley or the Two-toned Desert Parsley, is an eye-catching addition to any garden, especially those embracing a xeriscape design. This hardy perennial, native to the western United States, enchants with its umbels of tiny yellow flowers contrasted against red-tinged stems, creating a visual spectacle that buzzes with pollinators in the spring.

While procuring this unique beauty from a reputable nursery is always an option, propagating Lomatium bicolor yourself can be deeply rewarding and surprisingly simple. Here are the two most effective ways to expand your collection:

1. Seed Propagation: A Game of Patience & Timing

  • When to Sow: For best results, sow Lomatium bicolor seeds outdoors in the fall, ideally after the first frost. This cold period helps in stratifying the seeds, mimicking their natural cycle for optimal germination in the spring.
  • Sowing Depth: Plant the seeds at a depth of ΒΌ inch in well-draining soil. A mix formulated for cacti and succulents works well.
  • Location, Location, Location: Choose a spot that enjoys full sun to partial shade and boasts excellent drainage. Waterlogged soil is the nemesis of this drought-tolerant beauty.
  • Patience is Key: Germination can be erratic, with some seeds sprouting within a few weeks while others might take their time, even until the following spring. Remember, good things come to those who wait.

2. Division: Multiplying Your Floral Treasures

  • The Best Time: Late summer or early fall, when the plant’s active growth period is ending, is the ideal time for division.
  • Unearthing the Gem: Carefully dig up a mature Lomatium bicolor plant, ensuring you get as much of the root system as possible.
  • The Art of Division: Use a clean, sharp knife or garden spade to divide the plant into sections, making sure each segment has a good amount of roots and shoots attached.
  • Replanting: Place the divided sections in pre-prepared holes that are the same depth they were previously growing. Space them about 1-2 feet apart to allow for healthy expansion.
  • Post-Division Care: Water the newly divided plants well and provide consistent moisture until they get established.

A Few Extra Tips for Success:

  • Lomatium bicolor thrives in well-draining, sandy or rocky soil. Avoid overly rich soils, as they can lead to leggy growth and reduce flowering.
  • Once established, this plant is remarkably drought tolerant, requiring watering only during extended dry spells.
  • Deadhead spent flower stalks to encourage more blooms and prevent unwanted self-seeding.
  • While Lomatium bicolor is not particularly susceptible to pests or diseases, be vigilant and address any issues promptly.

Propagating your own Lomatium bicolor is a rewarding experience that allows you to connect with this unique plant on a deeper level. So, roll up your sleeves, get your hands in the soil, and enjoy the process of expanding your floral horizons with this captivating desert dweller.
