Edible, Cold & Drought Tolerant Plant List for Western Colorado Landscapes & Gardens

 Edible Landscaping and Forest Gardening in the High Desert Steppes – Arid, Cold Climate

Forest gardening, or as I like to think of it, “Forage Gardening,” is a fun way to plan and plant your landscape. The main objective is year round abundance for all involved, the people, land, bugs and other critters.  The list below outlines many of the plants I am currently growing.

Guilds

Functional groups of mutually beneficial plants form a guild. Conceptually, guilds mimic the plant communities of ecosystems, but are focused around species that are useful for people. Most of the plants in my list seem to work well together. Comfrey, yarrow, lovage, clover and crown vetch are my main under-story plants. The shrubs and berries fill in above them with a fruit tree, mulberry or nut as the over-story. Here’s an example of a simple guild: comfrey around a pear tree with strawberries and asparagus underneath. This is a semi-drought tolerant guild.

Drought tolerant guild: mulberry with siberian pea shrub, nanking cherry, yarrow and crown vetch. (Watch out for crown vetch, it spreads!)

Getting Started with Perennials

Direct seeding is best in the fall or early spring as soon as the ground thaws. Transplanting can be done in the fall or early spring as well, however coniferous trees and some deciduous trees and shrubs require winter water and are prone to failure if planted in the fall and left without water.

All drought tolerant plants need water to get established. The only exceptions are the ones that are able to self seed and some cactus cuttings.

Plant Zones

For reliable cold tolerance choose zone 5, borderline is zone 6b, some frost risk and  protection required in some years in zone 6a. With ambitious micro-climate creation and protection, low-water zone 7 plants can survive, for example: figs, rosemary.

Cold and Drought Tolerant Plants

These are all plants which I grow at 5,600 ft in Western Colorado. Annual rainfall is 8-10 inches and winter temp extremes can reach -20F.  The top soil is mostly heavy clay, sometimes over shale, sometimes over caliche, sometimes over river gravel deposits. It is often very alkaline.

I use supplemental irrigation for establishment and to speed up growth. Most plants are also mulched when planted to suppress weeds, retain moisture and create long term fertility. Some earth works and structures are helpful: berm and basin for water retention. For trees, snow-fences or planting on the north side of structures can help keep roots moist through the winter and delay flowering to escape late frost.

Here’s the list of plants, in no particular order:

  • Apricot (Prunus armeniaca) – Plant from local seed  or see: Burnt Ridge Nursery and  Trees of Antiquity

    What a great list! Thank you for putting this together

    • Aaron Jerad · October 14, 2015 Reply

      There are more that deserve to be on the list and suggestions are welcome! Glad you find it useful.

    This list looks GREAT!!!

    Do you know of any similar resources for other states?

    Thanks,
    Seth

      Hi, thanks. It would depend on the state…

        Hi and thanks for posting this list.
        I live in Steamboat Springs Colorado and planning to create edible forest and orchards using beneficial plant guilds. Do you have further suggestions on nitrogen fixing trees that would survive this altitud?
        Are the plants and trees in your list all good for this area?
        I know most and use some already…..but I was wondering what your thoughts were

          Hi,
          You should double check the hardiness zones of the plants on this list, I am in 5b and I think Steamboat is going to be colder. In addition to nitrogen fixers on the list you could look at Black Locust as a great nitrogen fixing tree, which can be coppiced and is great for in-ground applications like fence posts. Also for your area: Alder, Lead Plant, Silverberry.

    Thank you soooo much this is EXACTLY what I’ve been looking for.

    One thing on list you DO NOT WANT to get started is burdock — invasive weed that goes crazy , terrible burrs to get out of any animal that gets in them or in your hair. Bees might love the flower stage but difficult to get rid of . Has long tap root that if you cut off or dig but don’t get most of it , it comes back double and can get very tall. Have to spray to kill and I don’t like spray.

    • Aaron Jerad · March 26, 2017 Reply

      Agreed that Burdock can go wild, however… I use a Japanese variety and control the seeds. In my climate it doesn’t really go wild, it still needs a little supplemental water to thrive. It is bi-annual, so not too difficult to control. I let it set seeds, then cut the main stalk and toss it to the chickens. For the benefits: food/nutritional, bee food, soil building and control of grass I find it is worth the work of keeping it under control.

      Crown-vetch on the the other hand… I may regret planting.

    I dont comment much on websites, but felt the need to say thanks for this list, there is precious little quality info on the internet about useful plants for high dry and cold. We’re at 3500′ in the Idaho panhandle. A bit lower and (theoretically) a bit more rainfall than you, but a bit colder too. I need to expand my plantings beyond locust and Siberian pea shrub and this has given me some nice ideas.

    Happy planting!

    Sir you left an amazing gift for the world in the list above thank you for the time and effort you have saves a lot of people time and headaches I am sure.
