Creeping thyme, also known as Thymus serpyllum, is a versatile and low-growing perennial herb that can be propagated through various methods, including seed propagation. While it can spread by seed, it is important to note that the process may not always be reliable or result in consistent growth.
To propagate creeping thyme from seeds, you can start by collecting the mature seeds from the plant. This can be done by allowing the flowers to dry on the plant until they turn brown and develop small seed pods. Gently rub the pods between your fingers to release the tiny seeds. It is important to ensure that the seeds are fully mature and dry before collecting them.
Once you have collected the seeds, you can sow them directly into a well-prepared seedbed or seed tray. The soil should be well-draining and slightly moist. You can create small furrows in the soil and sprinkle the seeds evenly along the furrows, then cover them with a thin layer of soil or vermiculite. Water the area gently to keep the soil moist but not waterlogged.
Germination of creeping thyme seeds can take anywhere from two to four weeks, depending on the conditions. It is important to keep the soil consistently moist during this period to aid germination. Providing a clear plastic cover or using a seed tray with a transparent lid can help retain moisture and create a greenhouse-like environment for the seeds.
Once the seedlings have emerged and developed their first true leaves, they can be transplanted into individual pots or directly into the garden. It is advisable to provide adequate spacing between the seedlings, as creeping thyme tends to spread and fill in the gaps over time.
While propagating creeping thyme from seeds can be an exciting and rewarding process, it is important to be aware that the resulting plants may not always resemble the parent plant. Creeping thyme can cross-pollinate with other thyme varieties, which can lead to variations in the characteristics of the offspring. This can result in different growth habits, flower colors, and even fragrance.
Additionally, if you are looking for a more uniform and consistent appearance, propagating creeping thyme through division or stem cuttings may be a more reliable method. Division involves separating an established plant into smaller clumps and replanting them, while stem cuttings involve taking a portion of a stem and encouraging it to root and grow into a new plant.
Creeping thyme can indeed spread by seed, but the process may not always yield consistent results. If you are looking for a more predictable outcome, propagating through division or stem cuttings may be a more suitable option. Experimenting with different propagation methods can be a fun and educational experience for any gardener.
