Grasses, Ferns, and Groundcovers
​

This curated group of plants is used to add greenery to landscapes, cover wide areas of unused land, add color to otherwise monotone landscapes, and as fillers for empty spaces. This list has been divided into three groups: Grasses, Ferns, and Groundcovers. Read about each in their respective sections below.

Grasses

The following list of genera and species is a group of grasses and grass-like plants, used to add softness, structure, and form to landscapes. Grasses can be used in landscapes to cover large swaths of land with green, to give movement and height to tiered gardens, for contrasting color in beds and containers, and to line pathways and other hardscaped areas. Grasses are divided here into 5 general categories:
  1. Lawn Grasses: These grasses are commonly used for large or small areas and can be mown to just a few inches tall. This group includes Agrostis, Buchloe, Cynodon, Festuca, Lolium, Poa, Stenotaphrum, and Zoysia. Many of these grasses are found in lawn mixes, or are available as sod. 
  2. Groundcover and Meadow Grasses: These grasses range in height from 1 to 3 feet tall and are great for natural lawns or meadow landscapes. This group includes species of Festuca, species of Muhlenbergia, Nassella, and Sesleria.
  3. Sedges for Color and Texture: These are not true grasses, but are grouped with ornamental grasses because of their similar uses. This group includes plants like Carex and Cordyline, and some species can be used as lawn substitutes. 
  4. Small to Medium-Sized Accent Grasses: These grass-like plants have beautiful foliage or flowers. This group includes Alopecurus, Arrhenatherum, Briza, Imperata, Leymus, and Pinnisetum.
  5. Taller Grasses for Accents and Screens (Includes Bamboo): These plants are wonderful for creating natural screens, adding motion to gardens, and combine well with a wide variety of other plantings. This group is large, and includes Andropogon, Calamagrostis, Chasmanthium, Deschampsia, Elymus, Eragrostis, Hakonechloa, Helichtotrichon, Leymus, Melinis, Milium, Miscanthus, Molinia, Muhlenbergia and Oryzopsis.
The list below contains some of the most popular grasses and related plants used in gardens and landscapes in the Western United States.

Ferns

Ferns are plants that do not have flowers; they instead reproduce via spores. Most ferns produce fiddleheads, or curled, snail shell-looking new foliage that unfurls to reveal a new frond. Ferns are commonly used in woodland landscapes, to add tropical looks to beds and borders, and to create softness in gardens. Ferns can be groundcovers, low plants, larger shrub-like forms, or trees. Some species are also wonderful in pots and hanging baskets.

Groundcovers

By definition, a groundcover plant is simply a plant that grows over an area of ground and provides protection for the topsoil from erosion and drought. 'Groundcover' is interchangeable with the terms 'herbaceous layer', 'regenerative layer', 'ground flora' and 'step over'. The herbaceous layer is present in many landscapes, including those that are natural, and can contribute up to 90% of an ecosystem's plant diversity. Groundcover is crucial to the survival of many environments.

Groundcovers are usually smaller-scale plants that are great in areas that need weed suppression, and can add foliage and color to gardens with minimal maintenance. These plants improve the appearance of otherwise bare areas of the garden. There are five general types of plants that are used as groundcovers:
  1. Vines: Woody plants with slender stems that spread outward.
  2. Herbaceous Plants: Non-woody, low-growing plants.
  3. Shrubs: Prostrate or dwarf forms of many shrub species are used as groundcover.
  4. Moss: Coarse, large-leaved species are used as groundcovers.
  5. Ornamental Grasses: Especially those that are dwarf varieties or low-growing.

You may recognize some of the names below as plants that you know in their other forms - as shrubs or other perennials. These familiar genera include species that are great for groundcover purposes.
