Vinegarweed (Trichostema lanceolatum) is an annual herb. It is also known as wild rosemary and has been used by Native American tribes as a medicinal herb for centuries. It has small, curly leaves covered with a fine, gray-white fuzz. Small purple flowers bloom in during the summer months. It is native to the west coast of the United States. You can start plants from seed or order from online nurseries. These are easy-to-grow desert plants that adapt easily to their environment.
Choose a garden bed that receives full sunlight. Vinegarweed will tolerate poor soil conditions but does require a few things for optimal growth. Loosen the soil with a hard rake. Add pine bark and pot ash to the soil and mix thoroughly to lower the pH of the soil, creating an acidic soil that vinegarweed prefers.
Scatter the seeds over the garden bed. Rake soil to cover loosely. Water until the ground is moist. Water lightly every other week until the seeds begin to sprout. Do not over-water, which can lead to root rot.
Remove plants completely once they are done blooming in the fall; otherwise, they will invade the rest of your garden and yard. Hang the plants upside down and allow to dry. Gently shake into a cloth bag or a fine net to save seeds for planting in the spring.
