I’m late, late, late with a post on new plants coming out this year. Sorry about that. It keeps slipping my mind because it’s still quite cold and rainy here in Minnesota even though we’re well into June now, so going to the garden center hasn’t been high on my list. I do think I’ll go this weekend, though, and here are some of the new things this year that I’m planning to try if I can find them.
Oso Happy® Smoothie Rose (Rosa Oso Happy Smoothie ‘Zlesak Poly3’ PPAF)
Bred by David Zlesak, a Minnesota-based plant breeder, hort professor and all around wonderful guy, Oso Happy Smoothie almost seems too good to be true. But it isn’t, and I know because I’m one of the lucky writers who got to test this Proven Winners introduction in my gardens last summer. Hardy, THORNLESS and resistant to black spot, this diminutive rose grows to 3 feet tall and offers up bright pink single blooms from June until frost. Mine still looked fantastic at Halloween, planted in a protected spot near the house. Sadly, the rabbits ate it over the winter and now I need a new one that I will definitely fence this fall. Full sun. Zones 4 – 9.
Brunnera ‘Sea Heart’ (Brunnera macrophylla ‘Sea Heart’)
Plants Nouveau is behind this pretty new brunnera, which their website touts as “Like ‘Jack Frost’, but on steroids’, which sounds creepy, honestly. But they go on to explain that in a side-by-side test with ‘Jack Frost’, ‘Sea Hart’ flowered longer and better handled the heat and humidity. Sounds good, and the pink and blue blooms look lovely, too. I’ll always make room for brunneras. Full sun to full shade. Zones 4 to 8.
Heuchera Little Cutie™ Series
Terra Nova Nurseries introduced its mini coral bells series, Little Cutie, exclusively last summer. So I’m calling these plants new in 2013 because they are now much more widely available. The series includes seven petite, new heucheras, all bred for their outstanding colors, including ‘Blondie’, ‘Coco’, ‘Frost’, Ginger Snap’, Peppermint’, ‘Sugar Berry’ and ‘Sweet Tart’. Drought-tolerant and easy going as long as they’re planted in well-drained soil, these Little Cutie coral bells look best when grown in rock gardens or spots where they won’t get lost among larger plants. They also make great container plants, providing you heel them in before winter. Full sun to part shade. Zones 4 to 9 (depending on the variety).
Hibiscus ‘Midnight Marvel’
I added hardy hibiscus to my gardens a few years back and they never fail to stop passersby who want to know, “What are those beautiful, exotic-looking plants?” ‘Midnight Marvel’ from Walters Gardens kicks things up a notch with this hibiscus, which grows to 48 inches tall and offers dark black-burgundy foliage with gorgeous red blooms that last from mid-summer to fall. Full sun. Zones 4 – 9.
Wisteria ‘Betty Matthews’ (Wisteria macrostachya ‘Betty Matthews’ Summer Cascade)
I stupidly bought a Japanese wisteria years ago that never blooms and will likely never, ever bloom in our climate. So I’m going to euthanize the poor thing in a couple of weeks and replace it with this new variety from Bailey Nursery. Touted as being fragrant and more reliably cold hardy than other wisterias, ‘Betty Mathews’ has showy, dark-lavender blooms that are said to appear on new growth in early June. Once the flowers fade, cool-looking seedpods form in late summer and last into winter. Heck, I’ll try it. Full sun. Zones 4 – 8.
Pros weigh in on the best plants and gardening practices for our changing climate.
Extreme Gardening, that’s the name of the reality TV show someone really ought to make about what it’s like to be a northern gardener. We’re already well known for our ability to cope with short growing seasons while making sensible, hardy plant choices and coping with dreadful-sounding issues like frost heave and snow mold. Now, climate trends indicate that we must add excessive heat, humidity, drought and torrential “rain events” to our list of things to think about before putting trowel to dirt. Surely all of that adds up to enough adversity, struggle and tears to make a successful show, right?
As you no doubt have noticed, our climate is changing. In January, the U.S. National Oceanic and Atmospheric Administration announced that 2012 was the world’s 10th warmest year since 1880. Closer to home, 2012 was the warmest on record for the United States and the third warmest for Minnesota. But increasing average temperatures are not the only climate trend affecting our region. According to University of Minnesota Climatologist Mark Seeley, the average number of days with a high dew point in also increasing, and we are also experiencing changes in the amount and type of rainfall we get.
Annual precipitation has increased over the last several decades and is expected to continue to do so. Heavy rain that sometimes leads to flooding is becoming more common. Yet between these events, we are experiencing long periods of drought. Complicating matters further is the rate at which changes are happening, Seeley says. Because it is possible temperatures may rise faster than we, or nature, can adapt.Read More»
It’s spring in Minnesota and that means male frogs and toads are out singing sweet songs to all the ladies. My husband Mike and I were fortunate enough to come upon a wetland filled with song the other day while on a walk with our dog, Lily. We recorded what we heard and posted it so you can enjoy it too.
A few weeks back I did a short presentation in Pine City, Minn., on how to build good, healthy soil, and a woman in the audience asked: “How do I know if the compost I’m using is safe?”
I’ve been wondering that same thing, I told her, explaining that I’ve been researching the topic so I have some answers, but many more questions, too. This prompted more people to weigh in on the subject, asking: Was it important to use organic compost, especially when growing edibles? How do you know that even organic compost is safe?
Does composted manure from conventional farmers contain pesticide and herbicide residue that could cause problems in their gardens? Should you have compost tested to find out what’s in it before you use it on food crops and, if so, where? And what about GMOs? Is it safe to use composted manure produced on conventional farms on which cows eat things like Monsanto’s genetically modified Roundup Ready corn and alfalfa?
Complex questions like these are difficult to answer definitively for a lot of reasons. Sometimes, there aren’t many studies, if any, on a particular topic. Or maybe there are numerous seemingly reputable studies, but many of them conflict with one another. For example, as a journalist who interviews people for a living, I can tell you that for every scientist I’ve talked to who dismisses the French study that came out last year linking a genetically-modified strain of maize to huge tumors in rats, I’ve got another scientist saying the study should be given serious consideration.Read More»
Most every commercial potting mix contains sphagnum peat moss because it’s a good, lightweight, organic amendment that improves drainage, as well as water retention and air circulation. The downside to peat moss is that it isn’t a sustainable resource. Peat moss is the decomposing remains of living sphagnum moss, and it is harvested at unsustainable rates from bogs in a manner than involves scraping off the top layer of the living moss to get to the saleable product below.
This process destroys centuries-old bogs, doing away with wildlife habitat, releasing C02 into the air, and eliminating wetlands that help prevent flooding. Because of this, conservationists and scientists all over the world have been pushing for limits and even bans on peat moss harvesting.
In Britain, for example, where peat is often burned for fuel, harvesting has become so intense that the government has set goals for phasing out peat for home gardening use by 2020. Professional growers will need to go peat free by 2030. For more information, check out the Royal Horticulture Society’s website: http://www.rhs.org.uk/Gardening/Sustainable-gardening/Peat-and-the-environment/More-about-peat.
Most of the peat used by the horticultural industry in the U.S. comes from Canada where talk of limits and bans is also heating up. So, whether you are concerned about the sustainability of peat of not, now seems like as good a time as any to explore some peat-free potting soil options.Read More»
People have been talking about straw bale gardening for years and, I admit, I haven’t really paid much attention. It’s not that I wasn’t curious about the idea. It just wasn’t on the top of my list of things to try until recently when I got the opportunity to talk with Joel Karsten about his new book Straw Bale Gardens: The Breakthrough Method for Growing Vegetables Anywhere, Earlier and with No Weeding.
Karsten isn’t just another gardener talking about straw bale gardening. He invented straw bale gardening. That’s right; he came up with the idea for a growing technique that has now become an international sensation. And it all started when he was a kid growing up on a farm right here in Minnesota.
Farmers, he told me, have no need for piles of wet, unruly straw. So when a bale would break open for one reason or another and get rained on, his family would push it up against the barn to break down over time. “I always noticed that those stacked up, broken bales would have the biggest, tallest weeds growing out of them, so I knew there was nutrition in there,” Karsten recalls, adding that he didn’t think much more about it until 15 years later.
By then, he had earned a bachelor’s degree in horticulture from the University of Minnesota, and he and his wife Patty had just bought a house in Roseville. After looking forward to gardening at their new home, they were disappointed when they realized that their whole lot consisted of little more than construction debris in which nothing was going to grow well. Then, Karsten remembered those straw bales. “And I thought, what if I just line those bales up and try growing vegetables in them as they decompose?” he recalls.Read More»
