Holding winter at bay, the Danish Way

Haveselskabets Have, Horticultural Society Garden

Ordinarily, December isn’t the month you’d consider for visiting gardens, but the curious gardener welcomes any opportunity to observe new plants and planting schemes, even in winter. Earlier this month, Chris and I had the good fortune, along with dear friends Elin, Lasse, Nicole and Marc, to visit Copenhagen, and we had to make time for checking out the various public gardens.

There were many surprises: most importantly, the climate.This Scandinavian country has milder winters than we have here in Massachusetts, with the average low of 32F, or 0C.  Yes, this means they can grow zone 8b plants like Melianthus. Summers are cool, with average temperatures of 67F (17C).  Temperatures like this allow for plants which dislike summer heat, such as Mountain Ash (Sorbus) to flourish. Being at a higher latitude means that winter day length is short, and the reverse is true in summer. This has a big effect on plant growth, and there are far less dramatic day to day temperature fluctuations due to the maritime climate.

Danes are eager to be outdoors year round, no doubt to absorb as much natural light as possible, and design their gardens and landscapes to have strong winter interest. Evergreens, fruit-bearing trees and shrubs, grasses and seed heads add structure, color and form. One thing that struck us was the balance of formal and naturalistic plantings working together. Trees are routinely pollarded. Boxwood is commonly sheared into geometric forms. Clipped plantings are mixed with billowing shrubs, masses of grasses and herbaceous plants. While I would not feel at home in a rigidly formal garden this blending of treatments was fun and unexpected.

Garden structures and hardscape play an important role in Danish gardens. Planting beds tend to have squared off geometry rather than wavy lines. Sculpture plus a strong role. Outdoor seating its always considered, in both open or intimate settings. In this often overcast climate, brick buildings are often stained in shades of orange or gold to brighten the otherwise neutral grays and browns of winter.

Seasonal containers included plantings of Christmas Rose, (Helleborus niger), Heath, (Erica), Boxwood (Buxus) and Ivy (Hedera), accented with cut branches of Winterberry and Evergreens. Popup street vendors were selling potted winter interest plants including Skimmia, Hellebores, forced hyacinth, and Amaryllis along with branches and boughs of holly. A particularly magical floral shop Tage-Anderssen, had exquisite window displays, showcasing carefully crafted centerpieces using plant based materials.

Danish interior design is world renown, celebrating geometry and simple lines. But what this gardener couldn’t help to notice were the many plant based accents, in the form of cut flowers, forced bulbs or potted succulents, used to soften and add warmth to living spaces. During the short days of winter, the Danes decorate interior spaces with white lights and candles, a particularly “hygge” thing to do.

winter solstice greetings!

As we head approach the solstice, with weeks of colder weather before us, I’ll hold onto my Danish experience. Today I brought in cut  branches of holly and boxwood, and will illuminate the darkness with candles and strings of lights, to drive the cold winter away.

Tips for Fall Containers

Black Mondo Grass with hardy succulents

Are your summer planters in need of a fall makeover?  Are you thinking you would rather invest in perennials than toss away non hardy plants at season’s end? There are many fall-flavored hardy plants which will provide you with texture, form and long lasting colorful foliage. Plants to consider include Ornamental Grasses, Ophiopogon, Hardy Succulents, Heuchera, Euphorbias, Ivies, Dwarf Evergreens, to name a few.

Here’s a few tips.

1. To achieve a fuller affect, use more plants than you would in the spring or summer.  We don’t want to think about this now, but the days have been getting shorter, nights cooler, and plant growth is slowing down or ceasing.

2. Select plants that have a variety of tones that will contrast and set off each other, (think amber Heuchera and black Ophiopogon).

3. Remember a pot of mums looks fresh for 3-4 weeks at most, then the show is over. Showy foliage will carry on and on.

4. Note that the fall foliage on evergreen Sempervivum (hens and chicks), Sedum ‘Angelina’, and Sedum album cultivars change and develop more dramatic color once the temperatures stay cool.

5. If you must have flower power, consider long and late blooming Salvia, Cuphea, or fall pansies.

6. When a night time temperature drop is forecasted, have light blankets, large pots or even an empty trash barrel handy to cover your container and protect the plantings from frost.

7. As November passes, he time will come to  disassemble your planter. Tuck your hardy plants in a nursery bed or empty space in your vegetable garden plot to hold them over until next spring.
