Overview of Caulanthus inflatus S. Wats.
Caulanthus inflatus S. Wats. is a plant species in the family Brassicaceae. It is commonly known as desert candle, desert candlestick, desert mustard, and inflated wild cabbage. It is native to the United States, specifically in the southwestern states such as California, Arizona, Nevada, and Utah. It is usually found in desert washes and rocky slopes within the elevation range of 100 to 1900 meters.
Physical Description
The desert candle can grow up to 7 feet tall, with the main stem being covered with sparsely distributed leaves. The leaves are wavy, shiny, and narrow, with a length of around 5 inches. The plant produces attractive yellow flowers on long stems that can grow up to 1 foot long. The flowers are four-petalled and bloom between March to April.
What sets the desert candle apart from other plants is the inflated structure of its fruit, which is why it has the name "inflatus" in its scientific name. The inflated fruit is around 1 inch long and has a cylindrical shape that turns light brown as it dries. The fruit contains a lot of seeds that are released when the seedpods break open.
Uses
The desert candle plant has been used for food, medicine, and ornamental purposes. Native Americans traditionally consumed the young leaves, cooked roots, and seeds of the desert candle as a source of nutrients. The plant has also been used to treat a wide range of illnesses, including colds, coughs, and arthritis.
Due to its striking yellow flowers and unique appearance, the desert candle plant is also popular as an ornamental plant in gardens and landscapes.
Despite its usefulness in some aspects, it is essential to note that the desert candle plant can be harmful to livestock when ingested and can cause digestive problems. It is not recommended to plant this species near livestock grazing sites.
Light Requirements
Caulanthus inflatus S. Wats. typically requires full sun to thrive. It is a plant that evolved in the arid regions of the southwestern United States, which means it can tolerate extreme light conditions. As such, it is not a suitable plant for shady spots.
Temperature Requirements
Caulanthus inflatus S. Wats. is adapted to hot and dry conditions. It grows well in regions where the temperature ranges from 75 to 95 °F during the day and 50 to 65 °F at night. It is a hardy plant that can withstand mild frost, but it does not grow well in regions with consistently low temperatures.
Soil Requirements
Caulanthus inflatus S. Wats. prefers well-drained soils. It does not grow well in heavy clay soils with poor drainage. If planting in heavy soils, it is important to amend the soil with sand and organic matter to improve drainage. This plant can grow in soil with various levels of fertility but generally prefers mildly acidic soils (pH 6.0-7.0).
Additionally, it is essential to ensure soil moisture is not excessive to avoid root rot. This plant is drought-resistant and thrives in moderately dry conditions. Overwatering or waterlogging can lead to root rot or other fungal diseases.
Cultivation of Caulanthus inflatus S. Wats.
Caulanthus inflatus S. Wats. is a native California plant that is often found on rocky slopes, sandy flats, and among chaparral. With careful attention and a bit of know-how, you can reward your green thumb by cultivating these beautiful flowering plants in your own garden.
To begin with, it is recommended to plant these flowers in the spring or fall, as they thrive in cool weather. The plant prefers full sun and dry, well-draining soil. Make sure to choose a location with plenty of drainage and good air movement to avoid fungal diseases.
Caulanthus inflatus S. Wats. is a hardy plant that is easy to care for and relatively pest-free. Weeds that sprout up around the plant should be kept under control so that the plant can channel all its energy to its growth and blossom.
Watering Needs of Caulanthus inflatus S. Wats.
Since Caulanthus inflatus S. Wats. is native to drought-stricken regions of California, it naturally doesn't require a lot of water. It's suggested that rather than watering frequently, allow the soil to dry slightly before the next watering. Established plants generally do well with medium to moderate watering once or twice a week during the growing season. When winter arrives, it's best to ease up on the watering, as the plant is dormant during this time.
Overwatering can lead to root rot, so it's important to keep track of the moisture levels in the soil. During periods of high humidity or rainy weather, avoid watering and wait for the soil to dry naturally before the next watering. Care should be taken not to wet the foliage, which could lead to fungal diseases.
Fertilizing Caulanthus inflatus S. Wats.
Caulanthus inflatus S. Wats. doesn't require much fertilization. However, if your soil is poor, you may want to add a slow-release or liquid fertilizer that is low in nitrogen. A fertilizer that is too high in nitrogen can cause excessive growth of foliage at the expense of flowers.
Avoid applying fertilizer during the winter months, when the plant is dormant. Generally, one or two applications of fertilizer per growing season should be sufficient to nourish the plant. As always, it is crucial to follow the label directions of any fertilizer you choose to use.
Pruning of Caulanthus inflatus S. Wats.
Caulanthus inflatus S. Wats. requires little in the way of pruning. In fact, excessive pruning can harm the plant and reduce its flowering potential. If you must prune your plant, do so sparingly.
Deadheading spent flowers, or removing them as soon as they fade, allows the plant to channel energy into producing new growth and blossoms instead of producing seeds. You can also remove any diseased or damaged parts of the plant as needed.
Additionally, in late winter or early spring, you can prune back some of the previous year's growth to encourage bushier growth and a more abundance in blooms. Remember, however, that over-pruning can lead to stress on the plant and a decreased number of flowers.
Propagation of Caulanthus inflatus S. Wats.
Caulanthus inflatus S. Wats. or desert candle is a hardy plant that is easy to propagate from seeds. There are two primary methods of propagation – direct sowing and transplanting seedlings.
Direct Sowing
Direct sowing is the easiest and most common method of propagating Caulanthus inflatus S. Wats. The seeds should be sown directly in the garden bed in early spring after the last frost, or in the fall before the first frost. The seeds are small and should be sown thinly, about an inch apart to avoid overcrowding. The garden bed should be well-drained and have fertile soil with a pH between 6.8 and 7.2.
Once sown, the seeds should be covered with a thin layer of soil and kept moist until germination. Germination usually takes about 7 to 10 days, and seedlings will emerge within 14 to 21 days. When the seedlings have two or three sets of true leaves, they should be thinned to a spacing of about 12 inches.
Transplanting Seedlings
Transplanting Caulanthus inflatus S. Wats. seedlings is another way to propagate the plant. This method is ideal for gardeners who want to get a head start on the planting season or for those who do not have a suitable space for direct sowing.
The seeds should be sown indoors in early spring, about six to eight weeks before the last frost. The seedlings should be kept in a warm, sunny location and watered regularly. When the seedlings have two or three sets of true leaves, they can be transplanted to their final location in the garden.
The hole for the transplant should be about twice the size of the root ball and filled with well-drained soil and compost. The soil should be lightly pressed around the base of the plant to remove any air pockets. The plant should be watered immediately after transplanting and kept moist until it becomes established.
Overall, Caulanthus inflatus S. Wats. is an easy plant to propagate, making it an excellent addition to a garden. Whether you choose direct sowing or transplanting seedlings, this plant is sure to thrive with proper care and attention.
