Shrubs and Perennials -
 White Favorites


Swath of Shasta Daisies, Hesperus in background

Joan Shaw

Thoughts at Fall
In late October here at the farm, when the temperature plunges into the twenties at night and the grass is hidden in a blanket of discarded leaves and the trees and shrubs are stark looking and bare and most of the perennials, like the swath of Shasta Daisies shown above in midsummer, have turned into a swath of dead stalks, it's comforting to remember that next spring will bring life again, often exuberant life.

There is one variety of shrub out there that's still hanging on to life, however – the Hydrangea 'Annabelle' –  and it's one of my favorite whites, not only through the summer, but on through the fall and winter.

Below – with our gardener of three years, Shirlaine Zeyer – is one specimen of this long border of shrubs which was Hydrangea, Annabelle, with gardener, Shirlaine Zeyer then, in midsummer, just starting to come into full bloom. These flower heads can grow from the size shown to up to twelve inches across. From the dazzling white of summer, these enormous heads fade to green as fall approaches, then fade further to brown as the winter snows begin. In early spring, we cut their stems down to within six or eight inches of the ground. Shoots begin breaking through shortly thereafter, and off they go again, bigger and better than ever.

White Roses

The biggest garden excitement here, though, is the June into July rose bloom. We have some three hundred varieties of roses in the garden, the largest number of them antiques that bloom only once in early summer – a bloom, however, that is truly spectacular. In addition, we have a number of Austin's English roses, some twenty Old Garden Roses, several albas, rugosas, moss roses, some newer varieties of the English Rose type, and many modern shrub roses and groundcover roses, all of which bloom periodically throughout the summer.

Of the groundcover class, one of the most rewarding is the planting of the Rosa Meidiland 'Alba' groundcoverBlossoms of the Meidland Alba Groundcover Rose roses that fills a ten by fifteen foot spot in front of the parlor windows and spills over the brick walks surrounding it. After being pruned down to within five or ten inches of the ground in early spring, these plants burst into new growth as soon as the weather warms, sending up long, flexible canes that arch into a bed some three feet high. By the end of June, the canes are literally smothered in a breathtaking show of dainty white flowers (shown at right), each measuring an inch across. These lovely blooms stay fresh and white for many weeks. In our northern Utah climate, this first show is followed by several more flushes, each slightly less heavy than the one before, but continuing through October and, at times, into early November.

White Columbine
Also in early summer, we have a nice show of Columbine  (Aquiligea species) of various  types, among which – I was delighted to discover – appeared spontaneously a number of whites and near-whites (one plant is shown at above left). Rocky Mountain Columbine (Aquilegea  caerulea) is the state flower of Colorado with big, startingly blue and white flowers. It's hardy into Zone 3, and happiest in the cooler, higher areas of the west. The first few we planted, when finally established, hybridized into lovely darker blues and even pinks, as well as the surprising whites. They seem to be happiest here under high shade trees, nodding shyly from behind trunks and the limbs of shrubs, though they can take a good bit of sun here at 4500 feet.

Last spring we included with them several plants of the 'Swallowtail' Columbine, a type propagated by David Salman of High Country Gardens. David used seed supplied by Sally and Tim Walker of Tucson, who found a colony of them in an isolated Arizona canyon.  I'm looking forward to watching them grow and multiply. This type of Columbine is zoned at 5-10 by High Country Gardens, and we're on the border of five and four, but I've planted them in a south-facing bed under some tall trees, so I'm sure they'll thrive.  Whether they will hybridize with the other types and wipe out our whites remains to be seen.

A Kind of Namesake

Another special white for me is the Daylily 'Joan Senior,' two plants of Daylily Joan Senior which were given to me for my birthday by my daughter, Melanie. Shown here at right during their second year are some of the big, creamy white blossoms that kept coming and coming for something like a month.
 
 

Another Gift
Below is a surprise offering for us, supplied by our cohort of birds roosting (and digesting) above a moist bit of ground next to a tall Marshall Seedless Ash –
Elderberry bush, just starting to bloom an Elderberry. We first noticed it a couple of years ago, growing up in the middle of a pink Bridal Wreath, and gave up trying to get it out. Now it resembles a small, many-trunked  tree and had a lovely crop of white, plate-sized flower heads this summer and last. So far, the Bridal Wreath seems to be holding up under the onslaught. Indeed, it seems to be thriving around the Elderberry's legs.

At this point, in early Semptember, the Elderberry is bent down with flat plates of berries which I'm not much interested in making into (more!) jam. Perhaps next year I'll try it, though Alan, my husband, is lobbying for Elderberry Wine. Birds are said to be fond of Elderberries, but so far, they appeared to have ignored ours.

We've come to the conclusion that the plant is most likely the common American Elder, Sambucus canadensis . We have common American Elder growing in the canyons here, so the birds could have brought it down from there. It could also be one of the improved cultivars of American Elder, planted perhaps by a nearby neighbor. Cultivars of American Elder are offered by many nurseries.

Meanwhile, the nights, needless to say (it's September, after all), are getting longer, and also much, much cooler. Soon the Elderberry, many of the roses, and the 'Annabelle' Hydrangea border will be showing orange and yellow leaves. Different seasons, as we all know only too well, bring different colors.

And Roses:

The Companion to Roses - a fascinating source book for both botanical information and the lore of legends; it's one of my favorite reference works on rose culture and history
