Make It Green Garden Center

Welcome to our plant search tool. This database contains many of the thousands of plants that we carry. There are some notable exceptions. Hundreds of new perennials come out every year and Make It Green has been a leader in making them available to you. Eventually the recent introductions will make it to our plant search tool but every year there will be a lag between our in-store plant selection and this search tool. Unfortunately this search tool can't cover everything that we will carry this year. We also carry over 100 varieties of rare and unusual evergreens and over 100 varieties of hard-to-find shrubs many of which are not in the plant search. Click on the Plant List button for a list of nearly all the woody plants (trees, shrubs and evergreens) that we have ordered or already have in stock for this coming year.

Landscape Attributes

Silver Edged Horehound is a dense herbaceous perennial with a ground-hugging habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a relatively low maintenance plant. The flowers of this plant may actually detract from its ornamental features, so they can be removed as they appear. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Self-Seeding

Silver Edged Horehound is recommended for the following landscape applications;

  • Mass Planting
  • Rock/Alpine Gardens
  • Border Edging
  • Groundcover
  • Container Planting

Planting & Growing

Silver Edged Horehound will grow to be only 6 inches tall at maturity extending to 8 inches tall with the flowers, with a spread of 20 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 16 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.

This plant should only be grown in full sunlight. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is particular about its soil conditions, with a strong preference for sandy, acidic soils. It is somewhat tolerant of urban pollution. This species is not originally from North America..

Silver Edged Horehound is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our store for more information on how to protect it over the winter months.

This plant is not reliably hardy in our region, and certain restrictions may apply; contact the store for more information.
