Everyone knows that flowers provide color in the garden, particularly through spring and summer. As blooms become less abundant in autumn, fall color of deciduous plants and trees becomes more prominent. After most plants are finished blooming, and most of the fall color is gone, the garden may seem relatively bleak for winter. Only evergreen foliage remains. This is when plants that exhibit colorful bark or bare twigs really get noticed.
Various types of birch trees exhibit striking white bark all year. While the trees are bare in winter, the bark becomes even more prominent, particularly against a backdrop of evergreen trees. English walnut trees are not as striking, but are more sculptural. Fig trees (fruiting types) are more gray than white, so are more reliant on a backdrop of rich evergreen foliage or a darkly painted wall for contrast; but they grow fast enough to become interesting sculptural specimens within a few years.
Bright white or light gray bark are certainly no substitute for the colors of flowers or foliage, but are striking nonetheless. They exploit the starkness of winter, and the sculptural nature of bare trunks and limbs.
Even without the sculptural structure of birch, walnut or fig trees, the more colorful twiggy growth of coral bark Japanese maple and osier dogwood trees can be quite an advantage in a stark winter landscape. As the name implies, coral bark Japanese maple has pinkish orange twigs. Osier dogwood can be ruddy brown, brownish orange or pale yellow. Frost improves color.
Unlike other Japanese maples that get pruned only lightly to enhance their form, coral bark Japanese maple can get pruned rather harshly just prior to spring growth in order to promote an abundance of the twiggy growth that is so colorful in winter. Osier dogwoods can get pruned down almost to the ground at the end of winter to eliminate tired older stems and promote colorful new stems for the following winter. They lack the colorful bloom that flowering dogwoods provide; so it is no bother that such harsh pruning prevents them from blooming.
Like trees with white or gray stems, coral bark Japanese maples and osier dogwoods are more striking against a backdrop of rich green foliage. Because winters are so mild here, they should be located where they will be most exposed to chill.
Now, before I commence with my rant and long list of problems with this picture, I should mention that this seemingly abused rose tree does seem to be appreciated. All the roses in this landscape seem to be very healthy, and they bloom constantly between spring and autumn. Their performance suggests that they are regularly fertilized and deadheaded.
There is much more to the landscapes at work that I wrote about earlier this morning at 
Or . . . a close encounter of the third kind. Let’s just go with the former rather than the latter.
Many arborists mark certain lengths on their pole saws and pole pruners. When stood upright, these marks designate the standard heights for minimal clearance pruning. Not so many need to mark the height of minimal clearance for walkways, since they will prune away anything that is within reasonable reach with hand tools from the ground. The minimal clearance above parking spaces is not so easy to guess at, so is more likely to be marked on poles. So is the minimal clearance over roadways, where the lowest limbs must be high enough to be out of the way of campers and freight trucks.
