Why on Earth are flowers beautiful?

If you watch science documentaries like Nova or The Nature of Things, you might get the feeling that what’s most exciting about science is all the questions scientists have answers to – all the things we’ve learned about how our universe ticks.  (It’s built right into the title of The Nature of Things.)  But what I love most about science, and especially biology, is how easy it is to ask a question that we don’t have the answer to.  Why are there so many species of beetles*, but so few of snakeflies?  Why does life use a basic set of 20 amino acids, not 18 or 26?  And one that has me completely stumped: why on Earth are flowers beautiful?

“Why are flowers beautiful” might sound like a trivial question, but I don’t think it is.  Continue reading

My latest paper is a garden

As a scientist, I’m really a writer, in the important sense that my research doesn’t matter until it’s published.  As a result, I’ve come to celebrate completion of a project not when I collect the last sample, enter the last bit of data, or conduct the last analysis.  Instead, I celebrate completion when the paper is published and available for the world to see*.

But my most recent paper isn’t a paper; it’s a garden.  And just a couple of weeks ago we had its official opening, and I’m counting that as “my” garden’s publication date.  I’ve just published my garden!

About that garden: Continue reading

Plants in ecological webs

A visit to any Botanic Garden surely means attention paid to plants – that’s what “Botanic” means, after all.  When you visit our Fredericton Botanic Garden, for example, your attention will probably first be drawn to our flowerbeds and forests; to the primulas in the Hal Hinds Garden and the daylilies in our newly expanded Daylily Bed; to the reeds by our ponds and the ferns along our Woodland Fern Trail.  All these beautiful plants are worth your time – but we hope you’ll look beyond them, too.  That’s because each of our plants is also part of a larger ecological web.

Entrepreneurship in Victorian botany: did you know that was a thing?

Last week, I did a little ranting about what I consider the fetishization of entrepreneurship in our society.  In the Replies, a couple of readers pushed back, pointing out ways in which entrepreneurship serves economic and societal purposes.  I’m glad to have the pushback (especially because so far, nobody has gotten incoherently angry about the post).  I’m even going to add a little pushback myself*.  Did you know that entrepreneurship underwrote one of the most amazing botanical expeditions in history?

Three witches in the woods

Happy Hallowe’en!

Tonight, you’ll no doubt see neighbourhood children traipsing door-to-door in costume, shrieking and laughing along the way.  You’ll see superheroes and scarecrows, pirates and police officers, wizards and witches. Some costumes go in and out of fashion; but there are witches every year.

There are witches in the woods, too. Continue reading

The botany of henna

Henna-based body art has thousands of years of history in India, Africa, and the Middle East, and it’s an increasingly common sight in the Western world too.  The intricate designs are beautiful, and many traditional designs are packed with symbolism and story.  But the henna itself has a story, too – a botanical one.  For those of us who love plants, history, and naming, there’s a lot to like about henna.

Spring, light, and strategy on the forest floor

Spring is upon us, and it’s a great time for a walk in the woods that are part of our Botanic Garden.  In a deciduous forest, spring finds the forest floor sprinkled with green and with flashes of colour from blooming “spring ephemerals”.  The trout lily pictured above is an example, as are wood anemone, trillium, bloodroot, and a bunch of my other favourites.  But if you walk the same trail in July, you’d be hard pressed to know some of these spring bloomers were ever there – not only is their flowering finished, but their green leaves and stems have withered and gone.  Why?
