Best of the New Annuals

Like a lot of garden writers, I get to try out newish plants, courtesy of plant wholesalers. For several years, I’ve gotten plants from Proven Winners and invariably there are indeed some winners among the plants.

This year, I grew two annuals from the sample plants that have grown really well, and definitely are among the “best of” plants for their categories.

He’s not visible in this shot, but there was a bee all over these guys when I took the photo.

Playin’ the Blues salvia — Part of a series called Rockin™, these deep purple-blue salvia have gotten zero attention from me, but have bloomed and bloomed and bloomed all summer long. Even in August, the foliage looks healthy and shiny and the flower spikes keep growing. I planted these in a bed that I’m planning to use for strawberries next year, so I basically threw whatever into it this year—the garden equivalent of a junk drawer. (That’s why there is a monster squash edging its way around the salvia.) The bed gets part-sun at best, and other than a little slow-release fertilizer in the planting hole, nothing else has been done to them.  Pest and disease free, the bees seem to love these plants.  The foliage looks better than any of my other annuals. They are winter hardy in USDA Zone 7 and higher, so for cold-climate gardeners these will have to be annuals.

Superbells® Over Easy™ is a Calibrachoa hybrid that does really well in containers. I planted these with some lilies, which have bloomed already, and some marigolds grown from seed. The white color with a dot of yellow at the center does remind you of over-easy eggs and the plants brighten up whatever else they are planted with. White is such a great color for adding contrast to the garden. Unlike some of my other petunias and calibrachoas, I did not need to give the Over Easy plants a mid-season trim in order to keep them blooming. The plants don’t get huge — staying under 12 inches tall, but they look neat and perfect flopped over the edge of a terra-cotta container.

Marigolds pair well with this yellow-centered calibrachoa, which is called Superbells® Over Easy™a new plant from Proven Winners.

Orange is the New Purple

I have always loved purple in the garden for its deep hue and because many plants I like for other reasons (baptisia and anise hyssop, for example) have purple flowers. But this year, I decided to grow a few orange annuals, and I may have to change my new favorite color. I first heard about the power of orange during a garden talk by Eric Johnson, one of our Northern Gardener columnists.

This ‘Torch’ Mexican sunflower (Tithonia) was grown from seed. I love the bright orange, especially on a gloomy, rainy day.

According to Eric, orange is a color that brightens up drab spaces, and it certainly is working in my patio/vegetable garden area. On the site of a former garage, I’m growing vegetables in raised beds. The vegetables are, of course, mostly green, and the perennials I planted this spring are still getting a foothold in the clay soil and aren’t blooming much. I have a ‘Blue Heaven’ morning glory that is covering a trellis and part of the back fence, but that hasn’t bloomed at all yet — so again, more green.

Marigolds pair well with this yellow-centered calibrachoa, which is called Superbells® Over Easy™a new plant from Proven Winners.

Enter orange, in the form of several containers filled with orange marigolds, orange pansies and Mexican sunflower (Tithonia). I bought the pansies as a six-pack early this spring, but grew the others from seed. The ‘Torch’ tithonia came from Seed Savers Exchange and has been a magnet for monarch butterflies in my backyard.  The plants are more than 4-feet tall, with large leaves and several flowers per plant. Next year, I may plant them as a low hedge along one of my fences because they are big and pretty.

The marigolds are also from Seed Savers, a variety from the 1930s called Starfire Signet. The blooms are in shades of yellow, orange and red and they grow at least 12 inches tall. We ran an article on marigolds in the May/June issue of Northern Gardener and that got me inspired to use more marigolds and to grow them from seed. They are very easy to grow and the results are warm and fun.

I may have bought this marigold as a plant. It’s super pretty though.

The last orange annual I’ve been growing is an old-fashioned nasturtium called Lady Bird. This one has not done as well as the marigolds, but in a few of the containers the orange-yellow blooms are adding to the show.

Orange can be too much if you have a lot of other colors in the garden–especially reds and pinks. In this area, I’ve got mostly green with some white blooms and (of course) a touch of purple. So far, it’s been a fun departure from my usual color palette.

What’s your favorite color to brighten the garden?

I paired these orange pansies with a Ginger Wine ninebark in a container. I love the ninebark and will be planting it in the landscape this fall.

Blooming in November?

New Plants for 2016: First Impressions

I’m one of those lucky garden writers who receives plants from several plant wholesalers to test before the plants are introduced to the public. The companies—Proven Winners and Bailey Nurseries this year—use feedback from writers (and many other plant testers) to make sure the plants will perform well in home gardens.

These are plants that you will likely see in nurseries and garden centers next year. Maybe I’m getting better at growing these new plants or maybe this is just a particularly good year for introductions, but the plants I tried this year were overwhelmingly great.

Here are five that you may want to look for next year.

Campfire™ Fireburst bidens was one of the most commented on plants when my garden was on a tour earlier this summer. The bright yellow and orange flowers add a dainty element to containers. The blooms were prolific and the plant bloomed most of the season. They took a bit of a break in August, but revived with some fertilizer and more attention to watering.

Superbells® Holy Moly™ calibrachoa is a cousin to Superbells® Cherry Star, which I loved for its bright pink and yellow petunia-like blooms. Holy Moly is predominantly yellow with red-pink accents. It is a prolific bloomer and looked fantastic in several containers. This calibrachoa is known for continuing to bloom even in the fall, and that certainly proved true in this warmer-than-average October. The plant took a break in September, but has been blooming away since then.

container with sedumAnother container plant I really liked was Lemon Coral™ sedum, a  short, chartreuse annual sedum. I used the plant in containers and it added a textural element as well as brightness. This sedum can handle part sun and is great for brightening up a shady corner. Some other garden bloggers have commented that the plant is a bit too aggressive, but I grew it only in containers and did not find that it took over. That may be because the containers were usually in part shade areas.

I’ve never been a huge fan of potentilla, but I really liked the look of the new First Editions® Lemon Meringue™ potentilla from Twin Cities-based Bailey Nurseries. The blooms on this plant look like tiny, yellow roses and the foliage is neat. The plant grows 2 to 3 feet tall and wide, making it a good option for smaller landscapes. Potentilla is completely hardy to northern climates and virtually maintenance free. This looks like a great addition to potentilla options.

divine imptiensThe last plant I’d like to recommend is not new per-se, but is a recent introduction for those who love impatiens but are concerned about downy mildew on impatiens. Northern Gardener Plant to Pick columnist Debbie Lonnee recommended the Divine series of New Guinea impatiens in her column. Since my garden was on a tour and I have a lot of shady spots, I bought an entire flat of them to use to brighten up parts of the garden. They were a bit slow to get going, but once they took off they were gorgeous. (For the tour, I grew some of them in containers, which got them to a bigger size faster, then planted them on the edge of some of my tree, shrub or perennial beds.) While the small frosts we’ve had recently, have nipped some of the Divine impatiens, many are still going strong.

Getting Ready for Seed Starting

Looking at a forecast that includes several days of 60 degree weather, in March, in Minnesota — well, it’s hard not to be thinking about seed starting. But hold off — this too may pass and, in fact, I’m hoping it does. A very early spring can wreck havoc on Minnesota’s outdoor plants as we found out in 2012 when an unreasonably warm March caused fruit trees and other plants to start acting like it was spring only to get zapped by a nasty freeze in April.

I organize seeds by whether I'm starting them indoors or out and on which day.
I organize seeds by whether I’m starting them indoors or out and on which day.

So, while this weather is tempting, stay off the grass and out of your gardens to avoid compacting the thawing earth, and think about indoor seed starting instead. I’m getting ready to start seeds in the next couple of weeks. I’ve checked my light set up to make sure it’s still working and organized my seed box so I know when to start what. This year I’ll be starting a few more annual flowers than I have in the past. I find the home-started annuals do just as well as those I’ve bought as starts and there is a big savings on costs.

This is not a cosmos I started from seed, or grew at all, but isn't it pretty?
This is not a cosmos I started from seed, or grew at all, but isn’t it pretty?

Most of them can be started about the same time as many of your vegetables. Here’s a typical schedule for starting annuals. The “last frost” date in Minnesota is typically in early to mid-May, so I use May 15 to be on the safe side.

8-10 weeks before last frost: Baby’s breath, viola, vinca, alyssum

6-8 weeks before last frost: Snapdragons, ageratum, gomphrena

4-6 weeks before last frost: Celosia, cosmos, sunflower, marigolds, salvia

This year, I’ll be starting baby’s breath, violas, cosmos, sunflowers, marigolds and salvias, in addition to a fair number of vegetables.

What plants will you be starting from seed this year?

Final Exam for New Introductions

pw pots1I’m one of those lucky garden writers who gets sent plants to try out about a year before the plants are introduced to the public. This is fun for me because they’re free (thank you, Proven Winners and Sakata!) and because I get a chance to see what kinds of color trends and plant styles will be on the market next year.

For the plants, this is their final exam before graduation. They’ve been tested like crazy in greenhouses and growing ranges, but always under the care of horticulturists. Now, they must undergo testing by regular gardeners — avid gardeners, of course, but ones that have other jobs, families and the usual distractions from plant maintenance. Good luck to them all!

I got my Proven Winners plants first, so this post deals largely with them. The box included a mix of annuals and perennials, and I put most of them into containers. I especially like the container pictured above with this dark purple coral bells (Dolce® ‘Blackberry Ice’), and a new pink mini-petunia (Supertunia® ‘Flamingo’). I added a side-oats grama, a Minnesota native grass that will be part of my meadow planting. I love the textures of the three plants together and think the pink and purples complement each other.

pwpots2The package also included some new begonias (Surefire™ ‘Rose’), so I combined them with a red calibrachoa (Superbells® ‘Pomegranate Punch’) in a two matching lime green pots. I’m hoping these will do well in the sunny area in my front garden. I used the same combination, along with a dainty ‘Diamond Frost’ euphorbia in another container near the front entry.

Not all the new plants went into containers, however. A diminutive sedum was planted in the front garden, where it will echo the shapes and colors of my other sedums. A couple of new bright purple verbena (Superbena® ‘Violet Ice’) were planted in my Mom’s garden, where they will probably get better care than any of my plants. That lady definitely has a green thumb!

Finally, I have two plants I’m still figuring out where to put. One is a new goji berry—Sweet Lifeberry® (Lycium barbarum) which is said to grow 12 feet tall. I think I have a good spot in back for it, but any time you have a 12-footer, you’ve got to stop to think. The last one is a plant I’ve never heard of—Creme Fraiche™ deutzia. I like its variegated foliage and hope to find a nice spot where it can complement the plants around it. The Proven Winners website recommends it be planted near yellow-flowered perennials or annuals.

As the summer goes on, I’ll report from time to time on how my trial plants are doing — including a post on my Sakata plants.  Which are your favorite of the new plants introduced this year?

Best Container Plant for 2011

Supertunia 'Bordeaux' with sweet potato vine and mixed pansies

There’s no prize with this award, just my unending admiration for a plant that bloomed, bloomed, and bloomed again throughout the cool, hot, humid, slow-to-start, slow-to-end summer of 2011. And the winner is: Supertunia® Bordeaux petunia.

I bought several of these from Eco Gardens in Northfield back in May for my front porch pots, and almost from the moment they were planted until I took them out of the pots on Saturday, they performed beautifully. They grew but did not get leggy, and their blooms were lovely both from the street and up-close. They looked especially nice with two kinds of sweet potato vine: ‘Marguerite’ and ‘Blackie’. The lime green and deep burgundy contrasted beautifully with the violet to deep-purple blooms of Bordeaux.

I’ll be buying Bordeaux again next season. What plant was the star of your containers this year?
