Soil Requirements
Plagiobothrys tener prefers well-drained soils with a slightly acidic to neutral pH range between 5.0 and 7.5, but it can tolerate a wide range of soil types. It can grow in sandy, loamy or clay soils that are not too wet or dry.
Cultivation
Plagiobothrys tener (Greene) I.M. Johnston var. tener is a native wildflower found in sandy soils, grasslands, and prairies. It is a low-maintenance plant that is easy to grow in a garden setting. The plant prefers well-drained soil in full sunlight to partial shade. It is a low-growing annual or perennial, and the flowers bloom in the spring and summer.
Watering Needs

During the summer months, the plant may require additional watering as the soil tends to dry out faster.
Fertilization
Plagiobothrys tener does not require a lot of fertilizer. Adding a slow-release fertilizer during planting is sufficient to give the plant the necessary nutrients it needs to mature. An organic, all-purpose fertilizer can also be added once a month during the growing season. The excess use of nitrogen-rich fertilizers should be avoided as it can lead to excessive foliage growth instead of flower production.
Pruning
Plagiobothrys tener does not require significant pruning. The plant typically grows low to the ground and maintains its shape without much assistance. However, deadheading can be done to encourage the plant to produce more flowers. When the flowers begin to fade, cut the stem below the dead flower to promote new growth and more blooms. Pruning should be done in the fall or winter when the plant is dormant.

Plagiobothrys tener (Greene) I.M. Johnston var. tener, commonly known as rough popcorn flower or alkali popcorn flower, belongs to the family Boraginaceae. This annual plant is native to North America and can grow up to 1.5 feet tall. Propagation is the process of producing new plants from existing ones. Plagiobothrys tener can be propagated through various methods which are discussed below.
Seed Propagation
Plagiobothrys tener can be propagated from seeds. The seeds of this plant are small, black, and shiny. Seed propagation can be done indoors or outdoors depending on the climate and season.

It involves digging up the plant, cutting the root ball into several sections, and replanting them in separate areas. Make sure that each section has roots and foliage. Transplanting should be done during the early spring when the soil is moist.
Cuttings
Propagation through stem cuttings is also possible but it is not commonly practiced with Plagiobothrys tener. Also, it has low success rate. Cuttings should be taken from new growth and should be dipped in rooting hormone before planting them in a moist potting mix. Cover the pot with a clear plastic bag and place it in indirect light. Check the cuttings for any signs of growth, which may take two to three weeks.
Propagation can be an enjoyable and rewarding experience, but it requires patience and proper knowledge of the plant.
