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

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

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

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

Edible Cat-tail vs. Toxic Iris
PEI has so many wild foods on offer in May: fiddleheads and nettle greens, burdock and primrose roots, morel mushrooms and pheasant’s backs, and so much more! Cat-tails (Typha latifolia) are versatile and easy to use, but it’s good to know how to tell them from a toxic plant of the same wet habitats: Blue-flag Iris (Iris versicolor). Cat-tails and Iris aren’t hard to tell apart in summer and fall, but it can be easy to confuse them where they grow side-by-side in spring (ma

Eelgrass
There’s one PEI plant that most people are very familiar with, but few have seen growing in its natural habitat: Eelgrass (Zostera marina). This is how most of us know Eelgrass: washed up along the shore. Eelgrass actually grows in extensive beds offshore as well as in our bays and estuaries, and – despite what you may think – it’s a true flowering plant and not a seaweed. Eelgrass has roots, stems, leaves, flowers, and vascular tissue (structures that move water and nutr

Edible Fir vs. Toxic Yew
It’s almost conifer-tip season, that time of year when we can enjoy the tasty, Vitamin-C-rich, new growth of our needle-leaved trees. While all of our conifer trees are edible, PEI does have one poisonous, native conifer shrub. Can you tell which of the needles in the photo are tasty and which are toxic? When it comes to conifer tips, White Spruce (Picea glauca) is the species most commonly used in the kitchen, as well as my personal favourite (you can find more details in

Geese and Mussels
The sound of Canada Geese is one of my favourite signs of spring – “goose music”, as Aldo Leopold called it. Their northerly migration is also marked by the return of feeding signs in PEI’s bays and estuaries, and some related behaviour that may surprise you! You may think of Canada Geese as herbivores that feed on aquatic vegetation and grasses in spring and summer, and the remnants of agricultural crops in fall. But, like many herbivores, Canada Geese are not strict veget

Marsh Marigold
As a botanist, I confess to teasing birders from time to time: groups of people flocking to the same spot to see an unusual species – really? But then spring rolls around and I eat my words as I make my annual pilgrimage to Miscouche to see Marsh Marigolds (Caltha palustris). Marsh Marigolds are neither unusual nor rare on PEI (and they aren’t Marigolds). This member of the Buttercup Family (Ranunculaceae) is found in wet, mucky soil, and so is more common in Prince and Kin

Baby Wildlife
Spring is a time of renewal, including for PEI’s wildlife. Early breeders such as Coyotes, Foxes, and Ravens have their young now, and others such as Snowshoe Hares, Striped Skunks, and Red Squirrels will follow soon. Our migratory birds are also returning and will make starting a family job one. This is an important time of year for wildlife, but it’s also the time of year when well-meaning people can do the most harm. Seeing young animals in spring and summer is normal an

Red Maple Flowers
It’s that time of year when many people are anticipating the first flowers of spring, without realizing that some are already here! We’ve looked at two of my favorite precocious plants – Willow and Beaked Hazelnut – but I also have a soft spot for Red Maple ( Acer rubrum ), flowering now. When we think of flowering trees, it’s often Apples, Cherries, and Serviceberries that come to mind. These showy species follow the usual order of things: leaf out first, then flower. But

Hazelnut Flowers
Some of PEI’s early spring wildflowers are showy, in-your-face sorts. Others are tiny, delicate, and go unnoticed to all except to those specifically looking for them. Today’s plant is in the latter category, and one of my favourites: Beaked Hazelnut ( Corylus cornuta ), flowering now. Hazelnut is a common, native understorey shrub found in mixed forests and along streams and trails across the Island. It stands out in the landscape this time of year, with finger-like male c

Black Knot Fungus
This is a great time of year to spot a PEI fungust that's best known as a disease of Cherry trees: Black Knot ( Apiosporina morbosa ). Black Knot fungus forms distinctive, black galls on stems and branches of our native Pin Cherry and Chokecherry, as well as ornamental Cherries and Plums. While it’s unattractive, reduces fruit production, and may kill the infected branch, Black Knot doesn’t usually kill the entire tree unless the infection is very severe. Within those black
