catmint 'Porzellan'


Nepeta 'Porzellan', commonly known as catmint, flaunts a display of delicate, lavender-blue flowers that cluster on spikes atop the stems. The blooms are abundant and form a swath of cool, pastel tones throughout the blooming period. The foliage is a soft grey-green, comprising small, heart-shaped to oval leaves that are slightly serrated on the edges. They are aromatic when touched, releasing a refreshing, herbal scent that is characteristic of the Nepeta genus. The overall shape of the plant is mounding; it creates an undulating form that's filled with fine-textured leaves and frothy flowers. Catmint's growth habit makes it suitable as a border plant or as an accent in a perennial garden. It harmoniously combines with other plants, blending with a variety of garden color schemes and offering a soothing visual appeal.

  • skullToxicity

    • To humans

      Nepeta 'Porzellan', commonly known as catmint, is generally not considered toxic to humans. Ingesting small amounts of this plant is unlikely to cause any significant or harmful symptoms. However, as with any non-food plant, individual allergies or sensitivities could result in mild gastrointestinal upset if ingested in larger quantities.

    • To pets

      Catmint is known to be of low toxicity to pets. It is actually a plant that can have a stimulant effect on cats, similar to catnip, which is in the same genus. Cats may exhibit behaviors like rolling, pawing, or friskiness due to the nepetalactone compound in the plant. Dogs, on the other hand, aren't usually affected by this plant, and poisoning from the ingestion of catmint is rare. If your pet consumes a large amount, monitor for any unusual symptoms such as gastrointestinal upset, and consult your veterinarian if any concerns arise.

As needed
  • water dropWater

    Catmint should be watered regularly, especially during the first growing season to establish a deep, extensive root system. Once established, it is quite drought tolerant and needs less water. The soil should dry out slightly between waterings. As a general rule for established plants, provide about an inch of water per week, either through rainfall or manual watering. During the hot summer months or in particularly dry conditions, you may need to water twice a week, whereas cooler, moist periods will require less frequent watering. Avoid overhead watering to reduce the risk of leaf diseases.

  • sunLight

    Catmint thrives best in full sun, which means it requires at least six hours of direct sunlight daily. It can tolerate partial shade but will produce fewer blooms and may become leggy. Place it in a spot where it can receive ample sunlight for strong growth and optimal flowering performance.

  • thermometerTemperature

    Catmint prefers temperatures between 60 and 70 degrees Fahrenheit but can survive in a range between approximately 30 degrees Fahrenheit during the winter and up to 85 degrees Fahrenheit in the summer. It goes dormant in colder weather and can survive winter freezes, but it is susceptible to damage from intense heat paired with high humidity.

  • scissorsPruning

    Prune catmint in the late fall or early spring to maintain its shape and encourage bushier growth with more blooms. Deadheading spent flowers during the growing season can also promote additional blooms. The best time to cut back the entire plant is after the first frost in fall or just before new growth starts in spring.

  • circleLife cycle

    The Nepeta 'Porzellan', commonly known as Catmint, begins its life cycle when the seeds germinate in spring, requiring well-drained soil and a good amount of sunlight for successful sprouting. As it progresses to the seedling stage, the plant develops its distinctive grayish-green foliage and begins to form a compact, mounded habit. In the vegetative stage, the leaves continue to grow, and the plant starts to spread, reaching up to 24 inches in both height and width, depending on growing conditions. During the flowering stage, typically from late spring to early autumn, it produces spikes of small, lavender-blue flowers which attract bees, butterflies, and other pollinators. After its blooming period, Catmint sets seed, which can disperse to propagate new plants; simultaneously, it may also spread through its rhizome root system. Eventually, as winter approaches, Nepeta 'Porzellan' enters a period of dormancy, although it is a perennial and will rejuvenate and repeat this cycle when spring returns.

      Spring-Early Summer

    • The most popular method of propagating Nepeta 'Porzellan', commonly known as Catmint, is through stem cuttings. This technique is best performed in late spring or early summer when the plant is actively growing. Take a 4 to 6-inch (10 to 15 cm) cutting from a healthy, non-flowering stem, making the cut just below a node where leaves emerge. Remove the leaves from the lower half of the cutting to prevent rot. Dip the cut end into rooting hormone powder to encourage root growth, and then place the cutting in a pot filled with a mixture of peat and perlite or sand. Ensure the pot provides adequate drainage and maintains the moisture without being excessively wet. Place the pot in a bright, indirect light location and wait for roots to develop, which usually takes a few weeks, before transplanting into the garden or a larger container.
