Rafinesquia neomexicana is a species of flowering plant in the family Asteraceae. Common names include desert chicory, plumeseed, or New Mexico plumeseed. It has white showy flowers, milky sap, and weak, zigzag stems, that may grow up through other shrubs for support. It is an annual plant (completes its life cycle in a single season) found in dry climate areas of the southwestern deserts of the US and northwestern deserts of Mexico.
Desert chicory is fairly disease-resistant and is generally not prone to illnesses. However, it can be vulnerable to pests and diseases present in its environment. Such infections are typically mild. Regarding care, this plant needs moderate maintenance. It should be pruned regularly to keep a neat appearance and promote healthy growth. Applying fertilizer can also encourage flowering. Desert chicory is appropriate for anyone with outdoor space, like a garden or patio, and does not demand extensive gardening experience. It may require additional attention when kept indoors.
How to keep Rafinesquia Neomexicana.
Light
Desert chicory comes from sunny, open habitats and does best in full sun. It can endure partial shade but favors direct sunlight for optimal development. This plant, which may be annual or biennial, is noted for its sun-loving habit.
Water
Desert chicory is a drought-tolerant plant that thrives in arid environments with very little moisture. It only needs to be watered once a week, making it an excellent choice for xeriscaping in desert-like climates. This plant efficiently uses the infrequent rainfall typical of these areas to support its growth cycle.
Temperature
Desert chicory can tolerate a wide range of temperatures, but its range may still be restricted by particular combinations of moisture and heat. It performs best in warm summer conditions with adequate rainfall or irrigation. Long periods of cloudy, rainy weather or sustained high temperatures increase the risk of Desert chicory dying. In winter, protecting the plant from cold can improve its chances of survival.
Fertilizer
When most of Desert chicory's blooms have opened to full size, resume fertilizing. Around the time blooms reach peak production, apply fertilizer every three to four weeks, weather permitting. Then, once Desert chicory begins producing fewer new blooms, stop fertilizing; there's no need to feed the plant when it can no longer produce more blooms.
Pruning
Desert chicory is a robust plant that showcases delicate white flowers and is highly drought-tolerant, making it ideal for arid regions. To care for it, engage in light pruning from early to late spring. This practice will remove dead stems, promote healthy growth, and improve airflow, which helps reduce pests. When pruning, aim to preserve the plant's natural shape to ensure optimal flowering and enhance its resilience in harsh conditions.

Reader questions.
How should I water my Desert chicory plant?
To water Desert chicory, you have several options for tools: a garden hose with a spray nozzle, a watering can, or any other common watering tool. This plant is not too picky about the water source - it can thrive with rainwater, tap water, or filtered water. However, it's best to avoid watering from above as it can harm the leaves and flowers and potentially cause diseases. A drip irrigation system is often the most effective method for watering Desert chicory, as it delivers water evenly and directly to the soil. If you have a container-grown Desert chicory, the watering approach is similar but you simply need to adjust the tools. Use a cup, watering can, or tap to water the soil directly.
What are the sunlight requirements for Desert Chicory?
Desert Chicory, or Rafinesquia neomexicana, requires full sun, defined as above 6 hours of sunlight daily, for optimal growth. It can tolerate partial sun, about 3-6 hours of sunlight, but thrives best in bright, open environments. When planning your garden, observe how sunlight moves through the area to choose spots that offer the right balance of light and shade for these plants.
What should I do if I give my Desert chicory too much or too little water?
Underwatering Desert chicory can be resolved by simply increasing the frequency of watering when you notice the plant lacking moisture. On the other hand, overwatering can be a more serious issue if not detected early. Overwatered Desert chicory may become susceptible to diseases, resulting in a decline and eventual death. To prevent this, it is important to choose a suitable location with ample sunlight for soil drying and good drainage to prevent water accumulation. If you have overwatered Desert chicory in a pot, it might be necessary to transfer it to a new pot with better drainage. Ensure that the new pot is equipped with sufficient drainage holes and fill it with loose soil that drains efficiently.
Can Desert Chicory grow with artificial lighting?
Yes, Desert Chicory can grow under artificial lighting when natural sunlight is insufficient, especially during winter or in less sunny spaces. For optimal growth, choose the right type of artificial light, such as LED lights, which can be customized to provide specific wavelengths of light needed by the plants. Full sun plants need 30-50W/sq ft, partial sun plants 20-30W/sq ft, and full shade plants 10-20W/sq ft of artificial light. The light source should be placed 12-36 inches above the plant to mimic natural sunlight, ensuring the plant receives 8-12 hours of light per day.
How often should I give water to my Desert chicory plant?
To keep your Desert chicory healthy, it requires regular watering during the growing season. In spring, water it once a week. As the season progresses and gets warmer, you may need to water it two to three times per week. However, be careful not to exceed this frequency as it can harm the plant. It is important to maintain relatively moist but not wet soil for your Desert chicory, regardless of how often you water. If your Desert chicory is in a pot, you will need to water it more frequently than if it were planted in the ground. Potted plants tend to dry out faster, so plan to water them a few times per week instead of just once.
What are the symptoms of inadequate light for Desert Chicory?
Desert Chicory shows several symptoms when grown indoors with inadequate light, including smaller new leaves, leggy or sparse growth, faster leaf drop, no new growth, lighter-colored new leaves, chlorosis (yellowing of leaves), sunscald (pale or necrotic spots on leaves or stems), leaf curling, wilting, and leaf scorching (brown, dry edges on leaves). These symptoms indicate the plant’s struggle with poor light conditions, affecting its photosynthesis and overall health.
How much water does my Desert chicory plant require?
To determine the amount of water to give your Desert chicory, there are a few options. One approach is to feel the soil and water until the top six inches are moist. Another method is to use a set measurement, like two gallons per week, adjusting for temperature and soil dryness. However, be cautious not to overwater if your plant needs less. For container-grown chicory, you should moisten all dry layers of soil. To check, stick your finger in the soil or water until there's a slight trickle from the drainage holes.
How can I improve light conditions for Desert Chicory?
To improve light conditions for Desert Chicory, gradually move plants to a sunnier location until they receive at least 6 hours of direct sunlight daily. For indoor plants, use a south-facing window or provide additional light with a desk or ceiling lamp for at least 8 hours daily, or consider professional grow lights. Outdoors, adapt your plants to sunnier spots gradually to avoid sunburn. Remove any obstructions that block sunlight, such as pruning trees, and for smaller plants, consider transplanting during their dormant period to a location with ample sunlight and good drainage. It's essential to manage these conditions gently to encourage healthy new growth.
How can I know if I'm giving enough water to my Desert chicory plant?
Avoiding overwatering your Desert chicory can be a bit challenging. These plants have deep roots that need weekly soil moistening, but they are also highly prone to root rot. Overwatering can lead to browning and other issues. Underwatering is less probable since Desert chicory can survive without supplemental watering for a while. However, if you wait too long to water the plant, it will likely wilt and develop dry leaves.
How do I water my Desert chicory throughout the year?
As the season progresses, the water requirements of your Desert chicory will increase. In spring, you should water once a week. However, as summer arrives and temperatures rise, you may need to water your Desert chicory more frequently, up to three times a week. This is especially important for potted Desert chicory, as the soil in containers tends to dry out faster in warm weather. In autumn, when the temperature decreases and the sun is less intense, your blooming Desert chicory may require slightly less water.
How should I water my Desert chicory as it grows?
Desert chicory goes through different growth stages throughout the year, and the amount of water it needs will vary. When starting your Desert chicory from a seed, it is recommended to provide more water than it will need later in life. During this germination period, it is important to water frequently to keep the soil consistently moist. As the Desert chicory grows above the soil after a few weeks, you can reduce the amount of water slightly compared to the seedling phase. Once the plant matures, a regular watering frequency of about once per week is suitable. During flower development, you may need to increase the amount of water slightly to support the process.
What's the difference in how you water Desert chicory inside and outside?
Most Desert chicory prefer to be grown outdoors for a few reasons. Firstly, these plants tend to grow quite tall, which may pose a challenge indoors. Additionally, Desert chicory requires more sunlight than what most indoor locations can provide. However, if you can create a suitable indoor growing environment, you might find that you need to water your Desert chicory more frequently compared to outdoor growth. This is partially due to the dryness common in indoor locations caused by HVAC units, as well as the relatively rapid drying of soil in containers compared to soil in the ground.
