Ox-eye Daisy
This week, we’re looking at a couple of edible non-native wildflowers that are in season right now. On Monday, it was Tufted Vetch; today we have Ox-eye Daisy (Leucanthemum vulgare). Most people are familiar with Ox-eye Daisy’s distinctive white petals (ray flowers) surrounding the golden-yellow centre (disk flowers). This cheerful-looking plant can be found across the Island, pushing up through cracks in sidewalks, growing among the stone landscaping of highway dividers, l

Tufted Vetch
This week, we’re looking at a couple of edible non-native wildflowers that are in season right now. First up: Tufted Vetch (Vicia cracca). Tufted Vetch is a member of the Pea Family (Fabaceae) with clusters of purple flowers at the ends of stalks that arise from the leaf axils. (If you look closely at a flower cluster in person, you’ll see that each tiny blossom resembles a little bird with its beak against the flower stalk). Vetch leaves are like narrow versions of garden

Common Comfrey
There are some PEI plants that, when I find them, suggest there was once a homestead nearby. Wild Apples and abandoned Lilacs are two examples, but so too is Common Comfrey (Symphytum officinale). Comfrey is native to Europe and parts of Asia and was brought to North America as a medicinal and ornamental plant in the 1600s. This plant’s name attests to its long history of medicinal use: Symphytum is from ancient Greek words meaning ‘unite’ and ‘a plant’, while officinale wa

Red-mouth Bolete
I love meeting a new-to-me mushroom, and so was quite happy when I found these among my favourite patch of King Boletes (aka Porcini) last week. Meet the aptly named Red-mouth Bolete (Neoboletus subvelutipes). Followers of this page will know that mushrooms with spongy pores rather than gills, folds, or teeth under the cap are boletes. (Not all boletes have spongy pores, but mushrooms that do are boletes. And if you haven’t been following this page, you can get caught up on

Starry False Solomon's Seal
When we think about wildflowers, coastal areas often get overlooked in favour of fields, forests, and roadsides. But that means missing some of PEI’s loveliest native plants, including Starry False Solomon’s Seal (Maianthemum stellatum). Starry False Solomon’s Seal is a relative of Wild Lily-of-the-Valley, which I introduced you to earlier this spring. If you guessed these plants are members of the Lily Family (Liliaceae), you’d be sensible, but wrong! The genus Maianthemum

Alternate-leaved Dogwood
It’s great to see landscaping with native plants becoming mainstream. Many nurseries now carry at least some native species and seed mixes, while PEI’s Rural Beautification Society has added a Native Planting & Biodiversity category to its popular annual competition. The Island has many common, native plants that make beautiful additions to backyard gardens. One example: Alternate-leaved Dogwood (Cornus alternifolia). PEI has four native Dogwoods, which are all easy to spot

Is this edible?
This year’s damp weather may not be popular with everyone, but it has been great for mushrooms! The abundance of fruiting fungi has brought out a crop of social media posts asking about edibility. Here are some tips to help you ask the right questions and get reliable answers! I love encouraging people to try wild plants and fungi, but I cringe every time someone asks “is this edible?” That should never be your first question; instead, start with “what is this, and how can I

Chokecherry Flower Galls
Welcome back to Ask a Naturalist, your own personal Google for information on all things natural on PEI. I’ve been receiving photos of deformed Chokecherry (Prunus virginiana) flowers from around the Maritimes, including this one from Tara Matheson here on PEI. The cause is a fungus, Taphrina confusa. Let’s take a look! Normal Chokecherry flowers have five white petals and grow in finger-like groups, called ‘racemes’ (inset photo). Once pollinated, each flower will form an

English Hawthorne
If you’ve been travelling in central PEI lately, you’ve likely noticed a showy roadside tree with dense clusters of white flowers along the topsides of its branches – gardeners may be reminded of a giant version of the popular Bridal Wreath Spirea. This is English Hawthorne (Crataegus monogyna) and it’s having a banner year! PEI has several native species of Hawthornes that hybridize readily, making them notoriously hard to tell apart. However, our non-native English Hawtho

Melanistic Red Squirrels
Wildlife doesn’t always follow the rules, and despite their name, Red Squirrels are sometimes black. PEI has a higher-than-average number of black-furred Red Squirrels (such as this one photographed by Dave Campbell), so let’s take a look at this phenomenon! In mammals, skin and hair colour are determined by how much and what type of melanin is produced. Genetics controls melanin production, and most individuals within a species have similar colours: for example, Skunks are

Common Lilac
Some PEI plants are inextricably linked with people – not only in how the species arrived here, but also in their ongoing social and cultural value. I can think of no better example than the Common Lilac (Syringa vulgaris). Lilacs are not native to North America but were among the earliest flowers brought by European settlers. Considering the harsh conditions and limited space on ships crossing the North Atlantic in the 17th century – not to mention the utilitarian worldvie

Tartarian Honeysuckle
Public awareness of invasive species is high now, but that hasn’t always been the case. In the 1800s, if a foreign plant was edible, medicinal, or pretty, it was brought to North America without much thought. As a result, we are now dealing with dozens of problematic species, including invasive Honeysuckles. Tartarian Honeysuckle (Lonicera tartarica) was introduced to North America from Asia in the 1840s as an ornamental garden shrub. The same traits that make it attractive

Virginia Ctenucha
Welcome to Insect Appreciation Days, celebrated from June 8 – 13th annually, thanks to the Entomological Society of Canada. And what better insect to profile than PEI’s most commonly-reported moth, the Virginia Ctenucha (Ctenucha virginica)! First, what’s up with that name? Ctenucha (ten-OOO-sha) comes from a Greek word for ‘comb’, and refers to the feathery, comb-like antennae of the male moths. (The individual shown here is a female, with more wiry, less feathery antennae

Rhodora
Right now, wildflowers are doing an amazing job of brightening up PEI’s spring landscape. Even bogs – habitats that go unnoticed most of the year – are putting on glorious displays of colourful Rhodora (Rhododendron canadense). Islanders are lucky enough to live in one of the few places in the world where we can enjoy Rhodora’s amazing spring show. While many of PEI’s native plants are also common in central and western Canada, or extend down the Atlantic coast of the US, R

Ruby-throated Hummingbirds
With their tiny size, fearless personalities, and amazing agility, Hummingbirds capture our imaginations in a way few other birds can. PEI has only one species – the Ruby-throated Hummingbird – and their time with us is as short as an Island summer: from roughly Mother’s Day to Labour Day. Hummingbirds are creatures of extremes. They’re our smallest birds by far, weighing just a few grams (or about as much as a Canadian nickel); it would take more than 1,000 Ruby-throats to

Wild Apple
I love flowering tree season on PEI. Right now, roadsides and hedgerows are alive with blossoms of Chokecherry, Pin Cherry, Hawthorne, Serviceberry and soon, the showiest of all: wild Apple. Unlike many of our other familiar fruit, Apples are not native to PEI. Strawberries, Raspberries, Blackberries, and wild Cherries have all been here for thousands of years, but Apples were brought by the earliest settlers in the 1700s. Given the limited and unpredictable nature of wild

Oil Beetles
Perhaps it’s because there are so few blue plants, animals, or fungi in nature that they seem to really catch our attention. That is definitely true of this beautiful Oil Beetle (aka Short-winged Blister Beetle, Meloe angusticollis), photographed in eastern PEI earlier this month by Carla McKie. Oil Beetles get their name from oily, orange droplets that ooze from their joints when the beetles are threatened. That substance is haemolymph (insect blood), and it also gives the

Entolomatoid Mushrooms
Late summer and fall may be peak mushroom seasons on PEI, but spring has fungi to find, too! While checking my go-to spots for Morels this week, I found lots of these Entolomatoid Mushrooms (Family Entolomataceae). I often ignore LBMs (little brown mushrooms) as being too hard to identify and above my skill level. However, as I gain experience in mushroom identification, I’ve started looking for clues that point to the Family. If you’ve attended any of my workshops, you’ll

June Bugs
They’re baaaack! Here in Central PEI, the first Hummingbird and the first June Bug arrived within a couple of days of each other last week. Most people look forward to seeing the tiny birds far more than they do the shiny insects, but what exactly are June Bugs anyway? Let’s take a look! “June Bug” is a general term used to refer to many different species in the Scarab Beetle Family (Scarabaeidae). The ones found most often on PEI are the native Phyllophaga anxia, although at

Wild Lily-of-the-Valley Leaves
One of the nicest treats of a PEI spring is harvesting your own fresh, local food after a winter of stored root vegetables and imported fare. Fiddleheads, dandelions, cat-tails, dock, watercress, and magnolia – along with pheasant back and morel mushrooms if you can find them – are all in season right now. But if you’re looking for something new, give Wild Lily-of-the-valley (Maianthemum canadense) a try. Followers of my blog may remember that I introduced you to this plant
