Goldenrod Research

I've been trying to collect all the locally native Goldenrods. Some are quite easy, such as Solidago graminifolia, the Grass-leaved Goldenrod, but others are totally confusing.

In some cases the plants are so affected by growing conditions that I simply can't tell them apart. Solidago nemorosa, Grey-leaved Goldenrod, is usually quite easy to spot: short, one-sided wand-like flower spikes which nod over to one side, only a few small leaves along the stem, and no rosette of leaves at ground level at the time it blooms. So what the heck came up in the rock garden? The flower stalk was about 20" high, well-branched, with flowers all around each branch, and a healthy rosette of leaves on the ground.The individual flowers matched the description of S. nemorosa in J.C. Semple's Goldenrods of  Ontario, but the form of the flower stalk did not. It was in no way wand-like, much more what I'd call a plume. The rosette leaves matched, but should not have been there at the time the plant bloomed. Then there is a plant I brought back from an alvar I visited, which in fact looked exactly like this one except for being 4" high. It was growing in a huge field of Grey-leaved Goldenrods, all of which looked 'normal'. So is it a dwarf Grey-leaved or is it a regular one that got stepped on or chewed by a deer? Does S. nemorosa, when cut back early in the season, produce a plume instead of a wand?

I have a similar problem with a Goldie from Shaw Woods. When I try to key it out I get lost every time. It's not quite S. hispida, Hairy Goldenrod, yet it's not quite S. nemorosa either. It also bloomed very late so is not likely to be a form of S. juncea, Early Goldenrod, although the rosette leaves look a lot like it.

The answer: try to grow them all together in a test bed, so they all get the same conditions, and see how they do. Put a regular Grey-leaved, the dwarfish one, and the one from the rock garden all together and see if they are still different next year.

 So I dug a couple of beds for a Goldenrod Research Garden. Doesn't that sound grand? There is a spot below my rock garden which I have been planning to incorporate as a sort of transition between the rockery and the start of one of my woods trails and which I hadn't really done anything with yet. Full of weeds of course and I'll have to deal with them next year, but for now I just lifted the top six inches, dug up the six inches below that, added topsoil from the conveniently nearby pile, and called it a flowerbed. I'll put down some dark landscape fabric to make paths for now. One bed is for Goldenrods and the other for Asters. On the left you see the end of the two beds, looking a little like dog graves, and on the right you see the rosettes of some of the unknown Goldies. I've had them in pots for several months, so they should do fine. The smaller rosettes are some that might be Downy Goldenrod, S. puberula, a rare Ontario Goldenrod. They came from Constance Bay, growing on the trail and getting stomped by the horses that people like to ride through there. The two medium sized ones are the possible S. nemorosas, and the large one is goodness-knows-what from a marshy area. It's not S. uliginosa, Bog Goldenrod, but what it is I don't know. It didn't bloom this year but maybe next year. Gardeners are nothing if not hopeful!

Phlox Phacts

One more person says to me 'Oh, no good growing Phlox, they always run out and turn purple' and there might be an explosion!

Someone said that to me again yesterday, as we stood looking at my Hillside which still has quite a few phlox showing a few last flowers. There were white ones, pale pink ones, bluish-mauve ones and a dark almost red pink. Earlier, there had been the almost purple 'Nikki' and a variegated-leaf one with medium pink flowers as well. The Phlox did very well this year - they seemed to like the heat! If she had said only the 'run out' bit, I would have tried to explain about Phlox being hybrids and their seeds not necessarily giving plants like the parent, but once she threw in the other bit about them coming back 'purple' I gave it up as a bad case. One thinking error I can handle, but two are beyond me.

The original Phlox paniculata, what you might call your Natural Phlox, was magenta. Perhaps a washy magenta, but magenta. Not purple! Purple is darker, bluer, much closer to indigo than to red. Campanulas are sometimes purple, as are some grapes and some plums. The hybridizers have done their magic tricks and given us Phlox in a range of colours, all of them charming, but none of them really purple.

Just for fun, here's a picture of a late Harebell, Campanula rotundifolia, in the rain. All pictures lately have been 'in the rain' because I'm convinced it hasn't stopped raining since middle August. Ok, and a picture of Geranium sanguineum just to have a true magenta to look at.

A Very Fine Day

Had the most excellent day! Packed my larger backpack with essentials such as camera and lunch, and headed down to Marlborough Forest. This is a huge natural area, something like 45 by 60 kilometres, completely inside the City boundary. It's a mosaic of City-owned, Province-owned and privately-owned properties, more or less administered by the City according to Provincial regulations, with the co-operation of a number of groups like Ducks Unlimited, the Ontario Snowmobile Association, the Rideau Trail Association and others. In practice the deer hunters and the ATV enthusiasts do what they want. This means you stay out during hunting season!

But it's a great place to explore an alvar. The area I went to, off Paden Road near Burritts Rapids, is an enormous alvar. It took a bit of a walk to get in to it, and walking on the chunks of rock they put down to make the trails is no joke, but once I got there it was great fun. Completely flat as far as I could see, with clumps of junipers interspersed with open grassy areas and the occasional low willow or alder clump. What I was looking for was Solidago asteroides, the White Upland Aster or White Goldenrod. It has had a number of names, but the botanists now put it firmly in with the Goldenrods. I have one plant in my garden, grown from seed, but I really wanted to see it growing 'in the wild'.

There were thousands! The picture on the left shows a typical plant, about 16 - 18" high, growing in with the sparse grassy alvar plants.

White Goldenrod, Solidao asteroides


There were also a great many Fringed Gentians, Gentianopsis crinita, Slender Gerardias, Gerardia tenuifolia, Grey Goldenrods, Solidago nemorosa, a tiny purple flower I can't find in my field guide, and few just-opening Nodding Ladies Tresses, Spiranthes cernua.

Fringed Gentians - several colour forms
Slender Gerardia
Nodding Ladies Tresses
An almost white Fringed Gentian
A mystery! The plant is only 4" high.

OK, I'm having trouble arranging these images! But the captions should explain them. If you know what the tiny purple thing with the startling blue stamens is, please tell me!

The pale Fringed Gentian was a real find, too. I didn't get good pictures but enough to prove that I saw it. Most blue flowers have the occasional white clone. I'd love to have this in my garden, but I'm not having any success growing Fringies, so far. I've had the seed germinate but lost the seedlings to damping off, I've have little seedlings which I forgot to check on and which died (I assume) in the first dry week, and seed sprinkled in a wet area down along the driveway has so far not resulted in sheets of blue. Maybe next year? They are biennials so maybe I'm just not seeing the new plants. I searced the Paden alvar area for next year's Fringies, but couldn't find anything that looked like a gentian rosette. Do they only start to grow late in the season?

It was getting late by the time I hobbled back to the truck. And I did hobble. Those miserable rocks on the trail were so hard to walk on my feet were so sore I could hardly get my hiking boots off.
Then, just as I was ready to drive off, I happened to look over my shoulder behind me, and saw something I've been looking for for years. At first glance I wasn't sure it was what I thought it was, but I had to stop and take a look. Yes! A white (almost white, anyway) form of New England Aster!

It was growing on a mound of rubble obviously pushed back by a bulldozer or some such machine, and right beside the trail the dirt bikers had made to get around the 'no vehicles allowed' gate across the trail. I admit it, a small piece of the plant came home with me. A research sample! I potted it up, and so far so good. These asters are really easy to grow so I am hopeful.. It may be a purchased plant discarded there or it may be a lucky accident, but whatever it is, I'm delighted to have it.

What a day!

An Icy Job

Trimmed 'Iceberg' yesterday.

That is to say, I was the one with the secateurs, and 'Iceberg' was the rose bush that got smaller.

I can't really say I pruned it. The darn thing was sprawled across both of the paths that meet at its corner, lying in wait for any ankles that might be going, or trying to go, by. It is much too big and too sprawly for that spot, but is so healthy, and blooms so exuberantly for nearly a month every summer, that I just can't remove it. I didn't intend to have a monster rose in that corner but there it is, sort of like an Uncle Fred who has to be invited to family events but whose behavior than causes eyes to roll and voices to sharpen. I actually wanted 'Seafoam', but the nursery man told me 'Iceberg' was just the same. Right.

I thought at first maybe I could get in underneath and remove some of the longer canes, but that wasn't possible. It was a tangle of canes, most of them over 6 feet long, and there was no way I could get a hand or arm underneath without serious injury. Iceberg is one of those bushes that has stiff curved thorns, which catch and grab whatever gets close. The many canes all criss-cross into a dense tangle. Reaching in and cutting out canes at ground level is nerve-wracking. You work your hand in very carefully, secateurs at the ready, and a twig springs back and embeds itself in your wrist, you jerk your arm back and three more twigs catch hold. Since you're holding several canes back with your other hand, you now need a third hand to work the first one free....  I had heavy leather gloves on, and a long-sleeved shirt, but even so I got half a dozen long scratches and any number of pokes before I was done. After that I wasn't about to  carefully cut back each spent flower cluster, so just cut everything that extended beyond an imaginary circle about 6 feet across or higher up than about 3 feet. Now it looks like a turned-out pudding, but at least you can get past it without bloodshed. Usually.

I wonder if it was 'Iceberg' that gave someone the idea of the 'pavement rose'? Or is mine the only 'Iceberg' in the world that wants to be a ground cover?

Yarrows

I've always liked the tall Yarrow called, I think,' Gold Plate'. I grew some from seed and put a group of them in the hillside garden and I've liked them there. They provide a bit of muscle in what could be a flabby setting of Phlox, Shasta Daisies, blue Veronica and such.(There are also a lot of Coneflowers in that border, but they are over to the one end.) The Yarrow's fairly sharp mustard yellow is a bit jarring, but there is such as thing as too much good taste.

A plant of wild Yarrow, Achillea millefolium, wasted no time in joining its cousin. Since it bloomed a very clear crisp white I left it. It's not visible from the front of the border, but when you go around the back, up the rock steps, it's there and fits in well with it's slightly shorter stature, dusty green foliage, and rather open flower clusters. A Yarrow is of course one of the Compositae, so what looks like a flower is really a group of small flowers, called florets, each of which is itself composed of a group of even smaller flowers. Confused? Sorry. The thing we call the Flower, in a Yarrow, is a corymb, and is composed of multiple Heads, each of which is composed of two types of flowers - Ray flowers, and disc flowers. Each one is actually a tiny Daisy. There is no end to the designs, combinations of designs and groupings of combinations of designs in nature.

Just as there is no end to the hanky-panky that goes on behind the scenes.

My yarrows have now produced an intermediate form. It has the shape and size of 'Gold Plate', in fact it might even be a bit taller, the greyish foliage of the Wild Yarrow, and a colour right in between the two. It is a soft but distinct yellow. When I look at the individual heads closely, I see that the disc flowers (the ones in the centres of the flower heads) are pale yellow, while the ray flowers (the 'petals') are white.


I just checked the books. Apparently, 'Gold Plate' is a variety of Achillea filipendulina. Also listed is a plant with pale yellow flowers like my seedling called A. 'Taygetea' which it describes as 'a hybrid of uncertain origin, probably between A. millefolium and A. clypeolata'. Hmmm. I don't have A. clypeolata around, as far as I know, and in any case the leaves on my plant look different from those in the book. The leaves on my plant look exactly like the leaves on 'Gold Plate' only with the colour of the A. millifolium leaves.I can't tell whether the ray flowers of the plant in the book are white like on my plant. In any case, I guess it's safe to say my plant is 'of uncertain origin'.

The Yarrows are coping well with the drought this summer, another reason to like them.

They can be cut right to the ground after they bloom (and they stay in bloom a good 3-4 weeks), or you can cut each flowering stem off at ground level. If you have only a few plants and enough time, you can cut the individual stalks, but if you have lots of plants or little time, you can just give the whole thing a bean shave with the garden shears. My kind of plant!

The pink, red and rust coloured Yarrows, by the way, are of quite different parentage, and behave very differently, at least for me. They are much shorter, need to be divided every year to keep them from running out, and do not do at all well in a drought. I keep one clump going in the Herb Garden just to be able to say I have Yarrow.

A Word from the Trowel

Hi Folks,

This is Lis's Trowel speaking. If she's going to leave me out all night with my head stuck in the sand in the Cactus Patch, well, no more Ms. Nice Trowel, I've kept my mouth shut long enough. Who do you think does all the work around here, anyway?And don't tell me not to be bitchy, I'm blunt at one end and sharp at the other so what do you expect?

What's with this Cactus Patch thing, anyway? Doesn't She know that this is zone 4? Cactuses (yes, I know the La-di-das say 'cactii', but that's not us, is it?) are desert plants. They do not grow where snow covers them about half the year. They like to be hot, not cold. This is not a desert, except maybe a cultural desert. Mind you, She does listen to the CBC in the Studio, maybe that counts for something, but given how little classical music is left in their programming, I'm not sure that it's much. It's so bad that in the afternoon She turns the radio off, which leads to Her humming while She works.... not pretty, I assure you. But I digress. My point is, it's not cactuses that want to grow here.

Bugloss wants to grow here. Viper's Bugloss, Echium vulgare. A perfectly good plant with no airs or graces. It has nice blue flowers, too, which you can't say cactuses ever have. Oh, and it's prickly, too. So, why does She insist on pulling it out and leaving those Opuntia fragilis wusses in the ground?

Opuntia fragilis 'Potato'. Sheesh. Who ever heard of a plant called 'Potato'? Except maybe a potato, I guess. A lumpy green thing, that's all it is. Never a flower, nooooo. 

Another thing that wants to grow here is Bladder Campion, Silene cucubalis. Now, there's a name for you. Sounds like another vegetable, doesn't it. Anyway, She keeps trying to get rid of it but it's pretty smart. It has its roots down way deep and they're kind of grippy so it's impossible to pull them up. Hee hee. Even spraying them with a nasty weedkiller doesn't bother them too much. They come right back. I like those guys, tough is the word. Not like that Opuntia polyacantha that She keeps fussing over. It shrinks every winter and looks like s..t in the spring but thanks to all the fussing it does look a little better by about now. It did bloom once, too. For about three minutes early one morning before anybody was out of bed to actually see it.

Crown Vetch, Viccia cracca, wants to grow here too. It gets pretty cosy with Opuntia basilaris var. aurea, which is smart because She can't hardly get it out from between the prickles without pulling out most of the cactus pads. At least that thing blooms. Large yellow flowers, which I think look pretty good with the blue Vetch flowers. Fetching, in fact.

Oh, apparently Crown Vetch, Bladder Campion and Bugloss aren't 'native', whatever that means. Well, excuse me. 

Oh, oh. I hear we're going to weed the Cactus Patch this afternoon. Ow, my poor skin.... ow, my handle, ow....


White Alkanet

Like a lot of collector-gardeners, I like the unusual forms of things. If the plant is normally green, I want the yellow version. If it is normally yellow, of course I want the green version! (And if it comes in seven different colours, I want all of them, but that's a different story.)

So while I like the regular dark blue Alkanet, naturally I like the one with white flowers even better.

Now Alkanet, Anchusa officinalis,  an Herb sometimes used in dyeing, is not a particularly impressive garden plant. The leaves are raspy and mid-green, the stems are lanky, and the flowers are small. Numerous, but small. Still, I like it because the stems weave themselves in with other plants in the border and poke their bright blue flowers out here and there. They look pretty good with Daisies, Shasta or otherwise, or among Lamb's-ears or between stout Peony bushes. This spring, they happened to bloom at the same time as some very late tall white Tulips, and the effect was something to see. They do however seed around badly. I pull the ones I don't want, obviously, but I've been leaving some that bloomed in either paler blue or white. In one area I have white ones pretty much coming true from seed. Heh, heh.

(If anybody would like some seeds of White Alkanet, drop me a line.)
