  • circleLife cycle

    Nepeta 'Hill Grounds', commonly known as catmint, begins its life cycle as a seed, often requiring a cold stratification period to break dormancy. Upon germination in the spring, the seedling emerges and develops into a small plant with distinctive, aromatic foliage. As it matures, catmint enters a vegetative stage where it focuses on leaf and stem growth, preparing for flowering. Throughout late spring and summer, it produces spikes of lavender to blue flowers that attract pollinators such as bees and butterflies. After flowering, catmint sets seed which can be dispersed to produce new plants. Once the growing season ends, catmint becomes dormant, with the root system surviving the winter to resprout the following spring.

      Spring-Early Summer

    • Catmint, known scientifically as Nepeta 'Hill Grounds', is typically propagated through stem cuttings. The best time for this practice is late spring or early summer when the plant is actively growing. To do this, select a healthy, non-flowering stem and cut a 4 to 6-inch (10 to 15 cm) length, making sure to include several sets of leaves. Remove the leaves from the lower half of the cutting and dip the cut end into rooting hormone to encourage root development. Plant the cutting in a well-draining soil mix, water it well, and cover it with a plastic bag to maintain humidity. Keep the soil moist but not soggy, and in a few weeks, new growth will indicate that the cutting has successfully rooted. Transplant the new catmint plant to the desired location once the roots are well-established.
