Planting the White Garden

Planting the White Garden–A How-To

According to colour theory, white conveys purity, cleanliness, safety, wholeness, perfection. That’s not my own idea, you’ll find it in just about every resource about colour. (Including this interesting one about “white in ‘Breaking Bad'”!) White will glow in low light situations, like your shade garden, or in the evening.

It also conveys a sense of restfulness, so while other gardens encourage you to get in there and play, or work, or DO something, the white garden wants you to sit, read a book, have a glass of wine, REST.

A disclaimer to start with: none of the  pictures included here are my own, since I don’t have a white garden myself.

Structure

I’ve said this often before: layer your garden with trees, shrubs, tallish perennials (or annuals for that matter) and low growing ground covers. (It shouldn’t look like stadium seating– remember, you’re viewing the garden from lots of different angles.) The white garden is no exception, in fact will need layering even more.

Vines will give a variant on the taller shrubs. Evergreen Clematis armandii blooms in late winter and will climb as high as there is something to climb on. Ditto for climbing Hydrangea petiolaris. The latter needs something REALLY strong to hold it. Like a brick chimney, or a tree. I recently designed a garden with Hydrangea petiolaris climbing a very large, very dead old cedar that the owners were unwilling to pay exhorbitantly to have removed.

Texture

Any garden needs a combination of textures. Spikey (Acanthus, Yucca, New Zealand Flax), soft and fluffy (Baby’s Breath–Gypsophila, wonderfully fragrant Alyssum), grassy (Miscanthus sinensis, as below, or Mexican Feather Grass–Stipa tenuissima), bold–large leaf Hosta, Rodgersia, Rhodo.

Two plants next to each other that have similar leaf shape sort of meld into one, even if the leaf colour is different (unless they’re very different, like the dark copper of Ninebark (Physocarpus), and the gold/chartreuse of  Spirea). But put a bold leaf Hosta next to an ornamental grass or Baby’s Breath or the Spirea, and you’ve got the beginnings of a dynamite combination.

Sequential Blooming

Choose plants that will bloom at different times in the year. Of course, starting with spring bulbs–snowdrops, then crocuses (croci?), tulips, alliums. Then move on to early perennials like Iberis sempervirens (perennial Candytuft), white Columbine (Aquilega), white creeping Phlox subulata. White flowering shrubs can take the place of one or another season of whites: Azalea blooms mid-spring, Philadelphus and Deutzia mid-late spring, Hydrangea early to mid summer. And don’t forget trees–Cornus (Dogwood) ‘Eddie’s White Wonder’ in late spring, Oxydendron (Sourwood) in late summer.  I don’t have to list every possibility–you’ll have the idea now.

The garden above, almost completely bordered by hydrangea, will look a little tatty in late summer/fall as the white blooms turn to brown. A white garden might require a little more diligent deadheading than a mixed colour garden, simply because the faded white blooms sometimes look less attractive that other colours.

Style–Formal or Chaotic?

One of the things you usually see in white gardens is a fairly formal style. It doesn’t have to be that way, but white and green lends itself to a formal feel. White roses will complement the formal style–as long as it is highly disease-resistant. Check rose suppliers in your own area for roses that will work for you. The Sissinghurst White Garden below started in the 30’s as a white rose garden.

If formal isn’t your cup of tea, but you still want soothing effect of the white palette, a simple solution is to just have non-formal shaped beds. Formal beds would be symmetrical, very geometric, usually square, and often surrounded by boxwood or another clipped hedge. Changing up any of those elements would “casualize” the aesthetic.

Unless your house is very linear (think Frank Lloyd Wright), square, or “Arts and Crafts” style, most other houses, with or without curvy lines in the roof, porch or other, will easily accept curved planting beds. That feature itself will instantly eliminate that rigid formality. No straight lines means the borders will vary in width and depth, which means they’ll also vary in how the plants–even the same plants as in a formal design–are located.

Surprise

You might consider planting some surprise colour spots in your white garden. Nothing too striking, no red geraniums or orange daylilies (Hemerocallis), and of course, no wide swathes of colour. But maybe a few purple alliums in spring, some pink Astilbe, the very airy blue of Brunnera, maybe gold Rudbeckia…
