Plant News You Can Use

A traditional apple like this Red Delicious might not fare as well in a warming climate.

A recent article in the New York Times caught my eye: Hot weather cherries, drought resistant melons and six other crops that are being developed or already in the market could change how we eat in a fast warming world. In the face of our erratic climate, floods and pests that farmers never used to worry about plant breeders are working to perfect varieties of fruit and vegetables that can thrive under these conditions. Solutions can come from research in molecular technology to mining the vast global collections of seeds that have been conserved for centuries. These new fruits and vegetables taste good, too. Here are just a few in the news.

In a warming climate, cherries are finding it harder to get enough chill hours during the winter and also handle hotter summers. Breeders have come up with the heart-shaped Cheery Cupid which handles these conditions and is also juicy and sweet. They will be available next season in North American markets.

Then there are two new melons – the Supermelon and Flavorific – with deeper root systems have been bred to handle drought my pulling more water from the soil. They can drink less. The melons are sweet, with dense flesh, and have just been made available to farmers.

If you like cauliflower there’s a new variety that won’t get sunburned in a warming climate. Now, farmers fold the leaves back over the white head or curd by hand about two weeks before harvest. It’s expensive and time consuming. Plant breeders developed the Destinica, a true white cauliflower. It’s already in supermarkets. Essentially, it doesn’t get sunburned and it’s easier on the soil because fewer workers walk the fields. The same developer has breed a white cabbage that requires less nitrogen and can thrive during prolonged dry periods.

Breeding a new apple takes time. A horticulturist at Washington State University, Kate Evans, says twenty years is typical. Cosmic Crisp, an apple developed to grow well in the heat now grows on 21 million trees in Washington State.

Another promising new apple is the Tutti, a light crisp red apple being tested throughout Europe. A New Zealand company developed it to help Spanish farmers struggling with hotter temperatures.

We all love avocados. A new, more environmentally friendly avocado has been 50 years in the making. The Luna, which is nutty, smooth and perhaps a bit sweeter than the Haas, was developed by breeders at the University of California, Riverside which houses one of the world’s largest collections of avocado genetic material. The new trees are slender, shorter and have a smaller footprint. They use less water and produce more fruit on less land. They are also easier to harvest which saves labor costs.

Enter the potato. Potatoes like a constant, moderate supply of water and prefer cool weather, but the climate is changing so fast that researchers recently warned that the potato industry is in trouble. Researchers at the University of Maine are looking to South America, where potato cultivation began around 8,000 B.C. and to heat tolerant varieties in the American South for genetic traits that can help spuds survive excessive heat and floods.

Researchers are also exploring how to battle new waves of pests and disease that come with hotter, wetter growing conditions. One strategy being studied is breeding plants with hairier leaves which make it harder to insects to move through crops.

These are just some of the vegetables and fruits in our future.

Plant Combinations that Inspire

Warm-toned combinations look great in the fall.

You know it when you see it. That combination of plants that cry out “we get along.” Because it’s fall already after a way-too-short summer, I’m drawn to grasses and warm toned flowering perennials. I’m thinking of ways that will have any garden bursting with interest for the next few months. Therse are strategies for combining plants that are adaptable to all types of garden conditions whether you live in the sun or the shade and will also look good in other seasons of the year.

A vignette is a small group of plants that make a pleasing scene because of their complementary and contrasting features. I have several lists of good plant combinations that I regularly refer to when designing a garden. I usually start with a strong foliage plant then add other plants that have interesting texture, form or color.

When you look at a garden that you admire it’s usually the dramatic form of one of the plants that draws you in. When you use a plant with a bold, architectural form it makes a statement. The spiky foliage of Cream Delight phormium alongside a Burgundy loropetalum would make a good combination. Or how about creating a vignette of Festival Burgundy cordyline with Annabelle hydrangea and Cream de Mint pittosporum?

During the next few months plants begin to show soft, fall colors. Combine the fading foliage of these plants with plants that complement each other. The reddish fall color or Oakleaf hydrangea along with the pinkish-tan color of their fading flowers looks wonderful when combined with Japanese Forest Grass as it turns pink before winter. Another complementary fall combination is Royal Purple Smoke Tree surrounded by a bed of Autumn Joy sedum.

Strong colors sometimes contrast instead of blend when plants change colors in the fall. I like to tone down a combination with silver foliage. An example of this would be a plant grouping of Evening Glow phormium, sedum Autumn Joy and Glacier Blue or Tasmanian Tiger euphorbia.

Another way to create a great plant combination is by blending textures. Coral Bark Japanese maple and Plum Passion nandina work well together. Cistus Sunset with Spanish lavender and rosemary is another good combination. I also like a large mass of Blue Oat Grass and Salmon salvia greggii planted together. Santa Barbara daisy goes well with Red Fountain Grass.

My list of potential plant combinations is pretty long as I’ve made notes over the years. Each garden has its own personality and growing conditions. A hot, dry garden might depend on a ground cover ceanothus along with lavender while a shadier garden might use natives like heuchera maxima, iris douglasiana, yerba buena and salvia spathacea. Whatever plants you choose, let them work together to make exciting vignettes in your garden.

In a garden that inspires you the plants should be ones that you love looking at and taking care of. Some of us like the look of dark green plants while others like grasses that move in the wind. Others are not fans of succulents. Whether you grow plants to feed the birds and attract wildlife or want a little bit of everything there’s a combination of plants that’s perfect for you and your garden.

How to Make a Garden your Own

Adding personal touches makes a garden your own.

The cry for help came from a new homeowner. She loves her lovely new home but feels everything in the garden is in the wrong place. She wishes to create “a haven for birds and bugs and give it a sense of life.” The plant palette here is far different from Tennessee where she’s from but she describes herself as enthusiastic and willing to learn. Boy, do I have lots of ideas for her.

Outdoor spaces are just more inviting if they feel like a real room with a ceiling, walls and attractive flooring. An arbor or pergola is a good way to provide a lid on your outdoor space. If you have natural trees in your garden they can shield you from the sky in some areas and open up other areas to passing clouds and sun. You can achieve a similar effect with groups of potted trees that shade your sitting area. Japanese maples, ornamental plums, cherries or crabapple are just a few of the trees that do well in pots. If you like to grow edibles plant a fig in a pot to provide some shade.

Creating an outdoor room with vines will make your yard feel cozy. They readily provide the walls to enclose a space. Views from one part of the garden may be partially open, framed by vines or blocked entirely. Shrubs can also be used to create garden rooms but vines form a thin living wall that is quickly established. Creating boundaries with vines also adds vertical design elements to an otherwise flat landscape. By adding walls and a ceiling to your garden, you’ll be able to enjoy another dimension in addition to more color and fragrance.

The sounds you hear while in the garden are part of the experience, too. The atmosphere just wouldn’t be the same without the sound of rustling grasses, wind chimes or birds splashing about in the bird bath or fountain. Auditory elements can even come from the sound of gravel crunching underfoot as you walk or the wind in the trees.

Texture in the garden refers to the overall visual texture of the plants. Large, bold foliage like Flowering Maple, Pride of Madeira, rhododendron, viburnum, oakleaf hydrangea or hosta make a large garden appear smaller. Soft, fine foliage will make the garden appear larger by giving it the allusion of more space. Examples of finely textured plants include ornamental grasses, Breath of Heaven, ferns and asters. You might use different textured plants in different parts of your garden to get the affect you like.

Create an interesting path experience with color & fragrance

Blur the garden’s boundaries to make it more interesting. You won’t be able to see the whole garden at one glance if you curve the path behind some shrubs, tall plants or sheer, see-through perennials. Leave some wild areas for the birds and bees to join you. Garden organically and mix in native plants wherever you can to keep the garden healthy.

Garden lighting is another easy way to add atmosphere to your garden. As inviting a space a garden might be during the day it becomes magical at night when lit. Solar lighting has come a long way. Walk your property and decide the most effective spots for lighting. Pathway lighting can illuminate the driveway, walkways and steps and mark the edges of areas like ponds and patios. Accent lighting can define a space and show off plantings, benches or illuminate a pergola. Spotlights direct the eye up into trees, show off garden art or accent a focal point.

Sound is important too. Ornamental grasses rustle in the wind or add a fountain with running water. An urn fountain with pebbles and plants at the base would be a simple choice. A drilled basalt column fountain or basalt dish fountain would look natural in the forest here.

Your sense of smell is important also to create atmosphere in the garden. In the spring the smell of ceanothus fills the air. Then the stargazer lilies start to bloom followed by lily-of-the-valley, daphne, flowering crabapple, carnation, iris, heliotrope, lavender, alyssum and a couple of roses. By enjoying the fragrance of both flowers and the foliage of salvia, lavender and breath of heaven as I walk the garden I’m able to add another dimension to the garden.

Creating atmosphere in the garden is the art of combining space, time and light to make a garden that reflects who we are. It’s different for every gardener. One person might like straight rows of vegetables while another scatters poppies and nasturtiums randomly. Whatever appeals to you it should be close to your heart and that’s the atmosphere in your garden that’s right for you.
