Highlights from Wasatch Mountains

 Just a few more  plant images from our trip to Snowbird in the Wasatch Mountains, Utah.

Gardens in the Mountains – Wasatch Mountains

When hiking on the nearby trails doesn’t suffice anymore, we usually set out toward a mountain area to immerse in the richness of alpine landscapes. Two years ago at the end of July, we travelled to Snowbird, situated in the heart of scenic Wasatch Mountains, Utah. Although better known as a ski resort, during the summer, Snowbird offers an easy and comfortable access to some of the floristic gems of the Utah Rockies.

Wasatch Mountains stretch for nearly 200 miles from the Wellsville Mountains on the north, to the Mount Nebo on the south. Elevations range between 4,200 and 11,957 feet (at Mount Timpanogos). Along with jewel-like lakes there are pockets of lush green mountain meadows and areas of alpine tundra. Climate and microclimate differences produce a broad seasonal flowering spread. The basic rock types are made up principally of limestone and dolomite rocks. Soils of widely varying chemical composition are found throughout the area, thus providing a suitable environment for plants that require either acid soil or lime. These diverse habitat conditions make Wasatch Mountains a hotspot for plant endemism. One place where you can spend the whole day, just basking in the sun and admiring wildflowers is the Albion Basin. It is located at the top of glacially carved Little Cottonwood Canyon, above the ski resorts of Alta and Snowbird at over 9,500 feet. During the summer months of July-August there is a spectacular wildflower display in the high-elevation meadows with natural gardens of paintbrush, columbine, lupine, Jacob’s ladder, penstemons, and many more. This is where the Wasatch Wildflower Festival is held every year.

 A very interesting plant that I saw for the first time was Pedicularis groenlandicaElephant’s head (Orobanchaceae), which grows along streams and boggy mountain meadows, forming sometimes large colonies. It has fern-like leaves, mostly basal and dark green stems of about 1 foot high with flowers that look exactly like little magenta-pink elephant heads. Plants blooming for many weeks offer an image that is hard to forget. This beautiful plant is parasitic on the roots of the plants that grow in its vicinity, from which it extracts the nutrients it needs. Because of the parasitic life cycle, it would be probably very difficult to cultivate.

Another first was Aquilegia coeruleaColorado Blue columbine. It is a columbine with very long spurs and large flowers that can vary in colour from light blue to white (4 varieties in Flora of North America). Usually it grows close to wet stream areas in part-shade, but also can be found on rocky outcrops in full sun. The population we found had almost entirely white flowers. Taking the trail to Cecret Lake and then towards Germania Pass you’ll find a fabulous rocky area hosting Penstemon humilisLow penstemon (Plantaginaceae). It grows in many-stemmed clumps 4 to 12 ft. tall. The flowers are about 1.5 inches long, colored in every shade of blue from lavender to light sky blue and even magenta. Considering that there are more than 60 species of Penstemon in Utah, I have to mention at least a local endemism, the Wasatch PenstemonPenstemon cyananthus, which is common in the area, growing on dry, gravelly hillsides. Each plant produces several 2 to 3 ft. tall stems of magnificent blue flowers. You can definitely get your fix if you have agentian blue craving! We even found two very localized forms with white and pink flowers. Another day, on a hike to the Flagstaff Peak, we lost the trail that starts from the Alta Lodge, but were rewarded to find at the top of the ridge clumps of Clematis columbiana var. tenuiloba – Rock Clematis (Ranunculaceae). This is a rhizomatous clematis with aerial stems that are not viny, usually up to 10 cm tall and tufted. Leaves are typically 3-lobed and the flowers are deep pink to violet. It grows on cliffs and rocky summits, usually in open sites. It is a prized rock garden clematis, hard to find to buy, so this year I’m trying my own seeds (hope they’ll come true!).



Cypripedium arietinum

Lady’s slippers – What’s your size?

Orchids of Bruce Peninsula II

I was saying earlier that one could spot quite a few Cypripedium spp.- Lady’s slippers, at Singing Sands National Park in Bruce Peninsula. Tread lightly on the trails, watch carefully and maybe you’ll even meet the lady’s slippers fairy from the image below.

Cypripedium reginae – Showy lady’s slipper; it is usually found in fens and swamps and it’s easy to recognize after the bright pink slipper with a round opening. The pink blushing of the pouch can vary greatly in the populations, from deep pink to even, in rare cases, ‘albino’ individuals. As a complement to the flowers are the beautifully ribbed, wide leaves.

 Cypripedium arietinum – Ram’s head. Easily recognisable after the unusual shape of the slipper (lip), which also has reddish reticulations. It is flowering a bit earlier than C. reginae and parviflorum, so a visit in late May is advisable.

 Cypripedium parviflorum – Yellow lady’s slipper; it is an extremely variable species in regards to flower size and colours. Currently there are 3 varieties recognized in Flora of North America: var. pubescens, var. parviflorum and var. makasin. Personally, I can say that plants growing on drier sites have the slipper usually yellow and larger than those growing in wet habitats (most likely with reddish slipper).

I would strongly advise everyone with the desire and intention of growing orchids in their garden to try to see them first in their native habitat. High prices, of any orchids, are rightly justified by the difficulty to propagate them (mainly in vitro) and the length of time necessary to obtain a flowering size plant (5-7 years). There are many hybrids in cultivation today, which besides interesting flower colours, are said to be more adaptable and faster growing in garden conditions.


Polygala paucifolia - in the Bruce Peninsula, Ontario

A yummy treat – Polygala paucifolia

One of my goals is to concentrate on the propagation of a few N. American native plants that would be as prized in our garden as any Chinese or S. American novelties. The hype of using native plants in our gardens and landscapes it always cut short by their difficulty to propagate (and by the lack of available seeds collections, of course). Whatever doesn’t fit into the profile of mass-production has been abandoned or perhaps not even tried in cultivation.

Besides serving an ornamental function, expanding into cultivation a few of the hard to find and/or propagate N. American species, would serve also a conservation purpose by maintaining and enriching the genetic material/ biodiversity through sexual propagation.Conservation through cultivation, (aka propagation) has already proved its importance in a few unfortunate cases of species extinct in the wild but saved, at least temporarily, in gardens sanctuaries.

 “No, no! The adventures first, explanations take such a dreadful time!” – Lewis Carroll: Alice’s Adventures in Wonderland

OK. Last year we were able to finally collect a few seeds of Polygala paucifolia –Gaywings or Fringed polygala This is a low growing plant found in dry to moist woods, in part shade. It flowers in May-June and the pink-purple flowers are quite unusual – they have 3 short and 2 long wing-like sepals and 3 joined petals with a frilly crest at the tip. Fruit is a capsule.  The seeds present an appendage – elaiosome, which is associated with ant dispersal – now you see where I’m going? A bit too late and the seeds are gone. The appendage contains lipids, proteins and starch, which serve as a reward for the ants. They drag the seeds to their nests to feed their youngs on elaiosomes and thus provide the service of dispersal. I bet they are very yummy!


 The germination ecology for species from Polygalaceae has not been investigated in detail. I found a study claiming that for P. paucifolia, 4 months of dry storage results in an increase in germination. Other Polygala species are known to require pre-treatments for germination. Anyway, I don’t have that many seeds, so for this year I’ll try two variants: dry storage and moist-cold stratification until sowing in the spring.

 We shall see…the seed adventure continues!

 Note:  Many spring flowers from the temperate climate rely on ants to disperse their seed  (myrmecochory – I wouldn’t try pronouncing this); from the very well known: Trillium, Hepatica, Corydalis, Dicentra…



Aralia hispida fruits

Bristly Sarsaparilla

While gazing to the rocky shores of the Georgian Bay in Killarney, one plant kept drawing my attention (and camera) – the bristly sarsaparilla: Aralia hispida. Growing in any small crack of the big granite boulders, with shiny leaves and blackish fruits proudly swinging in the wind, it made me think, again, how many wonderful, garden-worthy, but underutilized native plants are around.

Drought resistant, growing in full sun in rocky, poor substrates, this Aralia could be a prized plant for any garden. The leaves are twice pinnately-divided, and the stem base is covered by bristly hairs and becomes woody persisting through the winter. White-cream flowers appear in June-July in round umbels on stalks that diverge at the end of the stems; they are followed by purplish black fruits resembling a bit the elder fruits (hence the other popular name: dwarf elder). The inflorescences stalks become red, making a nice contrast with the black fruits towards the fall. But enough talk, the pictures are always more convincing…


Not to be confounded with Sarsaparilla – the common name used for various species of Smilax (greenbriers), more particularly for Smilax regelii.
