One of PEI’s most common woodland plants is often overlooked, occasionally misidentified, and fruiting now. Meet Sarsaparilla (pronounced ‘sass-parilla’, Aralia nudicaulis). Sarsaparilla is about 30 to 45 centimetres (a foot to 1.5 feet) tall and is divided into three branches, each with three to five leaflets (main photo). Those leaflets are often reddish when they first appear in spring, and they turn red again in fall. This, coupled with the old saying “leaves of three,

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

Today’s PEI plant is one that I’ve received many questions about, along with a request to do a post on it. So, meet Bittersweet Nightshade (Solanum dulcamera)! If these flowers remind you of tomato or potato blossoms, give yourself a gold star. Bittersweet Nightshade is in the same family (and the same genus) as those domestic crops, and is related to other familiar species including eggplant, peppers (both sweet and hot), gogi berries, and tobacco. Bittersweet Nightshade

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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
