Note: Comments on edibility/medicinal use etc are generally taken from internet references, and should be considered only a starting point for further research. Before using any plant, be certain of identification and learn about all potential toxicities: traditionally used plants are not always in favour in modern times, nor suitable for all people!
Androsace septentrionalis / Northern Androsace / Pygmyflower Rockjasmine
Native; fairly broad range, I think my original plants were from the foothills, but not sure; annual (winter annual) to short lived perennial (reflowering plants tend to flower close to the rosette--perhaps if you selected seed of reflowering plants you could select for perennial low flowering plants over time?); small flat rosettes of greyish to medium green leaves add interesting low texture, with some added interest from reddish colour in cold seasons. Small white flowers in open clusters start low, then stems extend variably (depending presumably on site, but also individual plants) 10-20 cm or so, reaching maximum height in seed as the plant is dying generally. At that stage the stems and seed heads also turn reddish colours, making the dead plants attractive. Should reseed itself, but never problematically here (plants are small and easy to remove).
Betula pumila / Bog Birch / Dwarf Birch
Native; multi-stemmed shrub 1-4 metres height, they say-- hard to judge here as they are typically browsed, often heavily, by cattle and moose--commonly around 2m or so here; Small, toothed leaves, attractive, variable fall colour. Native to wetlands, I expect they'd be adaptable to regular garden conditions.
Comarum palustre / Potentilla palustris / Marsh Cinquefoil / Swamp Cinquefoil / Purple Marshlocks
Native; One of that vast and often appealing tribe in Rose Family: Potentillas past and present. This is a wetland/ edge plant, sometimes growing partly submerged, but also in soils only seasonally wet, so I suspect it has a good chance of adapting well to garden conditions. Stems are rather sprawling. growing through low woodies, other forbs etc (not so different to P. nepalensis etc popular in gardens). The burgundy/wine coloured flowers have an unusual look due to the pale tipped pointed sepals being longer than the dark petals. Like many Rosaceae, there is also often good fall colour.
Gentianella amarella / Northern Gentian / Felwort
Native; medicinal; Annual / biennial; a widespread species, with regional variants. Delicate, elegant plant, here they are roughly 30-40cm tall, very narrow plants, with narrow tubular flowers, open only on the end. Generally moist to mesic areas, open grassy places or woodland edge, overlapping with Halenia, but tending to slightly more open sites Mid-late summer flowering here.
Geranium ex ex G sanguineum Elke / Dwarf Bloody Cranesbill
Two exes, because my plant, bought as Elke from a mainstream vendor either clueless or unethical, clearly wasn't, probably grown from seed from Elke. This seed is from that plant, so at least two generations removed from the cultivar. Nonetheless a nice little plant, staying low and flowering over a long period, good clear strong pink flowers. Rock garden or low border.
Geranium richardsonii / Richardson's Geranium / Wild White Geranium
Native; Variable standard form-- flowers are white with pink-purple lines; occasionally all white to nearly a pink effect; airy, but mostly erect, rather open growth depending on site (from full sun mesic to deep shade moist to dryish); Scattered good fall colour; (30) 40-60 (80)cm.
Gypsophila repens 'Rosea' / Pink Alpine Gypsophila / Pink Creeping Baby's Breath
Rock garden or sunny, well drained border; Loose mats of tiny grey-green leaves, to around 15cm (according to several sources; I think it may be more like 20cm in my garden, which is not terribly exposed. Could be a bit too exuberant for really small gardens, or next to small choice plants, but with masses of good pink flowers in early summer, and lighter flowering after, it is well worth it if you can spare a little space; can also be clipped back to help contain it.
Leibnitzia nepalensis / Himalayan Sunbonnets /Chinese Gerbera
Possibly edible, and used in Asian medicine; An interesting genus, but don't let the name Gerbera confuse you: these have been included in the genus Gerbera in the Daisy Family, but have little casual resemblance to the flashy florist's Gerberas! These plants begin in spring (not too early, here) with small, short stalked thickish leaves and a few whitish daisy like flowers (mine are not prolific, but it may depend on site, and varies by year, as well). As the season goes on, it produces larger leaves on much longer petioles, and then many cleistogamous flowers (i.e.- they do not open, and are self pollinating). These flowers produce fluffy seed heads into fall, which are in fact, the showiest things about it. The pappus (fluffy part) starts off rusty coloured, tinged at times with violet, fading to a reddish tan. I try to leave them for a while, and never get them all collected, but they will self sow if you let them (seedlings are easy to remove where unwanted). This is a plant of high elevations, and while, at least in my not hot summer climate, they appreciate sun (light shade should be okay- maybe late emerging plants that would shade in summer would be nice neighbours), they like to have their roots cool, and not too dry, it seems, so I've moved them to spots where the soil -but not leaves- is shaded by rocks, wood, slight slopes, etc.
Mitella nuda / Naked Miterwort / Naked Bishop's Cap
Native; abundant prostrate woodland groundcrover, growing from part sun to deep shade in a variety of soils and moisture profiles, probably prefers mesic to moist. Rounded heart to kidney shaped leaves crenate (scalloped) edges, slightly hairy, on groundhugging stems. Tiny intricate flowers on erect stems 10-20cm tall. the effect en masse is delicate and feathery. In the wild here they rarely get much real estate to themselves, growing with, under and among many other species. In the garden it could be quite vigorous, making a nice groundcover that you might want to keep separated from small delicate plants, I *think* spring bulbs or larger perennials should be able to grow through it, and of course you could clip and thin it as needed. Would be lovely tumbling among and over rocks and logs, stumps.
Paederota bonarota / Common Bonarota / Blue Bonarota
European alpine, herbaceous, easy in my garden in gravelly clay among rocks; took a few years for flower clusters to get large enough to be showy, but it is better every year, with some nice fall colour too. My first year trying to collect seed, tiny seed hard to clean-- I managed to get enough for a couple of packets.
Polemonium boreale cf P.b. Heavenly Habit / Jacob's Ladder
I received this as seed of simply Polemonium boreale-- visions of the ground hugging delight of the arctic came to mind. This isn't that. What it is, is something more like the Polemonium cultivar Heavenly Habit. A very nice plant for a meadow or border, or section of a rock garden with moderately large plants. Here it is probably 30 -40cm tall on average, taller than wide, with erect stems. It can grow in very tough conditions-- dry and exposed-- where it will be much smaller, but still vertical. Flowers are a good size and strong colour, and borne for much of the season. Popular with pollinators as you can see in some of the photos. Decent fall colour.
Primula florindae/ Himalayan Primrose
robust plants with large strap like medium/deep green textured leaves, mix of yellow and orange flowered plants.They can grow to 120cm, they say, have not done so here, maybe half that at most-- wetter, richer sheltered locations would likely give bigger plants. Roots need to be kept cool and moist; part shade or more for the foliage, depending on moisture. I'm sure they'd love a streambank- I don't have one, so (in the part day sun woodland clearing) I dug well below grade and added peaty humus from native wetlands, added a low ridge of wood and soil in front to add shade, and mulch with leaves and grass. I keep an eye on them during dry spells in spring and mid-summer. Better moisture would give fuller flower clusters than you see here.
Saussurea riederi / Rieder's Saussurea / Japanese Saw-wort
Asian sub/alpine; I've presumed it prefers moisture, based on the little info I could find about habitat, but it may not be that fussy. Unlike some in the genus, soundly perennial. Attractive plant with tallish leafy stems, thick leaves, lightly hairy; good sized flat clusters of pink-purple flowers, mid-late summer, much loved by bees. Some nice fall colour in the sombre shades. Rhizomatous- after a handful of years in ground, starting to spread- not super long stolons, but spreading clumps and some offshoots a small distance away-- should be given space, and/or grown with other robust plants. Good with spring bulbs, as it does not leaf out very early.
Sempervivum mix / Hens and Chicks
Seed collected from a number of species, cultivars, hybrids, open pollinated, should give a range of rosette sizes and various colours of leaves and flowers.
Sibbaldiopsis tridentata / Potentilla tridentata /Three-toothed Cinquefoil
I believe this species occurs in Alberta, and many other places--but my original seed was from Eastern Canada; it is said to like dry and rocky places, mine is in a gravelly berm, probably medium dry, but I imagine there is moisture below if it can send roots that deep... my suspicion-- but it is only that- is that in hotter, drier places, a bit of shade might help. In places with lots of summer rain, it is happy in sunny, rocky places. Spreading via rhizome, you might want to keep it away from small delicate plants, but the bright green foliage and sprays of small white flowers are nice en masse, and they can add a great shot of bright colour to the rock garden in fall.
