what plants are best for living wall

Plants are a great way to add beauty to the landscape outdoors or to add style indoors. However, there is a way to do it that saves you space by going vertical: a living wall. So, what is a living wall? A living wall is a wall that is covered with plant growth, which gives it the appearance of a hedge made of several different types of plants. A living wall may contain moss, herbs, succulents, vegetables, and vines. A living wall may use soil or a non-soil medium to grow the plants. What Is A Living Wall? A living wall (or green wall) is a wall covered with plant growth, giving it the appearance of a hedge. A living wall can contain all kinds of different plants, including moss, succulents, and vines. Many types of plants may cover a living wall, including: Moss (to cover areas between other plants)Herbs (you could create a wall with all the herbs you need for cooking!)Succulents (their low water requirements make them ideal for a low-maintenance wall)Vegetables (you could an edible living wall that you can harvest from!)Vines (flowering ones will add dazzling color to your wall) Living walls can stand alone indoors or outdoors. They can also be built on or near existing walls. Some living walls use soil as a growing medium. However, there are other possibilities for a living wall, including: Aeroponics (growing plants without soil using a nutrient mist system)Aquaponics (growing plants and fish together – think hydroponics + fish)Hydroponics (growing plants without soil by putting their roots in nutrient-rich water)Hydroculture Felt You can learn more about growing plants without soil in my article here. Usually, a green wall has plants rooted at all levels of the structure. Compare this to a green façade, which often has climbing plants rooted only at the base of the structure. Outdoor living walls (green walls) add natural beauty to buildings. There are lots of ways to build a living wall, and they offer many benefits to those who adopt them. What Are The Benefits Of Living Walls? Living walls offer many benefits to anyone who adopts these green structures: Better health at home (connection to nature, less anxiety, faster recovery).Cleaner air (plants can remove air pollutants)Increased workplace performance (reduced fatigue and tension).Soundproofing (some plants cancel noise quite well, and they can be used to create private quiet areas in an office).Cooler temperatures (plants reduce air temperature when water is evaporated).Easier access to fresh food (if you grow herbs or vegetables on your wall).Natural Beauty (adds to any indoor setting or outdoor landscape).Endless customization options (there are too many combinations and arrangements of plants to count!) This isn’t just my opinion! According to the Penn State University Extension, research suggests that living walls in buildings improve our health and performance. A living wall indoors can improve the health and performance of workers. Once you decide that a living wall is for you, it’s time to decide on which plants to include. What Plants Are Best For Living Walls? Some good plants for living walls include moss, herbs, succulents, vegetables, and vines. Moss For Living Walls Moss is more likely to grow well in shady, damp areas with acidic soil. So, moss is a good candidate if you want to put your living wall in an area without much sun. Moss grows naturally in the forest, but you can use it for a living wall. Moss is a good complement to any living wall. It is great for filling in the spaces between other plants in the wall. Since moss has no roots, it does not need much of a growing medium at all. It will gladly attach itself wherever you decide to put it (eventually). If you like, you can build a wall made entirely from moss. Verdure is a good place to start looking. Herbs For Living Walls You can try lots of different herbs for your living wall, but here are a few classic herbs you might like: Basil – great for pesto, caprese salad, tomato sauce, and lots of other dishes. It has an unmistakable aroma that will make you want to walk by your living wall as often as possible.Mint – there are hundreds of different types of mint, many with interesting flavors. You can use mint for tea and other drinks or for cooking. Mint can help to round out an herb wall with something a little sweeter.Rosemary – this herb has a nice aroma that adds something special to many dishes. Its fragrant needles make a good addition to a living herb wall.Lavender – the scent of lavender is desired by many for use in soaps, perfumes, potpourri, and essential oils. If you grow it on your living wall, prepare for a burst of purple color in addition to the nice smell.Sage – the grayish green leaves of sage add a distinctive appearance to a living herb wall. Its flowers can come in blue, purple, pink, and white, so there is no shortage of colors from this herb. Sage likes full sun and well-draining soil.Thyme – this pungent but pleasing herb is originally from the Mediterranean. It does not need much water, and it will eventually flower, attracting pollinators if your living wall is outside. Basil is great for cooking, and it adds deep green leaves with a great aroma to a living wall. Succulents For Living Walls Succulents do not need much water. In fact, they are well-equipped to handle extended periods of dry weather or drought due to their fleshy leaves that store water. If you want a living wall that doesn’t need much watering, succulents are a smart choice to include. Some succulents you might want to use for a living wall include: CrassulaEcheveriaSedumSempervivum Echeveria is a succulent that makes a good addition to a living wall.

Vegetables For Living Walls If you want an edible living wall that gives you food in addition to green beauty, consider adding some vegetables. Some of them will climb all the way up the wall, while others will fill in any empty spaces that appear. Some vegetables for a living wall include: Lettuce – the classic salad vegetable, lettuce can grow on a living wall. There are lots of different colors of lettuce available, including light green, dark green, red, and even deep reddish purple.Peppers – a relative of tomatoes and a nice plant to have on a living wall. They often will not grow as tall as tomatoes in a single growing season, but the fruit goes well with tomatoes and onions to make salsa.Spinach – this is a nice, deep green plant to fill in gaps in your edible living wall. It works great in salad, and for this reason, it is a good complement to lettuce.Tomatoes - smaller determinate varieties may work better for limited spaces. However, you can also plant taller indeterminate varieties at the base of the living wall and let them climb all the way up! Tomato plants climb up twine or stakes with their vines, but will also climb a living wall. Vines For Living Walls Vines are great because you can plant them at the base of a living wall and let them climb all the way up. Then you can put other plants in place to fill in any gaps. There are lots of options to choose from when it comes to flowering vines for a living wall: some tolerate shade, while others do well in full sun. Others have beautiful flowers in red, purple, white, and other colors. Here are some good choices for vines for a living wall: Blue Glory Vine – this is a perennial vine with showy purple flowers.
