Desert Candles: A Unique and Heat-Tolerant Plant for Dry Landscapes
Introduction
If you’re a gardener in a hot, dry region, you may want to consider adding Desert Candles to your landscape. This unique plant is native to North America and thrives in warm climates with little rainfall.
About Desert Candles
Desert Candles (Caulanthus Desert Candles) are part of the wild flora of the Mojave Desert. They are characterized by their hollow, columned stems that taper at the top and their small, purple flowers that bloom in clusters.
Although they are related to broccoli and mustard, Desert Candles are actually a succulent, meaning they have the ability to store water in their tissues. This adaptation allows them to survive in harsh, dry conditions.
Growing Desert Candles
Getting your hands on Desert Candle seeds can be a challenge, but they are available from some online sites and collectors. Once you have seeds, follow these steps to grow your own Desert Candles:
- Soak the seeds for 24 hours before planting. This will help them germinate more quickly.
- Sow the seeds in succulent soil and sprinkle fine sand over them. Do not cover the seeds completely.
- Moisten the soil and keep it lightly moist by misting.
- Cover the container with a plastic lid or clear plastic bag and keep it in a warm, bright area.
- Remove the covering once per day to let excess moisture escape. This will prevent rot and mold.
- Once the seedlings have developed several pairs of true leaves, begin to harden them off. This means gradually exposing them to outdoor conditions for increasing periods of time.
- Once the plants have acclimatized to outdoor conditions, transplant them into a well-draining bed in full sun.
- Water infrequently and let the soil dry out completely before watering again.
Where to Plant Desert Candles
Desert Candles prefer hot, dry, well-draining sites. They are hardy to USDA zone 8. If your soil is not well-draining, you can improve it by incorporating pebbles, sand, or other grit.
