Long leafed Yellowwood

60113+Of the various specie of podocarpus, and as the name implies, the long leafed yellowwood, Podocarpus henkelii, has the longest leaves. They can get about six inches long, and hang elegantly from upwardly curving branches. This glossy evergreen foliage can be quite dense. It is dark green in full sun, and can be a slightly bluish in partial shade, particularly as new growth develops.

Mature trees have the potentially to get a bit taller than second story eaves, and nearly as broad, but are typically kept shorter. Most grow as big fluffy shrubbery or as informal hedges. Long leafed yellowwood can be pruned (but not shorn) into a handsome formal hedge, or even espaliered against a fence. It prefers somewhat regular watering and well drained soil. It might be unhappy in dense soil. Fertilizer can improve color and density if foliage gets distressed.

Peach

70726thumbJust like roses and camellias, the innocent peach, Prunus persica, has been developed into too many distinct cultivars to write about in just a few brief paragraphs. It had been in cultivation for thousands of years before arriving in North America. Peach is a classic summer fruit, but trees should be planted while dormant, preferably as bare root stock, about now, in the middle of winter.

Peaches certainly do not grow everywhere in North America. They need just enough chill to be reminded that it is winter; but too much chill too late in the season will ruin bloom. Too much late rain will rot developing fruit. Peaches are therefore right at home in chaparral climates of California, where freestone cultivars are grown for fresh fruit, and clingstone cultivars are grown for canning.

Healthy peach trees can get up to second story eaves, but if properly pruned, should be only half as tall. They should not get too wide either, since the weight of fruit can break limbs. Aggressive winter pruning keeps trees vigorous and resistant to disease. Orchard trees last less than twenty years, although home garden trees are often kept longer. Nectarines are just fuzzless peaches.

‘Red Star’ Atlantic Whitecedar

60106Is it red or white? Actually, it is neither. ‘Whitecedar’ is the common name for Chamaecyparis thyoides, which is a formidable coastal conifer from Maine to Mississippi. ‘Red Star’ is a much smaller garden variety. Its finely textured foliage is bluish green when it first emerges in spring, and can turn slightly purplish or bronzed gray if it gets cold enough in winter, but never turns red.

In more humid climates, ‘Red Star’ Atlantic whitecedar can eventually reach second story eaves, and can get half as broad. It rarely gets half as large locally, and can take quite a few years to do so. The slightly aromatic evergreen growth is densely conical, almost like a lumpy dwarf Alberta Spruce with an upwardly rounded underside. It can be a bit more sculptural if partially shaded.

Even without pruning, ‘Red Star’ Atlantic whitecedar is symmetrical enough for formal landscapes. Alternatively, it can add a bit of formality to relaxed landscapes. Although it is slow to provide privacy, it works nicely as an unshorn hedge. If somewhat crowded in a row, it grows taller faster. Shorn hedges lack natural form, but can recover their natural texture between shearing.

English Holly

90109We all know that holly is famous for holly berries, but in modern gardening, English holly, Ilex aquifolium, is appreciated, or despised, for its distinctively glossy but very prickly evergreen foliage. Like countless tiny thorns, the foliage is too prickly to handle for those who despise it. Those who appreciate it know there is no substitute for the elegantly polished sheen and handsome texture.

The lack of berries is due to a lack of pollinators. Most plants are female, so are capable of making berries. However, until recently, male plants were not even available in nurseries. Old formal hedges of female plants were typically accompanied by a few male plants in less refined parts of the same garden. Some newer hollies are grown with two plants of both genders in the same pot.

Most English holly is rich dark green, even though there are many exquisitely variegated cultivars. Some are variegated with silvery white or creamy white. A few are variegated with lemony yellow or gold. Variegated specimens tend to stay smaller. Unvariegated specimens can slowly grow into small shade trees with less prickly upper foliage, although most are kept less than ten feet tall.

Boulevard Cypress

51230Between New England and the Pacific Northwest, the boulevard cypress, Chamaecyparis pisifera ‘Cyano-viridis’, is classified as a small tree, even though it gets no bigger than large shrubbery. Locally, only very mature specimens reach the eaves, without getting much more than half as broad. Trunks and limbs remain concealed by fluffy evergreen foliage. Warm and dry air limit growth.

The handsome foliage is strikingly silvery blue, comparable to that of Colorado blue spruce or blue Arizona cypress, but with a surprisingly soft texture. It is really quite distinct from other evergreens, even other closely related chamaecyparis.

Boulevard cypress prefers cooler climates, so does well locally in light shade sheltered from wind. During warm weather, it can get roasted if too exposed. Although it does not require much water when mature, it is happiest if watered somewhat regularly.

Domingo Pine

90102The big name of this little pine takes some explaining. Domingo pine is a cultivator of an interspecific hybrid of two distinct specie, Eastern white pine, Pinus strobus, and Mexican white pine, Pinus ayacahuite. Until a better name in invented, it is known as Pinus strobus X ayacahuite ‘Domingo’. It is typically but incorrectly abbreviated as Pinus ‘Domingo’, or Pinus strobus ‘Domingo’.

Like many hybrids, Domingo pine got the best of both parents, and also stays compact enough for suburban gardens. Although not quite as soft and blue as Eastern white pine, its finely textured and dense pine needle foliage has a grayish sheen to it. Like the Mexican white pine, it does not need much water once established. It wants full sun exposure but is otherwise not demanding.

Young trees may seem to grow quickly, but growth slows significantly with maturity so that trees to not get much taller than second story eaves. Their typically conical form does not get much more than half as wide as tall. They look best where they have room to stay well branched from top to bottom. Because they are not very big, clearance pruning of lower limbs comprises their symmetry.

Coast Rosemary

51223Just like real rosemary, the coast rosemary can either be a low ground cover or a dense shrub. Lower cultivars can get nearly five feet wide without getting much more than a foot high. Shrubby types can get nearly six feet tall without getting much wider. Shrubby types are more popular than ground cover types, and are often pruned so that they do not get too broad.

The tiny leaves of coast rosemary are silvery or grayish green, and can be variegated. Small white or very pale lavender flowers bloom sporadically throughout the year, and can be profuse in spring. Established plants do not need much water, but are probably happiest if watered somewhat regularly through summer. Shade subdues silvery foliar color and inhibits bloom.

Shrubby coast rosemary makes a delightful low hedge. It can be shorn like any other formal hedge, but is best where it has space to develop naturally. If space is limited, but not ‘too’ limited, a coast rosemary hedge can be aggressively shorn once annually at the end of winter, and then allowed to grow wild for the rest of the year.

English Hawthorn

81226The first specie to be imported to North America from Europe were utilitarian plants that produced fruits, vegetables or other horticultural products. English hawthorn, Crataegus laevigata, was likely one of the first ornamental specie to be imported merely because those who were familiar with it appreciated the delightful white spring bloom and the rich red berries in autumn and winter.

The biggest trees should not get much higher than second story eaves, but the handsomely coarse texture of the bark, furrowed trunks and almost oaken foliar texture make these relatively small trees seem rather grand. Unfortunately, the stems, particularly the most vigorous, are quite thorny. The lobed leaves are about one or two inches long and wide, and might turn orange in autumn.

The trusses of small white flowers that bloom in spring resemble those of pear, and like pear bloom, produce a musky fragrance that some might find objectionable. Some cultivars and hybrids bloom with less fragrant pink, double pink or double red flowers. Some produce orange or yellow berries. If birds to not take them too quickly, the pendulous trusses of berries can last into winter.

‘Little John’ Bottlebrush

P81214Where it has space to grow, classic lemon bottlebrush that was so popular in the 1960’s is still a practical and resilient large shrub, and is happy to bloom with bright scarlet flowers as long as the weather is warm. It is resistant to most diseases and pests, and once established, survives on annual rainfall. Its main problem is that it simply gets too big for many situations.

Dwarf bottlebrush, Callistemon ‘Little John’, is more often a better fit, although it has a very different personality. It is short and dense, and spreads more laterally than upright. Mature plants are only about three or four feet tall, and maybe twice as wide. The smaller leaves are somewhat grayish. The distinctive bottlebrush flowers are a slightly darker shade of purplish red.

Even though established plants do not need much water at all, regular (but not necessarily generous) watering promotes bloom and growth. However, excessive watering can be lethal. Full sun exposure is best. A bit of light shade should be no problem. Dwarf bottlebrush makes a nice low informal (unshorn) hedge. Flowers attract bees and hummingbirds.

Sasanqua Camellia

81219Some might say it blooms very late. Others might say it blooms very early. Regardless, sasanqua camellia, Camellia sasanqua, blooms in autumn or early winter when not much else is blooming. The abundant two inch wide flowers can be pale pink, rich pink, white or red, all with prominent yellow stamens. Some are fluffy with many petals. Others have only a few. Alas, fragrance is rare.

Each cultivar of sasanqua camellia has a distinct personality. Some are strictly upright, and can eventually get somewhat higher than downstairs eaves. Others are too limber to stand upright on their own; so they grow as low mounds, or espaliered onto trellises. With proper pruning that does not compromise bloom too much, some can be pruned as hedges, or as foundations plantings.

Sasanqua camellia has been in cultivation for many centuries. Prior to breeding for bloom in the past few centuries, it was grown for tea and tea seed oil, which is extracted from the seeds. This oil is used for culinary purposes and cosmetics. The finely serrate elliptical ‘tea’ leaves are about one to two and a half inches long. The glossy evergreen foliage is appealing throughout the year.
