Landscape Attributes

Irish Moss is an herbaceous evergreen perennial with a ground-hugging habit of growth. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

This is a relatively low maintenance plant, and usually looks its best without pruning, although it will tolerate pruning. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Spreading

Irish Moss is recommended for the following landscape applications;

  • Rock/Alpine Gardens
  • Border Edging
  • General Garden Use
  • Groundcover

Planting & Growing

Irish Moss will grow to be only 1 inch tall at maturity, with a spread of 12 inches. 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 does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. Consider covering it with a thick layer of mulch in winter to protect it in exposed locations or colder microclimates. This species is not originally from North America. It can be propagated by division.

What Our Clients & Customers Say

To Marc and the crew at Wagner Landscaping,
Just short note to thank you for the quality craftsmanship you delivered at our Jefferson City residence. Our home was cut into a steeply sloping lot necessitating the need for considerable water management and erosion control landscaping. The sculpturing, erosion matting, retaining wall and ditch work was completed in short order, getting us ready for the winter. We are confident that when the snow melts and the rainy season comes next year our property will be ready to handle it. Thanks and best wishes to all.

– Steve Wilhoit –

Dear Chris,
I hope this is the greatest letter of recommendation you’ve ever received – I know it won’t be your last. To anyone who reads this, I can say without hesitation that Chris Wagner should legally change his name to Mr. Boulder! (Just one look at his hands will confirm that this title has been earned.) Chris and his team tackled a very remote project for us with hustle, integrity, imagination and great execution. We couldn’t be happier with the results. If Chris says “it” – “it” happens! We are happy to enthusiastically recommend one of the finest individuals with whom we have worked.
Sincerely,
William W. Nicholson
