If you plan to grow Samolus ebracteatus Kunth ssp. alyssoides (Heller) R. Knuth, it is recommended to start the plant from seeds as the plant does not transplant well. To ensure successful germination, sow the seeds in a container filled with moist soil in early spring or late fall. Keep the soil moist, but not waterlogged, and germination typically occurs within two to three weeks.
Watering Needs
Samolus ebracteatus Kunth ssp. alyssoides (Heller) R. Knuth prefers moist to wet soils, and it is important to keep the soil consistently moist. During dry spells, provide the plant with extra water to ensure it receives enough moisture. However, be careful not to overwater the plant, as this can lead to root rot.
Fertilization
Samolus ebracteatus Kunth ssp. alyssoides (Heller) R. Knuth does not require fertilizer to thrive.

Be careful not to over-fertilize, as this can cause the plant to produce too much foliage and fewer blossoms.
Pruning
Samolus ebracteatus Kunth ssp. alyssoides (Heller) R. Knuth does not require much pruning. If the plant becomes too bushy, you can trim back the tips of the stems in early spring. This will promote new growth and a fuller plant. Additionally, deadheading spent flowers will encourage the plant to produce more blossoms.
Propagation of Samolus ebracteatus Kunth ssp. alyssoides (Heller) R. Knuth
There are several methods for propagating Samolus ebracteatus Kunth ssp. alyssoides (Heller) R. Knuth, including seed propagation, division, and stem cutting.
Seed Propagation
Propagation through seed is the most common method, and should be done during the spring or summer when the plant is actively growing. The seeds should be sown in trays or pots filled with a well-draining potting mix. The trays or pots should be kept moist but not waterlogged, and should be placed in a bright but shaded area.
After a few weeks, the seeds will germinate and begin to grow. Once the plants have developed a few true leaves, they can be transplanted into individual pots or directly into the ground.
Division
Division can be done during the spring or fall. The mature plant should be dug up and carefully divided into smaller sections, with each section containing both roots and leaves. These smaller sections can then be replanted in their new location.
Stem Cutting
Propagation through stem cuttings can also be done during the spring or summer. Select healthy stems and cut them into 4-6 inch sections, making sure each section has at least two leaves. Dip the cut ends in rooting hormone and plant them in a well-draining potting mix. Keep the potting mix moist but not waterlogged, and place the cuttings in a bright but shaded area. Roots should start to form within a few weeks, and the new plants can be transplanted into their permanent location once they have started to grow.
