Snapshots: Monday miscellany.

Or maybe “Mundane miscellany,” but I’ll leave that distinction up to you, LOL….

Tomato plants are happening under lights in the kitchen.  Since I took this pic, one set of true leaves has emerged on each plant.  I planted ‘Black Krim’ heirlooms (my first time trying them; my niece gave me seeds last year and I forgot about them until it was too late for me to do anything so I’m rectifying that situation this year) and ‘Candyland Red’ currant tomatoes.  This will be my third year planting the currant tomatoes, but I’ve never started them indoors.  Frost reduced potential yields previously so we’ll try it this way instead.

Smudge is super happy that I am at home to dispense chicken treats and deliver a cushiony lap whenever required.  I am trying to teach her how to read but so far she’s only demonstrated exemplary skills as a bookmark.

I’ve used the last shallot in the house…it’s an indicator to plant more this year and it’s also a nod to the fact that properly curing Allium crops can really extend their storage and diminish the risk of rot. Shameless plug alert: Janet Melrose and I write about how to properly cure onions and garlic in our upcoming book, The Prairie Gardener’s Go-To for Vegetables.  (Which you can preorder from Chapters-Indigo and Amazon via this link on our publisher’s website.  I may as well go whole hog on the plug, right?  Why do things halfway?).

Oh, and I’ve been eating pancakes for lunch.  Pretty much every day.  I don’t have a photo of this (neither the eating, nor the pancakes.  You’re probably grateful for the former, at least).  I use my Mum’s pretty much perfect pancake recipe (say that three times really quickly) but if you want to share yours in the comments, I would love to try it, as well! Tell me about your favourite pancake toppings, too!

Sheryl’s Mum’s Pretty Much Perfect Pancake Recipe (Mum, is it okay that I share this?) 😉 

1 1/2 cups flour

1 tablespoon sugar

3 teaspoons baking powder

1/2 teaspoon salt*

1 egg, beaten

1 3/4 cups milk

2 tablespoons vegetable oil or melted shortening

Mix all the dry ingredients, then add the liquid ones and combine.  Fry on a hot griddle. Yield: 8 sizeable pancakes, or several much smaller ones. (And in case you’re wondering, no, I’m not eating 8 sizeable pancakes at lunch – these guys keep over really nicely in the fridge for a few days and you can just reheat.  As well, the batch may be successfully halved, if that works better for you).

*Salt is optional.

 

Botany word of the week.

Aggregate fruit (as well as some bonus chatter about accessory and multiple fruits, pseudocarps, drupes, achenes, carpels, and…um…monkey bread?)

Occasionally (or possibly frequently, given the weird world we live in), things turn out to be different than advertised. Sort of like that purse I ordered off of the Internet. But I digress….

Case in point: raspberries and strawberries.  Are they actually berries?  You already know where I’m going with this!

What does it mean to be a berry?  Quite a few things, really, but one of them is that the fruit must develop from a flower possessing one ovary.  Strawberries and raspberries don’t fit the bill.  If you take a look at the fruit of a raspberry, you’ll notice that it is made up of a bunch of little nubs. You could pull each one apart, kind of like a loaf of monkey bread.  (Mmmm…how can you tell I haven’t eaten breakfast yet?).  Each one of these is called a drupe (drupelets), and they are produced from the multiple ovaries of a flower.  Each drupe contains a seed.  In the case of a strawberry, those little seed-like things on the outside are not actually seeds, although they do contain seeds. Those small bumps are called achenes.  Because these fruitlets were all joined together, they are called aggregrate fruits.  (Just to be confusing, not all multiple fruits – those with more than one ovary per flower – are aggregate.  Some don’t join together to form a single entity).

Raspberries

And, to add to the fun, strawberries are categorized as an accessory fruit (aka pseudocarp) in addition to an aggregate fruit. Some of that yummy fleshy stuff we eat is made up of tissue that originates near the carpel (modified leaves that surround the ovules) of the flower.

Okay, now that we’ve got that out of the way…I’m off to enjoy an aggregate fruit smoothie!  (Doesn’t have quite the same ring to it, does it?).  Do you grow raspberries and/or strawberries in your garden?  What ways do you use them in cooking and baking?

Pappose

A plant that bears a pappus (or more likely, pappi) is said to be pappose. With purpose.  And no porpoises.  (Please stop me before I go any further).

What’s a pappus, you say?

See this dandelion flower (actually a cluster of florets) that has gone to seed?  If you’ve ever held one in your hand and pulled a single seed away from the head, and then eyeballed it really closely…you’ll see that the fine, fuzzy white stuff on top (actually a modified calyx) sits above the thin brown seed like a skeletonized parachute.  The parachute calyx is a pappus, and although you can’t see all of them really well without a microscope, if you could count, you’d find that there are around 100 bristle-like filaments comprising each one. As dandelion seed is dispersed via wind, this pappus structure proves very useful, able to carry the seeds up to 100 kilometres (62 miles).

Dandelions aren’t the only plants that are pappose – you’ll find that most members of the daisy (Asteraceae) family are as well – but I’ve got one more fascinating dandelion pappus story to share before I sign off on this post. Get this: In 2018, researchers at the University of Edinburgh (using some cool gadgets such as a wind tunnel, lasers, high speed cameras, and x-ray microtomography) discovered the precise number of and the specific way the filaments in each pappus are arrayed makes even more of a difference to the efficiency of wind dispersal of the seeds than previously thought. It was an accepted theory that the resistance (drag) of individual filaments to wind makes dandelion seed so good at flying. It turns out that the way that moving air flows around each individual filament – and the filaments around it – creates a sort of stabilized vortex ring, allowing the seeds to stay buoyant for an impressive time and over long distances. You can read all about the physics of this amazing adaptation here.

Flowery Friday: Valentine’s Day edition.

I quite often set up theme days in the Alberta Gardening Facebook group I administer (especially during the winter, when we’re all suffering from cabin fever!). This morning, for some Valentine’s Day fun, I requested that everyone list their favourite red, pink, and white garden flowers/veggies/fruit.  I thought I’d do it here, too, and compare answers.  So far, they’ve posted amazing photos of petunias, daylilies, tomatoes, onions, raspberries, roses, poppies, tigridia, dahlias, peonies, and painted daisies…and they’re still at it.

I’ll start us off.  Next to sweet peas, roses are my very favourite flower, and I’m especially fond of the hardy roses that withstand our crazy cold climate and look pretty marvelous doing it.  The Explorer series is one example…and you have to admit these rich red double flowers of the beautiful shrub rose ‘Champlain’ are quite stunning.  (If you’re ever in the small town of Pincher Creek, in southern Alberta, you’ll see this rose featured in the Lebel Mansion rose garden, maintained by the Oldman River Rose Society).

Botany word of the week.*

Marcescence

This is the retention of the dead and dry leaves (and sometimes other parts such as fruit or seed pods) on some deciduous trees through winter.  Persistence, or as I like to think of it: a relentless lingering, somewhat along the lines of my cat’s queries for elevenses, twelveses, oneses, twoses (you get the idea).  Some trees seem to exhibit marcesence as  a trait – oaks are apparently one of them, although our climate isn’t mild enough for most Quercus spp. so I can’t perform a decent study on multiple varieties.  I did take a wander past the row of bur oaks (Q. macrocarpa) that grow near the train station in my neighbourhood, and while there were a few single leaves straggling on the branches, the trees were pretty much completely bare.  But we have to count that as an insufficiently representative sample (which, incidentally, also seems to be my cat’s views on the amount of food I give her).

IMG_3354

There are several theories on what causes marcescence, and what purpose it serves.  I believe in the case of this elm tree (and others like it in our city), the early frosts and severe cold we received back in September led to a failure of the formation of the abscission zone.  (This is an area of separation created by the natural weakening of cell walls between the petiole and the leaf.  While deciduous trees abscise in autumn, conifers do it pretty much all the time.  Another big difference is that deciduous trees normally fling everything off and conifers are, well, waaaaaaay more reserved). The leaves in my photo basically died on the spot and the tree wasn’t quite ready for that to happen. The wind took most of them off but some are still hanging around, waiting for spring like the rest of us.

Some researchers speculate that marcescence is a defense mechanism for the tree, protecting it from the munching of herbivorous predators such as moose and deer (who are going to eat fresh, tender young branch tips over icky dry foliage every time.  You can’t blame them, really).  Another idea is that the dry leaves act like little windproof shawls for the leaf buds, protecting them from winter desiccation.  Perhaps.  Still another thought is that the trees are deliberately generating their own mulch, dropping it at just the right time – spring, not autumn – for maximum moisture retention and as a source of nutrients.  Far-fetched?  Maybe, maybe not.

So what happens in the spring, when the buds of the new leaves break?  The marcescent leaves may remain on the tree, still waiting for a really strong wind to snap them off, or they may be pushed off the tree by the new growth, in which case they are instantly sucked up into a magical vortex so that you never have to rake them up.  

Then again, there are never any guarantees when it comes to magic, so have that rake handy, just in case.

*To be completely truthful, I’m not sure which specific day of the week the Botany Word of the Week will be posted.  Or that it will actually be posted weekly.  It may kind of float around and periodically pop up and surprise you.  Hopefully that’s okay.  

Book announcement! Well, actually, two books, one announcement!

HUGE, WONDERFUL NEWS! I spent much of last year working with my co-author, Calgary’s Cottage Gardener Janet Melrose, on the first two books in a new series called Guides for the Prairie Gardener. We are beyond thrilled that TouchWood Editions are publishing them, and the first two titles, The Prairie Gardener’s Go-To for Vegetables, and The Prairie Gardener’s Go-To for Pests and Diseases, will be out on April 7!
