Crape Myrtle

Crepe myrtle has notably complaisant roots.

The popularity of crape myrtle, Lagerstroemia indica, is mostly justifiable. It is a compact tree, so is proportionate to small urban gardens. Its roots are very complaisant, so should not displace pavement. It blooms spectacularly for summer, and then develops fiery foliar color for autumn. Its only problem is that it is so popular that it has become too common.

The largest cultivars of crape myrtle do not grow much taller than twenty feet. Therefore, they are appropriate for utility easements with high voltage cables. Because of their very docile roots, they are popular as street trees. Although, they do not grow wide enough to provide much shade. Street trees should have single trunks. Others can have multiples.

Floral color is white, pink, red or mauve. Bloom can be very profuse and billowy. Autumn foliar color is bright yellow, orange and red before defoliation. The smooth bark is nicely mottled. Aggressive dormant pruning for winter delays bloom, but promotes bigger floral trusses. Crape myrtle enjoys warmth and full sun exposure. It does not need much water, once established.

Flowering Cherry

Flowering cherries bloom for early spring.

Flowering cherries are a complicated group of many distinct hybrids, of several species. Japanese cherry, Prunus serrulata, is the most common ancestor of almost all of them. It is a relatively small deciduous tree that does not get much more than twenty five feet tall. The wild species produces unpalatable fruit, but its many hybrids are generally fruitless.

Most flowering cherries exhibit splendid autumn foliar color, with yellow, orange and red. Weeping cultivars develop strikingly pendulous form. Birch bark cherry exhibits distinctly smooth and chestnut brown bark, with broad lenticels. Weeping cultivars are sometimes grafted onto birch bark cherry trunks. This combines pendulous form with smooth trunks.

The primary allure of flowering cherries, though, is their profusions of early spring bloom. Floral color ranges from bright white to rosy pink, although most cultivars are pastel pink. Flowers can be delicately single or billowy double. Some cultivars bloom slightly earlier or later than others, but all bloom quite early. Their blooming stems are pretty cut flowers.

Flowering Apricot

Flowering apricot blooms almost too early.

Flowering cherries are not necessarily the first of the flowering trees to bloom. Flowering apricot, Prunus mume, is even earlier than all but the winter flowering cherry. Many have bloomed already, and as early as a month ago. The latest will bloom soon. Their flowers are more resilient to weather than those of flowering cherry. However, they bloom briefly.

Although generally fruitless, a few cultivars produce fruit for pickling, as umeboshi. Such fruit, without pickling, is rather unpalatable. Some cultivars of flowering apricot are useful as understock for related trees. Actually, some local flowering apricot trees grew from the roots of other flowering plums. New trees are very rarely available from nurseries locally.

Mature flowering apricot trees are ten to nearly twenty feet tall and almost as broad. They bloom before they foliate. Abundant bloom on big trees can be mildly fragrant. Individual flowers are about an inch wide. They are pastel pink, but can be white or deep rosy pink. Blooming stems can be exquisite as cut flowers, although they may not last for very long. Such stems are a traditional component of ikebana.

Purple Leaf Plum

Spring bloom is spectacular prior to foliation.

There are actually several different purple leaf plums, Prunus cerasifera, to provide colorful white or pink bloom sometime between the middle of winter and the middle of spring, followed by colorful bronzy or purplish foliage through summer. Some also provide good fruit, which can unfortunately be messy if it is not harvested. Most stay quite compact, less than twenty feet tall and broad, so are proportionate to small garden spaces. ‘Hollywood’ is the largest, but rarely gets more than thirty feet tall, and not quite as broad. Prunus X cistena does not get much more than six feet tall and broad.

Because each cultivar has a distinct personality, it is important to match trees when adding or replacing trees in a grove. The fruitful ‘Atropurpurea’ has single white flowers in spring, followed by bronzy red new growth that turns purplish in summer and reddish brown in autumn. ‘Krauter Vesuvius’ has single pale pink flowers and the darkest foliage, but lacks fruit. ‘Thundercloud’ has similar or paler flowers, lighter or more bronzy foliage, and sometimes produces tangy red fruit about an inch wide. Prunus X blireiana (illustrated) fades to bronzy green by summer, but has handsome branch structure and double pink flowers that are slightly fragrant. Unlike plums that are grown for larger and more abundant fruit, purple leaf plums do not need much pruning.

Flowering Crabapple

Flowering crabapple is more colorful than crabapples that are grown more for fruit.

This picture resembles flowering cherry, but is actually a flowering crabapple, Malus spp.. Both provide impressively abundant spring bloom before foliation in spring. Both may have single, semidouble or double flowers in various shades ranging from white to rich pink. Some flowering crabapples though have nearly red flowers. Flowering crabapples get slightly larger, more than twenty feet tall and broad; but some stay as short as five feet, and others get taller than thirty feet! Some have bronzy or purplish foliage through summer. The half inch to nearly two inch wide yellow, orange or red fruit can be colorful into autumn, and some makes good jelly; but it can also be messy. The main advantage of flowering crabapples is that they are somewhat less susceptible to rot than flowering cherries are in dense slowly draining soil.

Flowering Cherry

Flowering cherry is the fruitless counterpart of fruiting cherry.

Like camellias and chrysanthemums, the many different varieties of flowering cherries, Prunus spp., have been developed by horticulturists in Japan for centuries. There are now almost too many to choose from. Most stay less than about twenty feet tall and broad, so are proportionate to compact gardens. A few stay even smaller. The classic Yoshino flowering cherry can get somewhat larger. Weeping cherries have pendulous branches. Columnar types are noticeably taller than wide, at least while young. Some flowering cherries have remarkable fall color.

Despite my preference for cherry trees that produce cherries, I can not deny that the spring bloom of the innately non-fruiting flowering cherries is spectacular! Most bloom before any foliage develops. Their flowers can be single, semidouble or double, in various shades of white or pink, including rich rosy pink. They can not be very messy without fruit. Unfortunately though, flowering cherry trees are susceptible to rot in the endemically dense soil, so should not be watered too much.
