10 New Vegetables and Herbs for Your Garden This Spring
By Brian Barth
Looking to spice it up this year in the old vegetable patch?
Plant breeders are always rolling out new varieties and reviving forgotten heirlooms that offer tantalizing tastes. Here are a few to consider.
1. Habanada Pepper
Row 7 Seed Company, the new seed supplier founded by chef Dan Barber of Blue Hill Stone Barns fame, has a growing selection of never-before-seen vegetable varieties, including this twist on a famously hot pepper. It has habanero flavor without all the heat. Get it? "Nada" of the "haba"?
2. Georgia Cabbage Collards
This low-growing collard forms loose heads with a cabbage-like flavor. An old-fashioned hybrid that was likely once grown throughout the South, this variety was nearly lost until a man named Bobby Prevatte, who inherited seeds from his grandparents, brought it to the attention of botanists. It's now available from Southern Exposure Seed Exchange.
3. Mouse Melon
While it may look like a watermelon that has been shrunk down to the size of a grape, this traditional Mexican vegetable is more closely related to cucumbers. New to North American palates, it's suddenly a hot item at specialty seed companies. The flavor is cucumber-like but with a delightful bite — it's often described as a cucumber that's already been pickled.
4. Ground Cherry
This unique crop looks like a cherry tomato but comes wrapped in a papery husk like a tomatillo. A relative of both vegetables, the ground cherry has a flavor that's a cross between the two: sweet and tomatoey, with a piquant aftertaste. As a bonus, it's not susceptible to the myriad pests and diseases that plague tomato plants.
Hailing from the high Andes, this ancient vegetable has recently found its way onto American plates. It's the tuberous root of the South American sunflower, which grows readily in North American soils. Raw yacón has a crunchy texture, with a flavor somewhere between celery and green apples. It's often added to salads, but it can also be cooked like a sweet potato.
6. Honeynut Squash
Another recent invention of the folks at Row 7 Seed Company, this is, essentially, a miniaturized version of butternut squash. The idea behind the company is to develop new vegetables bred specifically with chef-level culinary attributes. Honeynut squash, which has quickly become the darling of foodie circles, is Row 7's first smashing success. It concentrates all the flavor of a full-size butternut squash into a smaller, more potent package.
7. Tree Collards
These purplish-green collards grow on spindly stalks up to 10 feet tall. The flavor is sweeter and nuttier than standard collards. Even more impressive is their perennial nature: Unlike annual vegetables, tree collards produce year after year without replanting. Unfortunately, they only do so in mild-winter regions (prolonged temperatures below 20 degrees Fahrenheit will kill the plants). The good news is that you can grow them in a pot and cut the stalks down to a reasonable size before you bring them indoors for winter.
8. African Blue Basil
Speaking of perennial plants, here is a rare perennial basil, though it, too, dies when the cold weather arrives unless you bring it indoors. African blue basil isn't blue, but it is beautiful, with purple-tinged foliage and flowers. It grows into a compact, rounded shrub that looks more at home in a flower border than a vegetable garden.
9. Roman Camomile
German camomile — the kind that's typically brewed for tea — grows as a spindly, weed-like plant. Roman camomile — its distant cousin — grows as a flat green mat, about three inches tall, that tolerates foot traffic and can be used as an herbal lawn. A cold-hardy perennial, it has a similar flavor and fragrance to German camomile (an annual) but is much more concentrated. Use it as an ingredient in sweet iced tea, or simply sprawl out on the plant for an aromatherapy session.
10. Lavender Mint
Plant breeders are always coming up with new varieties of mint — a plant that is unusually amenable to genetic tinkering (we're talking old-fashioned breeding here, not genetic engineering). There's chocolate mint, pineapple mint and lemon mint, among many others. Now, there is also lavender mint. With two of the world's most popular herbs combined into one, what's not to like?

More long-finned pilot whales were found stranded today on beaches in Tasmania, Australia. About 500 whales have become stranded, including at least 380 that have died, the AP reported. It is the largest mass stranding in Australia's recorded history.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.
Sweden is a world leader in renewable energy consumption. Swedish Institute/World Bank
Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Scaling Up<p>A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, <a href="https://www.eonenergy.com/blog/2019/February/sweden-smart-city" target="_blank">has scaled up the smart grid principle</a>. Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
