About Cobra Lilies (Darlingtonia californica)
Cobra lilies belong to the Darlingtonia genus, which contains just one species: californica. This small genus is part of the Sarraceniaceae, or pitcher plant family.
This family has three genera, all carnivorous plants that use sweet nectar to attract insects. The plants then drown their prey in uniquely shaped foliage filled with water and digest them using enzymes or bacteria.
Cobra lilies can grow up to two feet tall and usually grow in stands of three to 16. The plant’s tubular leaves form pitcher shapes, which bend at the top and bulge, forming a hood-like shape resembling a cobra. Another two leaves protrude from the bottom of the hood, creating a protrusion that looks like a snake’s forked tongue.
Under this tongue, a hole allows insects to enter. Once inside, sunlight permeates a translucent spot at the top of the hood. The insects are attracted to the light and buzz against the top until they tire. The inner foliage is coated with a slippery wax that helps the insects slide down to the bottom of the pitcher, and downward-pointing hairs help trap them below.
Once the bugs reach the bottom, they’re digested in a mixture of water, enzymes, and bacteria. The plants need the extra nutrients provided by the insects, as they tend to live in boggy, nutrient-poor sites.
The cobra lily is different from other pitcher plants in that it doesn’t have a hole at the top where insects and water enter. Instead, the cobra lily uses a physiological mechanism to transfer water from the roots into the pitcher.
New growth starts as a bright yellow-green but ages to maroon. In spring, the plants bloom with five-petaled purple-red flowers. The flowers hang upside down and are surrounded by green-yellow sepals.
Cobra lilies are native to southwestern Oregon and northern California. The plants grow in swampy, boggy areas and near streams in the Klamath, Salmon, Sierra Nevada, Siskiyou, and Trinity mountain ranges.
The Meaning of Cobra Lilies
It’s easy to see where cobra lilies get their common name. The plants strongly resemble a cobra with a hood spread and tongue extended, ready to strike its prey.
The cobra lily’s botanic name, Darlingtonia, nods to American botanist William Darlington. The genus name was assigned in 1853.
The species name, californica, stems from the plant’s “discovery” by 19th-century botanist W. D. Brackenridge. He found cobra lilies growing in a bog just off the Sacramento River on Shasta Peak. The species name comes from this site in California.
Brackenridge was a member of the Wilkes Expedition, an 1838 exploratory mission that included a large team of scientists, including botanists. The expedition’s goal was to explore and map the Antarctic, Pacific, and the northwestern coast of North America. Over four years, the mission explored the coastlines, cataloging many native plants.
Today, the cobra lily is the only plant with an Oregon state park completely dedicated to its preservation. Darlingtonia State Natural Site encompasses 18 acres of cobra lily habitat. Visitors can explore the fen on boardwalks and marvel at the lush stands of cobra lilies in their natural marshy habitat.
Cobra lilies make an unforgettable addition to any floral gift. The plants’ vibrant colors add a dramatic flair to a bouquet or arrangement, and the flowers are lovely in the spring. Live cobra lilies make a wonderful gift, as well. They’re perfect for plant lovers and indoor gardeners on birthdays, commemorating special occasions, or celebrating achievements.
Symbolic Values of Cobra Lilies
These intriguing plants can convey multiple symbolic meanings. Some of my favorites include:
Cobra Lilies are highly unusual and unique plants, characterized by their cobra-shaped leaves and mesmerizing patterns. They symbolize individuality and stand out as a representation of embracing one’s uniqueness and celebrating personal identity.
Cobra Lilies are known for their adaptability to challenging environments. They thrive in acidic, nutrient-poor soils and have evolved unique features to attract and capture prey. They symbolize adaptability, flexibility, and overcoming obstacles and thriving in adverse conditions.
Cobra Lilies have developed remarkable survival strategies to thrive in their native habitats. They are carnivorous plants that rely on trapping insects for nutrients. They symbolize resilience, survival, and the ability to find sustenance and grow despite challenging circumstances.
The distinctive cobra-shaped leaves of Cobra Lilies also serve the functional purpose of deterring potential threats. They resemble the shape of a striking cobra, providing a visual warning to likely herbivores. They symbolize protection, defense, and the ability to ward off threats.
Mystery and Intrigue:
Cobra Lilies possess an air of mystery and intrigue due to their unique appearance and predatory nature. They captivate the imagination and spark curiosity, symbolizing the allure of the unknown and the beauty of the natural world.
Uses and Benefits of Cobra Lilies
While not edible, the cobra lily may have medicinal uses. Research indicates that the bioactive compounds that D. californica and other members of the Sarraceniaceae family use to attract insects may also act as antioxidants and offer protection against certain microorganisms.
Scientists have long been interested in the unique way that these plants digest their prey. Cobra lilies contain chemical compounds that may have potential in the treatment of conditions such as cancers, cardiovascular concerns, diabetes, and neurodegenerative diseases.
Carnivorous plants have a history of use in traditional medicine. For instance, First Nations peoples in Canda have long used species of carnivorous plants to treat diabetes, digestive, liver, kidney, gynecological issues, smallpox, and other infectious diseases.
Cobra lilies offer benefits for pollinators, as well. Scientists have long questioned exactly how these plants are pollinated, since they don’t seem to follow many known methods. But recent studies suggest that bees and spiders may be attracted to the flowers and act as pollinators or that the plants may self-fertilize.
How to Grow Cobra Lilies
Cobra lilies require specific conditions to thrive. In their native habitat, they grow in boggy, mountainous areas near cold running streams. Replicating these conditions as closely as possible is the best way to ensure healthy, happy plants.
Outdoors, D. californica grows in USDA plant hardiness zones 7 to 10. Choose a spot with full sun to partial shade. The plants require moist soil to wet, with a neutral pH and a high nutrient content.
Water is the key element. Rainwater is always the best choice, but if it’s not available, use distilled or purified water.
The plants prefer cool water, especially around their root systems. You may need to put ice cubes around plant bases when temperatures rise about 80 degrees F.
Cobra lilies grow best when daytime temperatures are cool to warm and nighttime temperatures are cool to cold. The roots should be kept cooler than the foliage, if possible.
Ideal humidity levels will hover around 50 percent.
Caring for Cobra Lilies
Cobra lilies don’t require much pruning. If you notice dead leaves or stems, you can cut them back using clean, sharp snips.
They don’t require any fertilization. The plants receive the nutrients they need from the insects they trap and digest.
Fortunately, cobra lilies aren’t known to be susceptible to pests or diseases.
If you’re growing cobra lilies in containers, choose light-colored pots that won’t absorb heat. This will help keep the roots cool.
When growing outdoors, ensure the plants experience cold enough temperatures to trigger winter dormancy periods. The lilies may die back to the ground in freezing temperatures or keep some foliage and lie dormant. These cold periods help the plants thrive and live longer.
Best Companion Plants for Cobra Lilies
When choosing companion plants for cobra lilies, consider water and soil needs. Attractive plants that thrive in boggy conditions include:
- Ligularia, a water-loving and shade-tolerant plant that prefers cooler temperatures and blooms with yellow flowers
- Purple loosestrife (Lythrum salicaria) for long-lasting flowers that attract pollinators
- Small reed mace (Typha minima), an ornamental grass that loves boggy spots
- Rodgersia, an easy-to-grow perennial that thrives in moist soil and blooms with white and pink flowers
- Meadowsweet (Filipendula ulmaria), a perennial that prefers boggy soil and blooms with white, aromatic flowers
Creative Uses for Cobra Lilies
Cobra lilies make a unique and eye-catching addition to a bog garden. They grow in clumps of dramatically colored foliage and are a perfect statement in a wet spot in the landscape or near a pond or stream.
When growing indoors, consider using a glass dome or terrarium to highlight these unusual plants and keep humidity levels at appropriate levels.
