  • circleLife cycle

    Veronica austriaca subsp. teucrium 'Royal Blue', commonly known as Austrian Speedwell or Large Speedwell, begins its life cycle as a seed, which upon germination develops a root system and a rosette of basal leaves. In the following growth stage, stems elongate, and foliage increases as the plant matures. The next significant stage is the flowering period, usually in late spring to early summer, when it produces spikes of vibrant blue flowers that attract pollinators. After pollination, the flowers develop into small capsules containing seeds that mature, dry out, and finally release the seeds into the surrounding environment. The plant may enter a period of dormancy during the colder months, particularly in colder climates. Year after year, if conditions are suitable, the plant can re-emerge from its rootstock, repeating its life cycle, and it can also spread through self-seeding.

      Spring-Early Summer

    • The most popular method of propagation for Veronica austriaca subsp. teucrium 'Royal Blue', commonly known as Austrian Speedwell or Royal Blue Veronica, is by division. Division is typically done in early spring or fall. During this process, gardeners will dig up a mature clump of the plant and gently pull or cut it apart into smaller sections, each with several shoots and a healthy portion of roots attached. These sections are then immediately replanted into prepared soil, ensuring that they are spaced appropriately to accommodate the mature size of the plant. Care should be taken to maintain adequate moisture and to avoid planting too deeply—keep the crown of the plant at soil level. This method stimulates fresh growth and can rejuvenate an older plant, often leading to flowering in the subsequent growing season.
