Mazus

Mazus miquelii - A Low-Growing Ground Cover

Common Names: Creeping Mazus, Mazus, Miquel's Mazus

Previously known as: Mazus reptans

Mazus reptans is a versatile ground cover that offers a dense, attractive carpet of foliage. This low-growing perennial typically reaches a height of only two inches, spreading horizontally through creeping stems that root at the nodes. Its narrow, bright green leaves, which can grow up to one inch long, form a dense, evergreen mat that persists throughout the growing season and well into the fall.

Mazus is a genus of low-growing perennial plants native to New Zealand and Asia. They are known for their dense, creeping habit and small, colorful flowers.

The most common type of Mazus is Mazus reptans, also known as creeping Mazus or New Zealand Mazus. It is a versatile plant that can be used as a ground cover, edging plant, or container plant. It is tolerant of a wide range of conditions, including sun, shade, and moist or dry soil.

Mazus plants are typically only about 2-3 inches tall, but they can spread to form a dense mat that is up to twelve inches wide. The leaves are small and green, and the flowers are small and tubular, with colors ranging from blue and purple to white and pink.

Mazus plants are relatively easy to care for. They need to be watered regularly, especially during hot weather, but they are drought-tolerant once they are established. They also need to be fertilized in the spring with a slow-release fertilizer.

Mazus plants are generally pest- and disease-resistant. However, they can be susceptible to root rot if the soil is too wet.

There are two main ways to plant Mazus: from seeds or from plants. Each method has its own advantages and disadvantages, so the best choice for you will depend on your preferences and the specific conditions of your garden.

Planting Mazus from seeds:

  • Advantages: This is the most economical way to plant Mazus, especially if you need to cover a large area.
  • Disadvantages: Mazus seeds can be slow to germinate, and it may take several months before you see any results. Additionally, it can be challenging to get seeds to germinate evenly, which can lead to a patchy growth pattern.

Here is how to plant Mazus from seeds:

Choose the right time: Seeds are best sown in late spring or early summer.

  • Prepare the soil: Choose a location with well-drained soil that receives full sun or partial shade. If your soil is heavy clay, amend it with organic matter to improve drainage.
  • Sow the seeds: Scatter the seeds thinly over the prepared soil and lightly press them into the surface. Do not cover them with soil, as they need light to germinate.
  • Water regularly: Keep the soil moist until the seeds germinate. This may take several weeks.
  • Thin the seedlings: Once the seedlings have a few sets of leaves, thin them to a spacing of about 8-12 inches apart.

Planting Mazus from plants:

  • Advantages: This is a faster and easier way to plant Mazus than using seeds. You will see results much sooner, and the plants will be more uniform in size and appearance.
  • Disadvantages: Plants can be more expensive than seeds, especially if you need a large number of them.

Here is how to plant Mazus from plants:
