Alpine Garden Plant List

The alpine garden was created in the fall of 2008. I have grown alpine perennials from seed and purchased some others from garden centers. These plants are all low-growing and good candidates for rock gardens. They are growing in full sun and in relatively poor soil. I will make notes of any plants that don't survive the winters, as growing alpine plants in zone 1 in northern Saskatchewan is a bit of a gamble in hardiness.

Many of the plants form low mounds. I hope for these little mounds to nearly coalesce and eventually form a nice carpet of plants around the rocks. I will keep adding plant photos to this list as the plants grow and bloom.
  • Acinos alpinus (Rock thyme)-- small purple flowers
  • Alchemilla alpina -- gift plant from local gardener, blooms in June. Spreads and can get a bit messy-looking if not trimmed back.
  • Allium flavum v. minus -- yellow flowers, bloomed July 20, 2009
  • Androsace primuloides “Sheppard” – died after planting
  • Arabis caucasica “Rosea” -- started from seed, bloomed early June
  • Arabis ferdinandi-cobergi “Variegata”--very attractive white and green foliage
  • Aster alpinus “Goliath”-- started from seed
  • Dianthus microlepsis white -- bloomed July
  • Cerastium alpinum ssp. lanatum – white flowers, grey hairy foliage, growing and spreading fairly fast
  • Delosperma nubigenum – yellow flowers, spreads very well
  • Delosperma deleeuwiae -pink flowers, from Wrightman alpines spring 2009, bloomed July 21, 2009
  • Draba mixed -- started from seed
  • Draba polytricha – very tiny, feeble as of June 09, but overwintered extremely well without any damage to its evergreen foliage. Yellow flowers April 2010.
  • Dryas octopetala “Alpine Carpet”- from Wrightman alpines spring 2009, overwintered well. Appears evergreen.
  • Erigeron compositus--started from seed spring 2008, bloomed July 20, 2009
  • Jovibarba small rosettes mix – started from seed, look like Sempervivum, overwintered well
  • Lewisia hybrids -- very pretty flowers, plants reliably hardy over several winters only if in well-drained soil. The ones in the alpine bed rotted in winter.
  • Lewisia cotyledon “Little Plum”, “Regenbogen”, plus Lewisia mix started from seed
  • Muscari armeniacum
  • Narcissus “Tete-a-Tete”-planted fall 2008
  • Papaver miyabeanum “Pacino” (Japanese poppy) – Self-seeds easily, with new plants starting to grow in late March.
  • Penstemon rupicola “Pink Holly” --arrived in the mail mostly dead
  • Saxifraga x arendsii “Peter Pan” – pink flowers, from Dutch Growers, overwintered extremely well.
  • Saxifraga x arendsii “Purple Robe”-- from Dutch Growers, overwintered extremely well.
  • Scabiosa japonica “Pink diamonds” – grown from seed, first blooms in 2008 on June 28. Cut off dead blooms after flowering season to keep it looking neat.
  • Scilla siberica (Siberian squill) -- tiny spring-flowering bulb with deep blue flowers. Looks good in dense clusters, naturalizes and multiplies every year. Plant tips emerging from the ground April 20, 2010.
  • Sedum kamtschaticum 'variegatum' -- red and yellow flowers, bloomed July 21, 2009. Winter hardy.
  • Sedum laxum ssp. laxum--grey and pink foliage, very slow to start growing
  • Sedum makinoi “Ogon” -- bright yellow foliage
  • Sedum ewersii (Ewers Stonecrop) -- grey-green foliage, grew well; pictured in spring
  • Sedum rupestre “Angelina”
  • Sedum spathulifolium “Cape Blanco”
  • Sedum spurium var. coccineum “Dragon’s Blood”
  • Sempervivum (Hens and chicks) – various types
"Cobweb" hens & chicks"Ashes of Roses"

  • Thymus pseudolanuginiosus (woolly thyme)
  • Thymus serpyllum (creeping thyme)
  • Thymus serpyllum “Elfin” -- the most low-growing, compact thyme I have ever seen
  • Lemon thyme -- gift from family member, variegated fragrant leaves
  • Veronica allionii
  • Veronica armena – from Wrightman alpines
  • Veronica whitleyi -- from Dutch Growers in Saskatoon
  • Actostaphylos uva-ursi (Bearberry). Foliage turns burgundy in fall/winter.
  • Dwarf balsam fir. Minimal winter damage, with some brown needles in spring 2010.
  • Dwarf mugo pine. Almost unaffected by winter damage.
  • Nest spruce. Very little winter kill, but had good snowcover and little wind.
Ideas for more plants to try in the alpine garden:
  • Phlox douglasii, Phlox borealis
  • Silene uniflora 'Druett's Variegeted

It looks like it will be lovely!

Everything is amazing, can you grow Lewisia from seed? Oh wow, I never thought to check that out. And do you overwinter outside or in?

Living in a small condo my seed starting choices are limited to very few. I love Lewisia, but have balked at paying the price for them, to perform as annuals, since I did not think that they would overwinter here, too wet.

I am excited!


Gardenista said...

Yes, I grew Lewisia from seed. I can't say it was easy. They require cold stratification in the refrigerator for a few months followed by warm conditions. I still have a few coming up after a few months on the warm shelf under lights. Yeah, I don't know that they would do well as waterlogged plants, since mine live in fairly well-drained locations over winter. They are very hardy here.

Wow, what fascinating little plants! I love the foliage.

Jamie Keifer said...

Wow! I can just imagine how these flowers would bloom between the rocks. It would be full of colors and life! I can almost see the rock thymes growing with its purple color. The creeping thyme would be a charming groundcover with its pink flowers spreading throughout the soil. I just love the flowers you've chose in this garden. It's full of TLC. :-)

We are moving to La Ronge in a few months and this info is going to be so useful. Thank you!

It’s really a feast for the eyes when in full bloom, seeing the flowers in your collection! They’re interesting and providing a blog exclusive to this is definitely worthwhile. You’ll see how it has grown through the years! :] And it serves as a place to document your mistakes and successful attempts as well. After all, we know alpine gardening requires the ‘trial and error’ approach.

Shona Martinez said...

I love Elfin Thyme! We have a lot of it in our garden! They really look so wonderful and aside from that, they are really fragrant! :’) These flowers are beautiful especially when they bloom during the summer!

I have just created a rock garden at the front of my home as it is impossible to grow grass without using gallons of city water. This article is extremely helpful as I choose the plants to soften and "naturalize" this part of my water wise garden. Thank you.

Rockery plants for shade said...

I have another list here with rockery plants that will tolerate shade, because many friends and colleagues have been interested in the subject. It's a common misconception that alpine plants only like direct sunlight. It would be awesome if you gave me some feedback! :)

Thanks, Gena
