Propagation of Calochortus caeruleus var. fimbriatus
Calochortus caeruleus var. fimbriatus, commonly known as the fringed blue-flowered mariposa lily, can be propagated through several methods, including seeds, bulbs, and offsets.
Propagation by Seeds
The most common method of propagating Calochortus caeruleus var. fimbriatus is through seeds. Collect the seeds during the summer when the capsules split open, revealing the seeds. Store the seeds in a cool, dry place until you are ready to plant them in the fall.
Sow the seeds in a well-draining soil mix. Cover the seeds lightly with soil and water them gently. Place the pot in a cool, shaded area and keep the soil moist. The seeds should germinate in 4 to 6 weeks. Once the seedlings have grown to a few inches tall, transplant them into separate containers or into the garden.
Propagation by Bulbs
Calochortus caeruleus var. fimbriatus can also be propagated through bulbs. Wait until the leaves have turned yellow and withered away before digging up the bulbs. Gently remove the soil and separate the bulbs. Replant the bulbs in a well-draining soil mix, making sure that the bulbs are covered with soil but the neck is exposed.
Water the bulbs well and place them in a cool, shaded area. Keep the soil moist until the bulbs establish new roots for a few weeks. Once the bulbs have developed new roots, you can transplant them into separate containers or into the garden.
Propagation by Offsets
Calochortus caeruleus var. fimbriatus can also be propagated through offsets. When the plant has finished flowering, gently dig around the base of the plant to locate the offsets. Carefully separate the offsets from the main plant and plant them in a well-draining soil mix.
Water the newly planted offsets well and place them in a cool, shaded area. Keep the soil moist until the plant develops new roots for a few weeks. Once the offsets have established new roots, you can transplant them into separate containers or into the garden.
It's important to note that Calochortus caeruleus var. fimbriatus grows best in well-draining soils and prefers a cool, shaded environment. Propagation is best done during the fall to ensure that the plant has time to establish itself before the warmer months arrive.
