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!

Achillea millefolium ex Terracotta
This hybrid, taller, with narrower stiffer compound leaves than some varieties, is supposed to be sterile, but I have seedlings coming up near it, with its distinctive foliage! Flowers begin orange, fade to gold. tough, adaptable plants, with uses in herbal medicine. I haven't yet knowingly seen any crosses between this and the local white flowered plants or pink A. sibirica camtschaticum. . It is not growing near the pink and red millefolium.

Allium aflatunense/ Allium hollandicum / Persian Onion/ Purple Sensation Allium
A popular garden Allium, of uncertain heritage,--as I grasp it, correct me if wrong!-- long known as aflatunense, this is likely wrong, so it has simply been called A hollandicum, for its centre of cultivation in the bulb fields of the Netherlands. Large balls (4" or so) of bright red-violet flowers, much loved by bees. 50-80cm or so tall, in my garden. Early leaves are tulip like, foliage fading by the time of flowering, so plant with something leafy to fill in and hide the yellowing leaves.

Anemone virginiana var cylindroides/ Tall Thimbleweed;
Native (common on the acreage, self sows into garden beds at the drier end , but never problematically). Another plant at it's showiest in fall (rich, subtle fall colour) and winter-- seed heads are masses of fluff for a while, with a bit left to show through the snow..native on the acreage and left/encouraged in some places in the garden; unlike some thimbleweeds, this one tends to drier sites, sun or shade. Flowers are smallish, greenish white; 30-60cm or more.

Androsace (carnea ssp) halleri/ Haller's/Pink Rockjasmine
Delightful alpine from the Vosges Mtns in eastern France. Compact tuft of green leaves, strong pink flowers on stems +/-10cm in spring. First year flowering for me, in gravelly clay in a mesic bed (Semp Bed 2) lots of stems already as seen in the photos.

Antennaria cf A. howellii Native; much larger rosettes than the small silvers, 2-3inches across; I have two slightly different forms, which may partly vary based on habitat: locally, they grow in semi/shade, under trees, clearing edges under grass, etc. Upper leaf surfaces are dark green, backs white/hairy. The other is from the foothills, very similar, but upper leaf surfaces are a greyer green, growing in more exposed sites, and very drought tolerant. Sometimes showing nice colour in cold weather. Flowering is typical for Antennaria, lengthening stems, whitish flowers, earlier than the silvers.

Antennaria -Small Silvers Native; the taxonomy seems unresolved, a good excuse for me since I have no grasp on it! This seed is from small rosette, mat forming silver leaf types-- I have several original collections from the foothills and mountains, and there are local plants as well. They seed around the garden. so I have no idea what is what, but all are basically the same, with whitish flowers. Rosettes stay small, and growth is tight in a variety of conditions (don't mistake flatness for meekness-- they will bury other small plants!) but you'd probably need a really tough spot to get the rosettes as tiny as they can be in nature. Shots from several sites in the mountains/foothills. These should all have whitish flowers, with some variation for male/female, stems elongate after flowers mature. Self sows quite generously, but never hard to remove unwanted seedlings. Attractive ground cover in garden beds or moderate traffic lawn/ mowed areas.

Antennaria rosea ex cult-Pink Flowering Pussytoes

From a garden centre plant of unknown provenance; Flat spreading mats of silvery leaves (like above); flowering stems rise in spring with soft pink (pale to medium-- I have a suspicion that soil may affect intensity of colour, but not sure of how) tufts of flowers; flower stems lengthen after maturity; attractive ground cover in garden beds or moderate traffic lawn/ mowed areas.

Anthyllis vulneraria/Kidney Vetch medicinal/tea-- had I known about the tea at harvest time, I would have saved more of the flower heads! Up to 40cm, somewhat sprawling plant; Generally for sun, well-drained soil, I haven't grown it long yet, but I don't think it is too fussy, no doubt more compact in leaner sites. Seed collected from a yellow flowered plant, there was a red not too far away, not sure if they cross; loose mound of spreading foliage, many clover like flower heads.

Aquilegia formosa/ Western Red Columbine ex B.C. seed
deep orange flowers, smallish plants (so far!)..there are other Aquilegias around, though not right beside, so can't be guaranteed to be pure as Columbines are known to be promiscuous.

Aquilegia formosa/ Western Red Columbine

Aquilegia Xeric Bed Hybrid
These spontaneously appeared several years ago, not sure what the origin is--possibly my mom or aunt had some Columbines near here in years past.. There is a native blue and white in Alberta, but I've never seen it, doesn't seem all that likely.. I grew formosa nearby long ago, and there were surviving plants not too far away; other plants farther on the acreage do not make these colours..Plants so far have either small blue and white flowers or larger wine and gold; super tough plants growing in mesic and dry spots in the garden and in very dry shade under a large spruce (where they first appeared). I've only seen these two forms in this patch so far, but as usual with hybrid populations, no guarantees!

Armeria/ Sea Thrift-mix from pink *or* white flrs
I had the small A. Victor Reiter and a regular sized A. maritima alba; Victor Reiter has died out, the alba is still doing well, and there are numerous seedlings of various sizes in both pink and white; I've collected seed from white and pink plants separately, and a later collection together, but wouldn't count on them coming true to colour. You can specify one source or mixed. These seem unfussy here growing in rocky spots and other sites that have more (still gravelly clay) meadowy conditions. Main flowering in spring, with flowers all season. Apparently Armeria is notorious for a high percentage of empty seed, so unless sorting proves fruitful, I'll just send large packets to improve odds.

Arnica angustifolia/Narrow-leaf Arnica /Arctic Arnica/Alpine Arnica;
Native; (Still some debate about the name, but no better match at the moment). A small Arnica, seeds collected from a gravelly roadside in the foothills near Nordegg; seems it is a species more typical of the alpine zone, I was lucky to find some seed farther down....., I thought it was a dryish site , but that may have been mistaken-- it tends to rain more there than here, and the plant doesn't seem thrilled with dry conditions in the garden.. Not rhizomatous to any notable degree, so it has not been a spreader with several years or more in the garden; flowering stems with very reduced leaves, 30cm or less, fuzzy grey-green basal leaves persistent. Late spring/early summer flowering.

Arnica angustifolia/Narrow-leaf Arnica /Arctic Arnica/Alpine Arnica

Arnica chamissonis/ Meadow Arnica /Silver Arnica/ Chamisso's Arnica
(presumably named for Adelbert von Chamisso, a German botanist who did field work in California in the early 19th century)
Native; medicinal; native species have similar properties to A. montanum, and chamissonis is cultivated for medicinal use; wild locally, moist-mesic sites, large robust Arnica 50-80cm, rhizomatous, nice silvery hairy foliage, almost like a small sunflower; mid-summer here; give it space to spread or be ready to control, but you'll want to let it make lots of stems-- you'll need lots of flowers if you want to use it as medicine, and as an ornamental they look great en masse!

Sedum, Phedimus, Aizopsis - A Stonecrop By Any Other Name?

Sedum is a genus with a long history of decorative, medicinal and edible use, well known to many gardeners, with long popular plants for physic gardens, rockeries, walls, rooves (including modern style green rooves), perennial borders and houseplant collections. It is also one of those huge old genera packed full of hundreds of not always very closely related species. As studies have continued over time, including genetic studies in recent years, many plants have been separated out into smaller genera, including some important in gardens such as Hylotelephium ( often late flowering, herbaceous plants, such as Autumn Joy), Phedimus (typically partially deciduous, low-growing ground covers, such as the spurium types, with serious flower power). These changes are not universally known or accepted, so you will still see the plants often labelled as Sedum. Now here is where our subject for today gets a bit more controversial: Phedimus. As mentioned, this genus is the home of a number
