Growth Facts

Irish Moss

Sagina subulata 'Crispy'
A low-growing evergreen Spirit to clothe bare ground and soften edges. Flowers, too!

This plant is not available at this time through Bower & Branch. Bower & Branch provides this information for reference only. Please click here to be placed on a waiting list. See below for other selections.

As green as that famous Emerald Isle, Crispy Irish Moss is a vibrant groundcover that holds its rich color all year long. Its fine-textured leaves bring lively greenery to blank spaces even in the depths of winter. There’s nothing Crispy about it, either. The poorly named “Crispy” Moss is as soft and inviting as a plush carpet, and you’ll want to take your shoes off and wiggle your toes in it. Go ahead! It can handle some foot traffic. This sweet little creeper is perfect for planting in between stepping stones or along a pavestone path.

Growth Facts

The Story

To a botanist, Crispy Irish Moss is very different from the mosses you find growing in the woods. However, the look both give to the landscape is similar. Irish Moss imparts a serene and welcoming feel to garden spaces and softens hard edges. This useful groundhugger is native to much of Europe and can be found in the wild from Iceland to Romania. It grows in situations where drainage is excellent but rain comes regularly. If you can replicate these conditions, you may want to grow it on a larger scale—maybe as a section of “lawn” that you never have to mow.

The Details

Crispy Irish Moss earns its keep with its foliage alone, but in late spring you’ll get a bonus when scores of miniscule, white, five-petalled blossoms spangle the foliage like stars in the night sky. You’ll know then that this is no ordinary moss. Irish Moss is actually in the Carnation family.

How to Grow

You may be able to grow Crispy Irish Moss in full sun if you live in a cool northern climate, but in most cases, you’ll want to shade it during the hottest part of the day. A need for regular water on one hand and excellent drainage on the other can make this Spirit a little fussy, so take the time to prepare the soil properly and irrigate during dry spells for best results. Another thing you may notice is that plants may mound up in the center, causing the roots to lose contact with the soil and brown spots to appear. Periodically step down lightly on plants that have raised themselves up to prevent this.

Step by Step Guide:

  1. Once you have your location chosen, place your still-potted plants to be sure you get them right where you want them. It always best to mitigate placement issues before you’ve started to dig.
  2. At this point , remove one plant at a time, digging where that plant was with the intention of making the hole a tad wider that the pot, but just a bit more shallow. The reasoning is this: ground soil is much more compact than planting media and so roots can have a difficult time spreading from on type of soil to the other. We use this empty space to backfill (more on this in a moment) with your worked soil, Bower & Branch Elements Composition Planting Mix, or a combination of the 2.
  3. Remove the plant and all tags from the pot and start loosening those roots! You don’t have to be overly aggressive, nor decidedly more delicate – use your best judgement to determine how much effort this step will take. The main idea is to encourage the roots to grow outwardly instead of retaining the shape of the pot itself. If you have a lot of tougher, thicker roots give it a little more elbow grease.
  4. Place your newly tussled root ball in the soil, making sure to center it and put its best side (face) forward. This is where the back fill portion of the instructions come in. Using the Elements Composition , start by putting a small handful in the bottom of the hole. We want the top edge of that root ball slightly above ground level. This ensures your roots won’t be saturated with water, which occurs when plants are planted too deeply.  1 to 2 inches is usually sufficient. Then we’ll use the remaining media to fill in the area between the root ball and the ground soil. Once your new plants are installed to your satisfaction be sure to water them in – a quick drink to hold the plants over until your regularly scheduled watering time.
  5. Lastly – apply Elements Composition as your MULCH!! Not only is mulch aesthetically pleasing, its also as much about function as form. A nice layer of high quality mulch keeps weeds down and helps to retain moisture in the ground.  Elements Compostion is even beneficial on a nutrient level as they break down throughout the season and release those nutrients in to the soil below!
