I have bad news and good news. The bad news is there’s a fungus among us. Impatiens downy mildew (Plasmopara obducens), the mysterious ailment that denuded and killed almost every busy Lizzie (Impatiens walleriana) back in July or August of last year, is here to stay. It’s in our soil now and unlike other downy mildews that attack other species of plants, this one is happy to overwinter here in the soil. Add to that, our native woodland wildflower and poison ivy remedy, jewelweed (Impatiens capensis), obligingly harbors it without dying or even becoming particularly disfigured by it.

This coming summer impatiens downy mildew will spread by spores that germinate in humid conditions, just as it did last year. Four hours of standing water (a sprinkler system or a good soaking rain) is all it needs to move from soil to plant where it then becomes airborne. And there is no fungicide that will control it once lesions form on the leaves. Despite that, some growers are determined to keep selling the species that has been their bread and butter ever since petunias fell from favor. But their impatiens will have to be pumped full of expensive systemic fungicide in order to ensure a mere six weeks of immunity in your garden. It’s a heavy price to pay for what has been one of the least expensive and longest blooming bedding plants. Expect that cost to be passed along. Other growers are boldly refusing to propagate an ill-fated best seller and will be offering healthy and more sustainable alternatives instead. And meanwhile, breeders are working to create downy-mildew-resistant impatiens. But don’t hold your breath. They’re still years away.

The good news is it’s time for a change. Monocultures of impatiens have been planted in industrial parks, corporate and private landscapes, urban and suburban yards for quite long enough. In fact, being planted so exclusively and densely sped their demise, first in the UK back in 2003, then in greenhouses, Florida, up the Eastern Seaboard, and all the way across the more humid portions of the country in the last couple of years. And I, for one, am looking forward to seeing a little more variety in yards, gardens, and landscapes in the years to come. But then, I have never been impatiens’ biggest fan.

I understand that a flat of Impatiens walleriana was wicked cheap to buy. But didn’t those starts need water and fertilizer all summer long? I understand that, if given those things, impatiens bloomed non-stop, and in the shade no less. But did you ever see a bee work the blossoms? And didn’t you get a little bored with them by August? I have never planted them in my own garden and we don’t use them at Blithewold because—and this, really, is the good news—there are so many other gorgeous plants in the world. Some are just as, if not more, colorful; a few might bring out the gardener in non-gardeners; others will be much easier to care for. That’s the truth.

My advice to hardcore impatiens devotees: If you can’t live without them, try them in hanging baskets. And for your garden beds, rather than choosing one alternative stand-in from a long list of shade-loving bedding annuals that includes (and is by no means limited to) New Guinea impatiens (those noisy cousins are immune), begonias, torenia, lobelia, coleus, browallia, oxalis, and nicotiana, plant a kaleidoscope. Variety isn’t just the spice of life, it’s more sustainable. Celebrate all the months of summer — and treat yourself to late season surprises too — by planting tender perennials like spurflower (Plectranthus ciliatus) and fuchsias that bloom into fall and can even be overwintered indoors. And then why not add in a few perennials with fabulous foliage like heuchera, hosta, lady’s mantle, brunnera, pulmonaria, and lamium? Nowadays they don’t cost much more than annuals and, more often than not, live to brighten your beds and borders for years. Please don’t just take my word for it. Ask at your favorite local nursery for suggestions. (No doubt, they will be more sympathetic than I.) And take the good news over the bad.

Apologies to any of you who might have already read this. — It was first published last week by East Bay, RI and South Coast, MA newspapers for my column, Down to Earth.

More changes are afoot in the potting shed than just a remodel and reorganization. We are entering the modern age finally and ordering seeds on line rather than sending them off by mail. But even though we’ve decided to embrace technology for the sake of faster gratification than waiting for checks to be issued and the mail sent both ways, I still think reading a paper catalog is easier and more fun than staring at web pages. –That said, I can understand why some plant and seed companies have gone entirely on line and I applaud them for not wasting trees, ink, and postage on me when clearly the world is moving away from those things. So for however long it takes for the rest of us to prefer the feeling of an e-reader in our paws rather than a bound book, paper catalogs will have a welcome place on my lap.

Last year I placed our first order (in my time) with Chiltern Seeds in England. I searched on line for what we wanted — certain grasses and sweet peas that weren’t available through our usual sources — and was only mildly annoyed when some of their plants were listed without pictures. After all, a google images search is only a tab away. But this year they sent us a paper catalog. At first I was overwhelmed by it because the skinny onion-skin pages hold 4000+ plant descriptions, all but 9 without pictures! But after flicking through quickly, I started reading from the beginning and found the reward: tucked here and there amongst perfectly illustrative descriptions is humor, personality, and interesting information.

I learned that Dispsacus fullonum, which I have been calling Fuller’s teasel (because that’s what its species name implies) is in fact “common teasel”. The teasel actually used by fullers to card wool is Dipsacus sativus, whose dried flower heads “are a miracle of nature” with ” hundreds of tiny, stiff, downward-turned hooks amazingly and geometrically arranged.”  The description of Eryngium planum ‘Blue Glitter’ made me nod and snort because “the writer likes this one!” and after calling the flower heads “innumerable,” he actually counted 85 on the stem on his desk. I never noticed before that Silphium lacinatum orients its leaves to the poles. (I also didn’t know it’s called compass plant, pilot weed, and polar plant.) So cool. And I loved that towards the end the writer looked like he was getting a little punchy. The description for Viola ‘Cats’ begins,

“It is no secret that the writer likes his cats: as he pens these words, there’s a white porcelain cat glowering down at him from the mantlepiece warning him against making purrfectly awful puns about purrfect faces or even suggesting having a purr of these lovely Pansies in pots outside your front door. So he won’t!”

Like turning the last page of a good book, I was a little sad to finish that catalog. But we placed a big order and have a whole season of our own opinions about those plants – mostly sweet peas and primroses – to look forward to.

Do you still read plant and seed catalogs cover to cover? Do you have a favorite?

There are always things we want to change about every garden. Plants we want to move. Plants we want to remove. New plants we want to plant. We don’t just want the gardens to change every year (which we do because we think that makes it more interesting for us and for repeat visitors) but we want to get it right. The North Garden especially. It doesn’t actually change a whole lot from year to year (aside from its latest redesign) because we have settled on a palette of colors that suits that garden and its view. It just needs tweaking from one year to the next to make sure that it’s beautiful from one hot summer week to the next and in peak bloom from May to October. And of course we stack the deck as we do in each garden (except maybe the Rock Garden) with annuals and tender perennials that will fill it to the gills with late season color. (Spring and early-summer color themselves.)

But right now the North is quieter than it should be and than we’d like. The petunias that bloomed so beautifully through July and into August have apparently succumbed to the budworm. And something mysterious has happened to our ever-reliable dahlias, particularly those in the front row. They’re all budded up with nary an open flower on a single plant. With the weather being so soft and lovely (aside from last night’s storm) we feel we’re being cheated one of the prettiest times of year in that garden. But Gail and I are harsh critics when we have our notebooks out. When I looked again through the camera lens I saw that the Aster ‘Lady in Black’ has woven its dark foliage beautifully through the garden and will bloom any second now. I noticed that the Coreopsis ‘Red Shift’ and Phlox ‘Natural Feelings’ that the volunteers deadheaded a couple-three weeks ago are putting on a fresh show. The heliotrope, Zinnia angustifolia (which deserves its own post), Ageratum ‘Blue Horizon’ and its doppelganger, hardy ageratum (Conoclinium coelestinum) are all blooming to beat the band. The back row dahlias, ‘Golden Cloud’, which were recommended by a visitor last year are thumbing their nose at whatever scuzz the front row dahlias have gotten and are gooooorgeous.

Nonetheless, we’re working on a list of plants to move and remove for a showier September next year. We might try to save room in the budget to replace petunias with something else (what else?) when they go by and maybe we won’t rely quite so heavily on our favorite little orange dahlias. We’ve made mental and actual notes to remember to cut the phlox and coreopsis back again next year in early to mid-August because their second flush is almost prettier than their first.

Are you your garden’s harshest critic? What will you do differently next year? Have you had similar trouble with dahlias? Any guesses why?

As much as I love the freshness of a June garden, September is my favorite month. Some visitors seem surprised that we “still” have so much color but I can’t imagine it any other way. The gentle light and the beautiful cool blue days demand that we be outside reveling in exuberant color. We definitely plan for this time of year (in truth, for the whole summer into fall season) to be stupendous but it doesn’t take much – a few annuals like zinnias, ageratum, and alyssum; and a handful of tender perennials like dahlias, salvias, angelonia, and plectranthus and you’re golden. Or the garden is in any case, especially in the slanted light of September. Even with roses, delphinium, asters, and euphorbia (re)blooming in the Rose Garden, it wouldn’t be nearly as spectacular without the annuals and tender perennials giving them a boost. I know a lot of gardeners choose not to buy plants that won’t survive the winter outside but I think those plants are worth every penny (and seed annuals like zinnias really do just cost pennies) because they’re the ones that carry the garden so effortlessly past its usual early summer peak well into the prettiest months of all.

And of course, some of them can survive the winter and carry whatever we spent on them into the next season too (and the next after that and the next…) We’ve started taking cuttings of some of our favorites like porterweed (Stachytarpheta mutabilis), cigar plant (Cuphea spp.) and heliotrope. We’re lucky to have the greenhouse for overwintering them but sunny windowsills would work too.

Is your garden as colorful as you’d like it to be this month? Do you use annuals and tender perennials too or do rely on late-blooming hardy perennials and shrubs? For a look at a whole world of colorful September blooms, check out May Dreams Gardens Garden Bloggers Bloom Day (September 15).

Do you remember the scene in Grosse Pointe Blank where Joan Cusack’s character describes going to her 10 year high school reunion? She said, “It was just as if everyone had swelled.” I couldn’t help thinking of that when I walked through the gardens this morning after 2 weeks away. It was just as if the gardens had swelled. Between hot days and a whole bunch of much needed rain, the garden grew at least another whole dress size. I barely fit down some of the paths. I wish I had taken before pictures of the vegetable garden because I could have sworn that the gourds hadn’t even thought about reaching the top of the arbor and the corn still looked like wispy little grass.

And in a mere 2 weeks, summer became late summer. How I know is because the Joe Pye weed and rudbeckia are in full bloom and the insect and bird activity has reached a frenetic crescendo. This morning I watched a cheeky little hummingbird bully 2 goldfinch away from “his” bamboo grove. Butterflies are everywhere and there are bees and wasps of all shapes and sizes making every garden buzz. Loudly. I hesitate to say it, but I think the light is even starting to change.

I was right about the Lycoris – they have mostly gone by without me seeing them. But the lotus put up more than one bud as it turned out, and I’m thrilled to have caught this one’s glory. And the Sophora (Styphnolobium japonicum) just outside the Rose Garden moongate is in full bloom and just starting to drop.

I still feel like I missed a lot while I was away and yet I’m certain I have a better appreciation for the changes than I otherwise would. Do you like leaving your garden in order to come back to it with fresh eyes or are you tuned in enough to notice the changes — and fully appreciate them all the way through?
