Perennials in Montana

Perennials are flowering plants that come back every year as opposed to annuals which die off every year. Some flowering plants are perennials in warmer climates but annuals in colder climates. Below are some perennials that do well in Billings Montana and in some cases colder places in Montana. Billings Montana is in zone 2-4, however, some zone 5 plants seem to do well here. Much of Montana is zone 3 so it just depends on how much cold the particular species of plant can handle.

Here is a list of our favorite perennials for full sun

  • Salvia – A large perennial with purple spires of densely packed buds. Salvia get up to 3′ in diameter and 2 feet tall.
  • Coneflower Echinacea – There are several varieties available. These perennials handle arid climates and can be planted with yucca. They get over 2 feet tall and look very nice in combination with many other taller flowers like Black-eyed Susans.
  • Black-eyed Susans – These are a choice flower for bright yellows.
  • Yarrow – A native perennial that comes in many colors but usually yellow, white, or red and has medicinal properties.
  • Shasta Daisy – These are tall and lush with white flowers and yellow middles. We like to plant them near water features or areas that are more lush as opposed to arid areas.
  • Daylily – Lush wide bladed grass with nice summer and/or fall blooms. A variety of colors are available depending on species. They are great when planted at the base of boulders and stone walls or in lush areas. They will spread if allowed.
  • Butterfly bush – These gorgeous perennials grow 3-4′ and can be purple, hot pink, royal red and more.
  • Foxglove – interesting purple flowers
  • Delphinium- These tall perennials grow 3-4′ with gorgeous tall flowers. They come in many colors. Some varieties include black eyed angels, pink punch, and million dollar blue. We usually plant them next to the house areas that are more sheltered from the wind.
  • Dianthus – These are a favorite for bringing color around the landscape. They are a smaller perennial that handles arid climate very well yet yields continuous buds Spring, Summer, and Fall. They come in all sorts of colors and varieties. We like the hot pink!
  • Columbine is another native perennial that has more of a clover like leaf and beautiful flowers. It is also the Colorado state flower.
  • Jacobs ladder – This perennial can get fairly large and usually is known for its awesome blue flowers however it comes in varieties such as light purple.
  • Potentilla – Another yellow flowering perennial that is great in the front of beds because it only gets about 3″ tall. Not to be confused with the shrub, these perennials are important when yellow is the color of choice.
  • Phlox – If it is spring color that you want, Phlox will always please. The low growing Phlox comes in many bright colors, even brilliant blue! The flowers form densely clustered mounts. Some varieties of Phlox get tall and can be used as cut flowers for inside, but we prefer the low growing mounds for creating focal points of bright color.
  • Woods light blue Aster – light blue with yellow middles- 12″
  • Butterfly flower – asclepias- orange- 15″
  • Splendens- pink- 6″
  • Bellissima- light pinkish white with yellow middles- 6″ (English daisy) or (bellis)
  • Catmint- Can grow quite large and 18″ tall with lavender flowers.
  • Primrose- 8″ mixed colors
  • Beebalm- red and other colors. Beebalm is an herb used for teas. It does best with plenty of moisture.
  • Lupine- A native plant with cool looking conical flower buds, usually in pink and purple. These perennials handle more arid climates and can be found all over montana. The cultivars varieties are much more exquisite than the native Lupine while remaining very well acclimated to our climate.
  • Coreopsis- yellow space 1-3′ also orange
  • Cerastium- Also known as “snow in summer” this plant mounds up with dense blankets of white. Foliage is light green. Handles arid climate and works nicely with Phlox.
  • Heliopsis- yellow flowers, variegated leaf- 16″
  • Stonecrop sedum- 16-22″ tall with thick tissue leafs and impressive flower clusters. These are cool perennials! And sedum is a native plant here in montana so they handle the climate here very well.
  • Sedum- lemon ball – yellow ground cover. There are actually lots of varieties of ground cover Sedum. They really do best with full sun.
  • Geum- orange – 15″
  • Guara- pink and white- reddish foliage- 20″
  • Oriental Poppy
  • Peone – These come in two varieties. In particular, the variety with single stemming is more like a shrub and can be very spendy, but the flower clusters are huge. Best in more sheltered areas. Most commonly white or pink.
  • Veronica – tall spires bloom in the fall.
  • Aster – Medium to large size with lots of flower buds that open in the fall. Varieties of colors!
  • Artemisia – Soft to touch, light green color mounds. Blooms in the fall. We like to use this in the front of beds and next to seating areas where you can touch them. They also work nicely to soften the foot of perennials that do better when the base is shades, like with Clematis.
