Provincial Post - Manitoba Prairie Crocus


Last winter I began a series of posts called Provincial Posts where I showcase one of Canada's provincial flowers. As it is now officially winter (I have snow, about 4 inches of fluffy real snow) I thought to reprise these posts.

The Prairie crocus or Pulsatilla patens was adopted as the provincial flower of Manitoba  in 1906. The province decided to do something creative and asked school children to vote on their choice of flower to represent the province.

Also known as Anemone patens, the Prairie Crocus flower blooms in early spring before the snow melts on the prairie. Beautiful mauve to purple blossoms appear first and reach a height of 6 inches. The plant blooms for about two weeks and prefers to open its blossoms when the sun is out. When the leaves emerge this native perennial grows to one and a half feet tall.  Both the sepals and especially the stems of the crocus are covered in long silky hairs that shine brilliantly in the sun. The basal leaves that emerge as the flowers are failing are in three's and are finely dissected. The undersides of the leaves are also covered in silky hairs.

Bees are the primary pollinators of the Prairie crocus. Halictid bees are known to pollinate the crocus (Agapostemon texanus texanus and Halictus rubicunda). The seeds are produced by June and in ideal moist conditions can germinate right away. Otherwise the seeds go dormant and wait until next spring to germinate. By mid July in Manitoba the crocus begins to die back, just as most other perennials are coming into their prime.

Prairie crocus is in the family Ranunculaceae, native to Europe, Russia, Mongolia, China, Canada and the United States. Plants in Eurasia tend to have more variety in colour than our native crocus. Common names include Eastern pasqueflower, prairie smoke, prairie crocus, and cutleaf anemone.

A Gift in Tones of Pink


I received a gift the other day, a pot of ornamental cabbage.


I have seen ornamental cabbage in pictures but never had any myself. Now I do. 



My generous gift will live for a few more months, probably dependent on the weather.


This plant is prettier than I ever thought - if I had considered that at all.


Now it adorns my front stairs and brightens my day.

What do You do when you run out of photo storage ?

Sigh,
it is hard not understanding how some things work.

I have run out of storage for my photos and am trying to figure out what to do next. Yes, google says I can pay for extra storage, but it also says I can get additional free storage of 5 GB on google drive. So I install google drive, save my photos in a folder within and do what I believe I need to do to get these photos in my post. But of course it does not work.

My question to you is, what do you do to increase your storage for photos and video?

Climate Change and Assisted Migration

As gardeners we are, knowingly or not, involved in an act called Assisted Migration. It is definitely a 21st century term and it is defined as,  “Movement of species beyond their historical range either to prevent extinction due to climate change … or facilitate their adaptation to future or projected climate change”, according to Nicole Klenk , a social scientist at the University of Waterloo.  While gardeners of all types from all ages have always coveted what their neighbours had and we did not, we have transported plant and animal species from one country to another, over land and sea, in order to revel in and admire a new discovery, and to own one for ourselves. Today however we are doing this for different reasons, namely the continued survival of plant and animal species, and it is called Assisted Migration. 

Scientists have been studying climate change for a couple of decades and are now seeing ties to the loss of animal and plant habitats. As areas of the earth are warming or cooling we are finding that some species are finding it difficult to adapt to the changes and are therefore at risk. There has been a slow movement by groups and individuals alike to protect the species we love by moving them to locations where they hope they will continue to survive for years to come. 
 
There are two cases of assisted migration in the news which involve moving a species far from its local habitat. The first is a conifer in Florida, Torreya taxifolia, with a shrinking range in the Florida panhandle. The group Citizens of Torreya Taxifolia Guardians are planting seeds of Torreya taxifolia from private stock or garden centres outside of its northern range in North Carolina.

A second example headed by Richard Branson of the Virgin Group was to move Madagascar lemurs onto an island that he owns. The plan was to move animals from zoos or private organizations with the intent to protect the species. Conservation scientists criticised him for potentially creating risks to other species on the island. These examples are of citizens making choices on their own (which may be ill informed) and without any government and academic oversight. The concern is that these types of assisted migration may cause more harm by changing native ecosystems. However these actions are also presently perfectly legal.

The philosophy of what we are doing concerns Anthony Ricciardi an Associate professor and invasive species biologist at McGill University. He is not opposed to assisted migration or what he calls assisted range expansion, but the intentional moving of species, such as moving animals to another island. We have a long history of moving plants and animals around the world and have caused some degree of ecological damage by degrading habitat, introducing diseases and pests, and the extinction of native species. Do these long distance introductions such as moving certain plants or animals outweigh the risks of ecological damage? Mr. Ricciardi claims there are no reliable ways to forecast the risks of a species introduction. There are risks with assisted migration such as, creating new invasive species, the effect on the local ecosystem, and the interaction with local species.  He says we need to deal with the root cause rather than moving species around.

The Emerald Ash Borer is quite destructive in parts of Canada and the US. Brought in on packing crates from China.

British Columbia is presently a world leader in a large scale experiment of assisted migration. They are moving 15 tree species (of commercial value) to the northern edge of their range with the intent to study their adaptation to future climate change. They are hoping to develop a seed bank that will be successful in providing trees adapted to a more northern range. To determine success we must wait 15 to 20 years and expect that up to 50% of those seedlings will not survive. 

Professor Sally Aitken in Vancouver, a Forest Geneticist at University of British Columbia, is working on an experiment to save the white bark pine. The white bark pine is listed as threatened in Canada and is in rapid decline in western Canada and USA due to white pine blister rust, the mountain pine beetle, and loss of habitat. This pine has many positive ecological ties to the ecosystem that scientists consider it worth trying to save. As part of a controlled experiment they are moving it by seed within its existing range, to north of its range and in places where it is not expected to survive in BC. The only risk is increased invasion of the white pine, but since it is a slow growing and moving tree the risk is very small, as well, the ecosystem the pines are planted in is already part of its regional flora.
How can we mitigate the impact of carbon emissions on ecosystems? While this is a controversial and difficult problem to solve, we are attempting different ways of dealing with it by assisted migration taken in tiny steps as with the tree studies, and in large steps with the removal of species to areas outside their natural range. Some will argue we need to be working on the root cause. Who is right?

Guell Park, Barcelona

You would have thought that the gardener in me wanted to ensure a visit to the botanical gardens in Barcelona Spain. It turns out a week is not enough time to do everything on the list and the gardens were missed. 
Primary on the list was to visit all the Antoni Gaudi buildings that we could. Gaudi is called an architect but truly he is a visionary. His career spanned the late 1800's into the early 20th century of the Modernist Period or Art Nouveau period. He had luck on his side as he found his patron and client in Eusebi Guell early in his career. The homes and other buildings such as the Basilica Sagrada Familia could not be built today as they involve immense skilled labor not to mention high quality and expensive woods, stones, glass etc. For a gardener or naturalist, however, Gaudi's works are a joy to behold. Nature is part of his design whether it is the swirl of a shell or an obvious creature like the salamander.
Let's have a stroll through the gardens of Guell Park.


Coming in from the hills on the west




The main building in the park is by the front entrance. It is a complicated structure that serves many purposes. First you are greeted by a large staircase with the dragon that is a fountain which flows to a pool below him.



Up the stairs and you are in a covered 'hypostyle' hall with columns. The square above is a large area for the public to get a great view of the city. Notice the mosaics on the winding bench that serves as the wall to the square. The square is actually a water collecting point that sends rainwater through the columns into a cistern below the hypostyle which is used for watering the gardens. Ingenious.

This is the ceiling of the hypostyle. Natural organic forms in abundance


We move on to another area. This a courtyard with columns of quite a different sort. Gone are the fluted columns and medallions of colour that represent stars ? shells ? and we are surrounded by rock and stone.



Close up of the planters on top. They are filled with succulents like agave and yucca.

The inner courtyard below is made to resemble trees. Each column is made of stone and each one is individual from the others. Walking paths are above the courtyard and provide the shrubbery that is the trees canopies.



In the photo below, the columns create a wonderful covered portico and are of course skillfully arched.

The next photos are of some of the flowering plants we saw. Unfortunately I still don't know what they are - I had intended to try and research Spain's flora but never did. These were plants that we saw in many areas in this park and others.


The blue is ipomea or morning glory.



Agave's in the dry soil


These were in planters throughout the city as well


Bougainvillea 1


Bougainvillea 2


Hibiscus


     A soft pale blue. Looks phlox - like


This is a stunning flower


Very pretty too. Notice that a lot of the foliage is greyish which tells you how little water they get.


Flowering  agave. Unfortunately too high to see the flower. I am standing at the same level as the plant in earth.

Barcelona is a beautiful city in Spain. We loved every minute and hope to return one day as we do for Amsterdam. Next time I will buy a book on the Spanish flora so I know what I am looking at.

de Hortus Botanical Gardens, Amsterdam

Back in September hubby and I enjoyed a wonderful week in the city of Amsterdam, Holland. The city is probably best known for its canals, bike riding citizens and it's views on marijuana.
We spent half a day at the small but wonderful Hortus botanical garden just on the edge of the city. Created in 1638 it is one of the oldest botanical gardens in the world. It houses a Palm House, a Three-Climate Greenhouse, a small butterfly with cacti greenhouse, a wonderful organic restaurant under the trees at the Orangery, plus some lovely gardens. They claim that the Hortus houses more than 4,000 different species of plants, which is about 2% of all plant species growing on Earth. The Hortus specializes in Palms, Cyads, South African plants, carnivorous plants and are very proud of their herb garden the Hortus Medicus. The Hortus Medicus is a medicinal herb garden which was of vital importance in its time as it provided herbs to doctors and pharmacists of the 17th century.

Upon entering the gardens we first came across a large pond with waterlilies. There was even a beautiful bud emerging.






Here I am in the Semicircle. The Semicircle has an interesting idea behind it. I give you their words to explain; " The Semicircle portrays plant systematics: species that are closely related can be found growing near each other, while those that have little in common are grown far apart. This is the first and only systematic garden in The Netherlands in which the plants are categorized according to 'molecular systematics'. This kind of systematics is based on the similarities between genetic material."

And if you really want all the details:






The tree area had many many gorgeous trees, especially conifers. I give you one gnarly beauty and the Wollemi Pine. This pine died as you can see but they did have another in a greenhouse that looked healthy.






Dead Wollemi PIne



The Wollemi Pine is an ancient tree (290-200 million years ago) thought to be extinct but found in Australia in 1994. World wide conservation of this tree began in 2005. The Royal Botanical Gardens in Hamilton also houses a Wollemi Pine. It took many years for Australia to grow new seedlings in order to distribute them across the globe to other botanical gardens.

Below are two photos of the Palm House. The cool thing about this conservatory (besides the plants) was the stair and catwalk that allowed you to view the plants from a height.




From above





I did manage to find the hardy carnivorous plants in a small bog outside the Palm house, the rest were in the South Africa conservatory.


Sarracenia

We moved into the Three Climate house, which very cool and very hot. These photos are primarily of the jungle in the hottest of the houses.






Notice the pink bud to my right. No idea what it is.

Pink bud
Bottlebrush ?





Very thorny tree. I never saw the top of it.


 
Tillandsia mallemontii

 We left the humid jungle behind with sweat was dripping off my forehead - not something a girl from Canada relishes. The South African house was dry and cool and a relief after that.


It was here we found the second Wollemi Pine. Doesn't it look nice? and alive? The first one had been grown outdoors and was killed by a frost. 


I don't know what this is but I love it. Like a yew with fushia-like flowers. Nice.

Last, a few photos from their butterfly house. The house also held cacti but I don't remember them and I certainly did not get any pictures of them. I was concentrating on capturing the few types of butterflies they had, but the darn things kept moving around.

Poor old tattered flutterby


Must be a lot of fighting going on. More torn wings.





That is all of my visit to the Hortus Botanicus in Amsterdam. It would be nice to visit again in late spring early summer to see more of the flowers. We did have a lovely lunch out doors by the Orangery. Organic salads with really interesting and flavourful flourishes. They also have a very nice gift shop too.
