"Fifty Shades of Gray" in the Cottage Garden



 

The ethereal and striking shades of grey is a rare and sought-after flower. There is a human tendency to desire things that are hard if not impossible to have. Years ago, the illusive white marigold was so sought-after Burpee offered a $10,000 prize to the first american gardener to first grow it. Mrs. Vonk produce a snow-white marigold in 1975 and won the $10,000 prize. 





Grey can be an elusive color in floral terms… not many (if any) flowers are grey but there are ways to achieve that hue with some clever use of foliage, flowers and plants. 
Luckily for us gardeners living at the desert Southwest with copious hours of solar radiation and minimal cloud cover, gray and silver leaved plants thrive well in our compost-poor, yet mineral sufficient soils. Low water and low maintenance will keep these lighter colored plants not just surviving, but thriving. 
And so, it goes with using plants with white, gray, or silvery foliage in shrub beds, flower borders, and any fashion of container. They can range from nearly pure white to gray, gray-green, and with a bluish cast, to a shiny silver hue, all with darker and lighter tones or patches of variegation.
Grey foliage plants all but glow at dusk and light up gloomy shade and dark corners – including indoors - but when used on their own, gray and silver plants can lead the eye while mellowing the landscape, taming intense colors, or serving as buffers between design changes. They also help bring out the best in brighter colors, which shine a bit more with the contrast, and continue to create interest when nearby flowers are finished or not yet in bloom. I think of the neutral gray color, as in real life, to include many shades of gray – dull gray to shiny silvery white, hues of blue-green and gray-green colored leaves. They come in all sizes from thin and tiny (Cerastium tomentosum, snow in summer), to large, flimsy (Salvia argentea, silver sage), tough and fleshy (Stachys byzantina, lambs ear) and thick succulent (Agave parryii, Parry's agave and Echinocereus reichenbachii albispinus, white spined lace cactus), both smooth and prickly. Regardless of the form and appearance, silver and gray leaved plants found in nature (as opposed to white, hybridized variations) can usually be relied upon to be more drought tolerant and sun adaptable than their green relations.



Gray, interspersed with green foliage plants, increases the interest of a bed or border, although all silver or gray gardens can be dull, gloomy and unappealing. Plants with gray and silver foliage pair exceptionally well with pastel and bold colors alike from their green leaved relations. Monet, in his garden at Giverny, was fond of the color combination silver, red and green and silver, red, green and pink. 



Rose breeders seem particularly interested in breeding a variety of a grey rose such as Earl Grey; Stainless Steel and Sterling Silver.   


Other choices in the grey color family are dusty miller and Artemisia which both are easy to grow, trouble-free, and readily available all season at garden centers. I have containers filled with gray and silvery Agaves, Sedums, Echeverias, Santolina, curry plant (Helichrysum), Mexican ghost plant (Graptopetalum) and several species of gray or silvery Sansevieria.  In addition to the dusty miller (Senecio) and Artemisia ‘Powis Castle’, flower beds brimming with all sorts of foliage and flowering plants are both spiced up and toned down with silver sage (Salvia argentea), oversized cardoon plants (Cynara), snow-in-the-summer (Cerastium), Russian sage (Perovskia), Giant Silver Mullein (Verbascum), Dianthus, and Texas sage (Leucophyllum). I also lay claim to a huge Silver Princess Eucalyptus tree in my small front yard.

Gray, interspersed with green foliage plants, increases the interest of a bed or border, although all silver or gray gardens can be dull, gloomy and unappealing. Following nature's cue is often a safe bet. Even in desert communities the combinations of green with the gray is common. Only in the more extreme environments, mainly in highly salty or sodic soil communities, does gray appear to overwhelm, at least with our green-trained vision.

Are "Safe" Insecticides-Pesticides Good to Use in Your Garden?











There is an alarming and discernible decline in the population of pollinator insects that make seeds and fruits magically appear on plants, shrubs and trees. While this decline is not news for those of us interested in gardening and farming, we need to educate everyone about the far-reaching effects a loss of our pollinators will have on everyday ramp up our efforts to reverse this trend.

Your garden is an ecosystem, and involves an intricate web of life, from the soil microbes underground to the birds in the trees. It’s easy to grab the spray bottle to kill off the dandelions and blow down the flies, kill foliage eating caterpillars but what are the knock-on effects?  Many of the insects we think of as a backyard nuisance often provide services we don’t see. For example, many native wasp and fly species (even blowflies!) are pollinators as adults. And as larvae, they control many of the insect pests we see on our plants, or decompose organic wastes. Small reptiles, like geckoes and skinks, mostly feed on small insects that annoy us, like mosquitoes and midges.  




Insecticides/Pesticides 
When you grab a bottle of insecticide/Pesticides to kill off that annoying scavenger you are disrupting the food chain in the ecosystem. Insects we think of as indispensable are a favorite food source for many beneficial insects. Aphids and scale insects produce a sugary substance called honeydew as they suck on plants, which is an important sugar source for some beneficial insects like wasps, bees, ants and hoverflies. 

Insecticides can kill beneficial insects, or affect them indirectly by disrupting their metabolism or reproductive cycles. Overuse of herbicides removes important food resources, like dandelions, that pollinators rely on if other flowers are scarce.

Pollinators
Native pollinators, especially bees, are a keystone species in most of our nation's diverse ecosystems. Nearly 70 percent of all flowering plants need pollinators to reproduce. More than a third of our food and beverage supply relies on the plants they pollinate.
Pollinators, like bees and butterflies, need nectar and pollen sources throughout the growing season. Diversify your native plantings so that you have different flower fragrances, shapes and colors throughout the spring and fall. Often native shrubs, flowers and trees reseed themselves thus becoming the most sustainable and, therefore, most available of plants.
Not only are our native bees in decline (did you know that there are roughly 4,000 species?), so is the European honeybee, introduced in the 1600s and now critically important to our nation's agricultural production. The honeybee condition described as Colony Collapse Disorder continues to be the subject of much research with no single culprit identified as cause. Disease is also striking our native bumblebees (there are nearly 50 species in North America!).


What's a plant lover to do?
Native plants are survivors. They are disease resistant and less susceptible to drought conditions, making them more able to offer up their pollen and nectar when other plants are succumbing to infection and rainless summer conditions. Reducing or eliminating your use of pesticides and herbicides will make a tremendous difference in the recovery of pollinator populations. Dusts and sprays are not picky and will leave an equally toxic coating on pollinators. Limiting synthetic chemical use is one of the easiest and cheapest ways to enhance wildlife in gardens. So, I recommend, forget the spray and hand pick the annoying pest off your plant and relocate it to another area of your garden so the ecosystem in your garden won’t be disrupted.
