I have heard that there are gardeners in the world who don’t love roses and I think I can almost understand why. For starters, they’re pretty common and might not appeal to gardeners who prefer oddities and rarities. To that I’ll just show one of my annual portraits of Rosa chinensis ‘Viridiflora’ (below left). That plant definitely satisfies my lust for the weird. There are even roses for gardeners who prefer native plants to exotic ones. (Alas I have no picture of R. virginiana because we don’t have that yet.)

I know some gardeners don’t like roses because they’re high maintenance. No argument there unless you consider a rose like redleaf rose (Rosa rubrifolia/R. glauca – above right), which only needs to be cut back hard in early spring and then left alone to bloom once and make gorgeous orange hips. But I happen to enjoy maintaining roses. There’s nothing like deadheading in June when the dropping petals are silky soft and full of perfume. I could spend whole days happily deadheading (and have the thorn scars to prove it). And I Zen out raking black-spotty leaves, which in recent years we haven’t had to do as much of because the roses are so healthy.

But I’ve come to the crux of it. Roses are notoriously sickly and difficult to keep healthy and pest-free without spraying toxic chemicals in all directions. Thank goodness most of us have become too health and environment-conscious to be willing to do that anymore. Rather than chuck all the roses, which isn’t an option in our book, we concentrated on making them healthier from the ground up. Our efforts (replacing sick roses with disease resistant varieties; compost for the healthy, fertile soil they require; 3 applications of organic fertilizer through the season as they break and bloom; and a generously donated irrigation system to keep them from drying out and becoming stressed and vulnerable to insects and disease) have paid off in non-stop blooms and deep-green leaves. We also think roses look their best when they’re used in a mixed garden, planted with a wide variety of companions. Packing them into a garden might not give them the airflow they like but they bloom away just as happily and other plants can help disguise any unhappy foliage and naked stems.

I wouldn’t want to try to convince anyone who doesn’t love roses to give them a chance but I can’t help thinking that for anyone on the fence, our Rose Garden presents an argument in their favor – living proof that they can be healthy, relatively easy to care for, and even a bit out of the ordinary. Do you like roses? Have you given up growing them or found a way to enjoy them?

I finally bought my very own copy of Ken Druse’s latest book Natural Companions: A Garden Lover’s Guide to Plant Combinations and if you don’t have a copy yet, it’s worth dropping everything else – plant those annuals later! – to pick it up. (I ordered mine from my favorite local bookstore and beat feet to get it as soon as it came in.) Truly, you might never look at your garden and the plants in it the same way again. I appreciated Ken’s reminder to pick flowers and foliage to see what would look well together but Ellen Hoverkamp’s digital scans of those pickings are exquisite. And then Ken takes it several steps further to illuminate plants that not only look well together but go together in various other ways, whether they’re related by “blood”, color, place, habit, use, and so on and on for well over 200 beautifully written and photographed pages.

I don’t have Ellen’s patience – or her brilliant artistic eye – or her equipment – to ever be able to create such amazing compositions but I have already started to notice the garden’s own arrangements and natural companions with a fresh eye. Some of these combinations (related more by good looks and cultural requirements than anything more thought-provoking) were planned but I think most were either lucky guesses or pure wind-blown serendipity. (Mouse over for captions, click on for larger views.)

What combinations of plants go well together in your garden? Do you think about different kinds of plant relationships when you’re working on your garden’s design?

For this mid-May Garden Bloggers Bloom Day hosted by Carol at May Dreams Gardens, I’m going to postpone the usual list of all of the amazing things that are blooming suddenly all at once and go into euphoric raptures about a single fantastic genus that has been blooming for a while now. One of them even kept last year’s blooms all winter.

Of all 2000 odd species of euphorbia in the world, we only have a half-dozen or so on the property. In a way that’s plenty because the ones we have are pretty great, and on the other hand it’s not nearly enough because who wouldn’t want more?

At the top of my favorite spurges list is Euphorbia x martinii ‘Ascot Rainbow’. Not only does it have stunning multi-colored foliage and fabulously intricate flying-saucer blooms but it looked fabulous through the winter. In fact, it still looked so good this spring that we weren’t sure if we should cut it back. We decided to cut a few plants here and there to within a couple inches of the ground, and we left a few standing, and are planning on using their older stems for arrangements. That’s one of the greatest things about euphorbia: they make really great nearly ever-lasting cut flowers.

Euphorbia amygdaloides ‘Purpurea’ (below left) spreads generously (rhizomatously) in shade but we have it in full sun too in the Rose Garden. We transplanted bunches of it around from underneath the chestnut rose and it pouted for a good year (or was it two?) before finally looking stunningly settled. Never give up on a euphorbia. Last year we also planted ‘Craigieburn’ (below right) in the cutting garden I think I like that one even better for the subtle range of colors in its foliage and the extra acid in the green of its flowers.

E. longifolia (below left) has been seeding itself around the North Garden and Display Garden for years, which is great because we always have the option of using it where it lands or hoiking it out to make room for something else. After it blooms (it stands about 2′ tall) we cut it back hard to encourage a new flush later in the summer. That’s a dangerous job because the sap of this one seems particularly caustic. Anyone who has ever gotten a bright red burning and wicked-itchy rash from spurge learns pretty quickly to wear body armor to work with it.

The cushion spurge (E. polychroma – above right) in the Rock Garden hasn’t self-sowed although it’s supposed to and I wish it would. It’s too cute. We also have ‘Bonfire’, which has bright orange blooms and red foliage, up in the Display Garden but we don’t have it in enough sun to show itself off properly.

I could go on because we also grow sticks-on-fire pencil cactus and crown-of-thorns in the greenhouse and those go to show how varied the genus can be. But I’m stuck on spurges. Which ones do you grow – or wish you did? For a look at what else is bloom (besides euphorbia) all over the country and the world, click on the links listed here.

When it’s pouring rain outside, the greenhouse is definitely the best place to be. It’s not exactly warm on a gray day and it’s not completely dry either but it is full of summer’s promise. Visitors can’t help asking if the plants are for sale. It’s a good question because I’d want them for my own garden too. But, alas, they are not for sale – at least not here. Everything in the greenhouse is destined for Blithewold’s gardens. We have some new plants that I’m especially excited about and just in case you might be too, here’s the scoop on where you can find them:

Avant Gardens is selling a new (it’s new to us – is it new to the world?) hummingbird mint – Agastache ‘Summer Glow’. If it glows anything like the picture on the tag I’m smitten and I don’t even love yellow. Those will go in the North Garden. They are also selling this adorable violet with pewter leaves (Viola walteri ‘Silver Gem’.) Anything that looks like jewelry really needs to be planted in the jewel box of our Rock Garden.

Annie’s Annuals, a mail order source on the other coast, is selling a hook sedge (Uncinia uncinata ‘Rubra’) that promises to turn garnet red in the garden. I suppose they should go in the Rock Garden too but I’ve had my eye on them for a necklace of containers. A speckled leaved honesty (Lunaria annua ‘Rosemary Verey’) from Annie’s will find a spot in the Display Garden and I hope-hope-hope it comes true from seed next year.

Dahlia ‘Kaili’, which came in exactly a month ago as a rooted cutting from Corralitos Gardens, another mail order source from California that specializes in the prettiest dahlias, is already fulfilling its promise. We can be certain that it, ‘Golden Cloud’, ‘Granville’, and ‘Bishop of York’ will be gorgeous planted in the North Garden.

With more and more people planting vegetables, they are easier and easier to find as starts at almost any nursery or farmer’s market. We grew these tomatoes from seed from several different sources including Baker Creek and Johnny’s. I can’t wait for my first Sungold snack…

Have you found plants you’re excited about this year? What are they, and where can we buy them?

Word from our Visitor’s Center is that visitation drops off in May. I can’t imagine why. We might not be promoting daffodils anymore but there is still so much going on here. More and more every day. This week, after the Wednesday volunteer group (The Rockettes) planted the sweet peas along the cutting garden fence, a few of us went down to the Rock Garden. I think it’s safe to say that it has never looked sweeter or more filled in and colorful. And there really wasn’t much for us to do but marvel at its display. I’d hate for anyone to not see it just as it is right now. Pictures don’t do it justice but since the internet prevents me from grabbing you all by the hand to pull you down there, they’ll have to suffice. And if you possibly can carve some time out of your weekend (Sunday is forecast to be the better day) by all means, come see it for yourself. And take a walk by the dove tree on your way. And as you leave, say hey to all the tiny tadpoles keeping warm on the pond rocks.

The Rock Garden highlights for me are an Erigeron glaucus ‘Sea Breeze’ (second picture from the bottom) that has been steadily increasing since we planted it a couple of years ago but I don’t ever remember it blooming before. So pretty! And good old tiarella. Where has this plant (Tiarella ‘Elizabeth Oliver’) been all my life? Suddenly I’m totally in love. We planted these as plugs, also a couple of years ago, and they are really taking off now, each one as pretty as a picture.

What’s going on in your spring tapestry?
