Eyebright
Today’s fall flowering plant proves that you don’t need to be big to be showy: meet the small and beautiful Common Eyebright (Euphrasia nemorosa). Common Eyebright is native to Europe but was first recorded in Canada in 1792, and discovered in the US about 50 years later. Although this plant does have traditional medicinal uses, Eyebright’s arrival to this continent is thought to have been accidental rather than intentional. Today, Common Eyebright is found in grassy area

Witch Hazel
I love PEI’s fall colours. Not only the changing leaves and vibrant fungi, but also late-season flowering plants like Witch Hazel (Hamamelis virginiana). When people ask me about planting native species for pollinators, my thoughts always go immediately to very early and very late flowering plants. Any pollinator worth its salt can making a living from the Island’s landscape in peak summer, but resources are much scarcer in early spring and now, as our native bees, butterfl

Yellow Garden Spider
Fall is peak spider season on PEI, and the most commonly-reported of our nearly 200 different species is the lovely Yellow Garden Spider (Argiope aurantia). If you are among the 6% of the population that experiences arachnophobia – fear of spiders – you may not be happy with either today’s photo or my reference to just how many species the Island has. And, if that’s the case, you really won’t like me mentioning that one UK researcher estimated that there are as many as two mi

Destroying Angels
It’s Mushroom Monday, and this week we have one of PEI’s most notorious species. Despite its reputation, this mushroom is beautiful, ecologically important, and perfectly harmless if you don’t eat it. Meet a Destroying Angel (Amanita cf. amerivirosa). ‘Destroying Angel’ isn’t a single species, but the name applied to a group of all-white, very toxic mushrooms in the genus Amanita. Research has confirmed three separate species in our region so far, with A. amerivirosa being

White-margined Burrowing Bug
I love getting questions about the wild side of PEI and so was thrilled to get this photo from Megan Jones. She found this clump of bright red insects in some old straw near her barn and was curious about their identification and whether they could be invasive. These are the lovely – and native – nymphs of the White-margined Burrowing Bug (Sehirus cinctus). Let’s take a look! You could be forgiven for thinking these are Lady Beetles at first glance, given their similar red-

Stinky Squid
September on PEI doesn’t just mean shorter days, cooler weather, and back to school. It also means the return of Mushroom Mondays! Let’s kick the season off with a species that reminds us just how strange fungi can be: meet the Stinky Squid (Pseudocolus fusiformis). You could be forgiven for thinking this looks more like an alien than a mushroom. Stinky Squids start out as greyish eggs in the soil (inset photo) and, as they mature, develop three to four orange arms each cov

Joe Pye Weed
PEI’s late summer landscape belongs to the Aster Family: yellow Goldenrods, purple Asters, and – one of my personal favourites – pink Joe Pye Weed (Eutrochium maculatum). There are five Joe Pye species in North America, but Spotted Joe Pye Weed, shown here, is the only one we have on the Island. This plant can be found across the province, though I see it far more commonly in Prince County, where it grows in damp roadside ditches, meadows, and coastal areas. Spotted Joe Pye

Sea Stars
PEI has many interesting wild animals, but some of the most beautiful – and unusual – are Sea Stars, often called Starfish. The waters around PEI are home to at least five species, including the Common Sea Star (Asterias rubens) and Forbes Sea Star (A. forbesi). It’s not hard to see where these invertebrates get their name: ask any kindergartener to draw a star, and you’ll get something that resembles this five-pointed shape. While our most common Sea Stars do have five arm

Foxtail Barley
As fields of grain ripen across PEI, you may have noticed a similar, though smaller, plant growing along roadsides, coastlines, and trails. Although this plant hangs out in human habitats and looks like it may have escaped from farms or gardens, it’s actually a native species: meet Foxtail Barley (Hordeum jubatum). Like our agricultural grains, Foxtail Barley is a member of the grass family (Poaceae). It’s in the same genus as the commercial Barley you may enjoy in breakfas

Fireweed
PEI has wildflowers that are beautiful, edible, and ecologically important. Today we have an example that’s all three, and flowering now: Fireweed (Chamaenerion angustifolium)! Fireweed can be found across the Island, blooming in vacant urban lots, along rural roads and fields, and among forests impacted by 2022’s Hurricane Fiona. While it gets its name from an ability to recolonize land following wildfire, it doesn’t need fire to appear: any disturbance will do. Fireweed i

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

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

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

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

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

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
