Lupinus Subcarnosus
Known as the "Sandyland Bluebonnet," this charming wildflower holds a prestigious place in history as the original state flower of Texas. While it is often overshadowed by its flashier cousin, the Texas Bluebonnet (Lupinus texensis), this species is beloved for its delicate, deep-blue blossoms that paint the sandy prairies in shades of indigo every spring. It is a hardy pioneer plant that thrives where others struggle, signaling the official end of winter.
In 1901, a heated "Flower War" broke out in the Texas Legislature. Some wanted the cotton boll to be the state flower, while others wanted the cactus. Lupinus subcarnosus won the title initially, but many felt it was too "dainty." After 70 years of debate, the law was finally changed to include every variety of Bluebonnet as the collective state flower!
To grow Lupinus Subcarnosus (Texas Bluebonnet) plants, follow these steps:


For optimal growth and health, fertilize the plant in the early spring with a balanced fertilizer, such as a 10-10-10 or 12-12-12 blend. Apply the fertilizer according to the package instructions, typically broadcasting it evenly over the soil around the plant and then watering thoroughly. During the growing season, you can also side-dress the plant with additional fertilizer about 6-8 weeks after planting or when you see new growth emerging. Be sure to avoid getting fertilizer on the leaves or stems of the plant, as this can cause burn or damage.
Lupinus Subcarnosus grows best in a well-draining soil that is not too heavy or compacted. It prefers a soil that is slightly acidic with a pH of around 6.5 to 7.5. The soil should also be nutrient-rich, but not overly fertile, as excess fertilizer can lead to leggy growth and reduced flowering. To ensure the soil is suitable for this plant, it's recommended to perform a soil test beforehand. The plant prefers to grow in full sun but can tolerate some shade. It's important to ensure the plant is not overwatered, as it prefers dry to moderate soil moisture levels. Adding organic matter to the soil can also improve its overall health and allow the plant to thrive.
To propagate this plant, collect mature seeds from the plant during the fall season. Place the seeds in a paper bag and store in a cool, dry place until the following spring. In the spring, sow the seeds in a well-draining soil mixture and cover lightly with soil. Water regularly and provide bright, indirect light. The seedlings should emerge within a few weeks and can be transplanted into individual containers once they have developed several true leaves. Alternatively, the plant can be propagated through stem cuttings taken in the spring or early summer. Select a healthy stem and cut a section with a length of approximately 4-6 inches. Remove any lower leaves and plant the cutting into a potting mixture or directly into the ground. Keep the soil moist and provide bright, indirect light. The cutting should begin to root within several weeks and can be transplanted into individual containers or outside once it has established roots.
