Chelidonium majus: foliage and flowers
Maianthemum stellatum: foliage and flowers
Here is a slightly blurry attempt to get a closer look at the flowers (click photo to enlarge). They are quite similar to those of its little cousin, wild lily-of-the-valley (M. canadense).
I photographed this plant in High Park, a bit south of the Black Oak Café on the right side of the path.

Waldsteinia fragaroides: flowers
When I was growing up in eastern Ontario, barren strawberries carpeted the forest floor; i.e. they can make a good groundcover for shade in the right conditions. I bought this plant at the North American Native Plant Society plant sale last weekend.

Caltha palustris: flowers
It's been decades since I've seen marsh marigold in real life. I was thrilled to see these gorgeous flowers at Wilket Creek Park.

Podophyllum peltatum: foliage
I photographed these plants in Wilket Creek Park.

Dicentra cucullaria: foliage and flowers
I had never seen this plant in real life, and was very pleased to discover it in a neighbour's garden.
Alliaria petiolata: foliage
Garlic mustard was originally brought to Canada from Europe as a food plant. Unfortunately, it has flourished too well. Garlic mustard is not edible to Canadian wildlife, it emerges early in the spring before many native plants, it produces large numbers of seeds, and it harms mycorrhizal fungi that native plants need to grow properly. These factors give it an advantage over native plants, with the result that it can invade forests and outcompete them. There are areas of the forest in High Park that are completely overrun with garlic mustard, at the expense of native plants. Garlic mustard is invading the forest around the Ontario Science Centre as well, endangering their beautiful white trilliums. Because Canadian wildlife won't eat garlic mustard, replacing native plants with garlic mustard means less food for wild animals and therefore a loss of animal as well as plant biodiversity.
For these and other reasons it is important for Toronto gardeners to be able to recognize garlic mustard and remove it. In the first year, garlic mustard forms a low rosette of heart- or kidney-shaped leaves with a jagged edge. The leaves have a distinctive garlicky smell when crushed. In the second year, the plant produces a stem 30-60 cm tall with clusters of small, white, four-petalled flowers. The flowers are followed by skinny upright seed pods, but please don't let it get to that stage if you can help it. After setting seed, the plant dies, which is good news. (There are some good photos of garlic mustard leaves, flowers, and seed pods on this page by the Plant Conservation Alliance Alien Plant Working Group.)
To control garlic mustard, remove the entire plant in the first year, or remove at the very least the flowers in the second year (in erosion-prone sites you may want to leave the roots of second year plants in place, but cut the plants off close to the ground, otherwise more flowers can form in the leaf axils). Don't leave the flowers or unripe seedpods lying around as even if cut off from the root they can still ripen and produce viable seed. You can eat the plants if you like; here's a recipe for garlic mustard pesto (I haven't tried it myself yet).
Garlic mustard seed in the soil remains viable for years, so eradicating it is a long-term project. So let's make it a May tradition to enjoy a walk outside eradicating garlic mustard!
Liatris spicata (I think): new growth
I wasn't sure if my liatris was going to return this year, as it was weeded out by someone else, but it looks like enough bits were left behind to come back! I'm looking forward to its colourful blooms.

Acer rubrum: small sapling with new foliage
Ambrosia artemisiifolia: foliage
Last year when these pretty leaves started emerging in the spring, I was sure they were something "good". Imagine my disappointment when I realised they were in fact ragweed. Ragweed's flowers are tiny and green; they don't need to be showy to attract insects because they are wind-pollinated. I don't know if I'm allergic to ragweed myself (I'm stuffed up all year round due to my fibromyalgia), but a friend down the street suffered from ragweed allergies, and ragweed pollen can travel hundreds of miles on the wind.
Even though ragweed is a native plant, I think those of us in populated areas should pull it out of consideration for all the people sickened by ragweed pollen. The Ontario government has designated ragweed as a noxious weed.

Tussilago farfara: flowers
The Invasive Exotic Species Ranking for Southern Ontario rates coltsfoot as Category 4 ("Exotic species that do not pose a serious threat to natural areas unless they are competing directly with more desirable vegetation.")
Coltsfoot has traditionally been used medicinally, but is toxic in large doses. Also, European Journal of Pediatrics reported a case of an infant who developed hepatic veno-occlusive disease after regular consumption of what his parents thought was coltsfoot, but was actually Adenostyles alliariae, which shows the importance of being cautious about gathering and self-treating with wild plants.
I photographed these plants at the University of Toronto downtown campus on St. George north of College.

Tulipa turkestanica: flowers
This pretty clump is blooming in a talented neighbour's garden.

Geum triflorum: flowers
Hyacinthus orientalis in bloom
Well, most of the budding hyacinths I posted a few weeks ago were trampled, alas. This is the least mangled of the plants.
Eranthis hyemalis: unripe seed pods
Here are the developing seedpods. To me, this plant is beautiful at every stage of development.

Garden bloggers' Bloom Day April 2009
Although I'm supposedly in the same zone as Carol, spring is coming more slowly here in Toronto though unlike last month, I do have a few blooms to post today.
The Siberian squill (Scilla siberica), which the landlords' kids and I rescued from a garden down the street last year, are in their glory now.
Unfortunately, I found out long after the kids and I rescued them that Siberian squill is an invasive species in southern Ontario according to Invasive Exotic Species Ranking for Southern Ontario. I need to learn more about how the things spread; hopefully I can control them, since the landlords' eldest will be very unhappy if I rip out his squill.
Only one of my reticulated irises (Iris reticulata 'Cantab') is still in bloom. This picture came out badly but I didn't have time to take another because I had to catch a train—I'm posting this from my mom's apartment in eastern Ontario. Fortunately I got a prettier picture a couple of weeks ago.
This early stardrift, still in bud, (Puschkinia libanotica) is another rescue from the garden down the street. (Here's a photo of the gorgeous masses of early stardrift in that garden before the new owner attempted to replace it with sod. I say "attempted" because a number of puschkinia have popped up through the lawn this year despite his efforts.)
All of the flowers out today are blue, but we did have some bright yellow winter aconite (Eranthis hyemalis, see photo) which bloomed at the end of March, managing to avoid both the March and April Bloom Days. There are also hyacinths and tulips in bud, and lots of growth on the daffodills, columbines, and beebalm. Lots to look forward to!
I couldn't resist including the Easter decorations the landlords' kids put up, which add lots of gay colour even though they aren't technically blooms. I think that decorating Easter trees is a Czech tradition.

Intriguing mystery bulb
Dicentra spectabilis: emerging foliage
I just discovered this lovely bleeding heart foliage emerging this week—it was hidden under some windblown trash which is all too prevalent in this neighbourhood for some reason (drives me nuts). I just bought this plant last spring; it's good to see that it survived the winter.
Here are lists of all the plants mentioned in this blog.
