Persimmon

Persimmons ripen as their leaves fall.

It lacks the spectacular spring bloom of the other deciduous fruit trees, but compensates. Persimmon, Diospyros kaki, performs double duty with fall color. Its autumn foliar color is impressively fiery orange. Then, it defoliates to reveal plump, abundant and comparably fiery orange fruit. So, it is spectacular with both autumn foliar color and autumn fruit color.

Persimmon trees are tempting. Some cultivars can grow twenty feet tall to become small or even mid sized shade trees. However, if they do so, much of their overly abundant fruit is unreachable. Aggressive and strategic pruning limits their production with most of their fruit in reach. Although undemanding otherwise, this major dormant pruning is important.

Persimmons are self fruitful without a pollinator. However, they supposedly provide more fruit of better quality with another cultivar. Fruit is unfortunately inedible before thoroughly ripe, but then all ripens simultaneously. That is an incentive to share with neighbors and friends. With a bit of effort, fruit is conducive to drying and freezing, although not canning. Ripe fruit is very perishable.

Candelabra Tree

Candelabra tree resembles cacti, but is not related.

The weirdly sculptural succulent stems of candelabra tree, Euphorbia ingens, dark green but devoid of any real foliage, are striking in the right situation. These stems resemble those of unrelated cactus, with longitudinal ridges topped with spines. Although botanically interesting, the minute greenish yellow flowers that bloom in autumn and winter on the ridges of the upper portions of the upper segments are not much to look at. Deep red seed capsules that turn purple as they ripen sometimes develop in milder climates after the flowers are gone, but are almost never seen locally.
Good exposure is preferred. Candelabra tree are better structured and more prominent standing alone away from other larger trees and shrubs. Cool winters and occasional frosts limit their height to not much more than fifteen feet; and unusually cold frost can actually kill big specimens back severely. However, in sheltered areas and milder climates, candelabra tree can get twice as tall. Soil should drain very well and get dry between watering. Regular watering can cause rot, particularly in dense or rich soil.
The main problem with candelabra tree is the remarkably caustic latex sap, which can be dangerous to children, chewing dogs or even those who need to prune the stems. Fortunately, candelabra tree needs very little attention, and only needs to be pruned where the stems get in the way or start to lean against fences or roofs. The caustic sap prevents insect problems.

Freeman Maple

Red maple combines with silver maple.

It combines the autumn foliar color of red maple with the lacier foliar form of silver maple. Freeman maple, Acer X freemanii, is a hybrid of the two. It occurs naturally where ranges of its parents overlap. However, most modern garden cultivars are products of intentional hybridization. Like silver maple, it does not need much chill to exhibit autumn foliar color.

Freeman maple inherits other attributes from both its parents. It combines rapid growth of silver maple with structural integrity of red maple. Although it gets bigger than red maple, it is not as imposing as silver maple. It develops high branches like silver maple, but also is symmetrical like red maple. Big roots are about as complaisant as those of red maple.

Mature Freeman maple trees can grow about forty feet tall and broad. Autumn foliar color is vivid orange and red, and lasts longer than that of red maple. Since Freeman maple is a hybrid, it is mostly sterile. It can not generate an annoying abundance of seed. Nor can it naturalize in favorable climates. It is an exemplary maple for mild climates such as this.

Eastern Red Cedar

Eastern red cedar is actually a juniper.

One of the less common and certainly least familiar of junipers happens to be the most culturally and environmental significant juniper in North America, even though it is not even known as a juniper. Juniperus virginiana is instead known as the Eastern red cedar. It has a vast range, including every state east of Colorado, as well as Quebec, Ontario and even Oregon to the west. In some areas within and near the natural range, fire suppression has allowed Eastern red cedar to become invasive.

Mature trees are mostly less than fifty feet tall, but are the biggest evergreen trees in Kansas nonetheless. The largest Eastern red cedars can get almost ninety feet tall. Most are well branched from top to bottom unless pruned for clearance. The fibrous bark is ruddy brown, but not often seed from the outside.

Foliage and fruit are rather variable. The prickly juvenile leaves of young plants and interior stems of mature plants can be rather annoying. The scale-like adult leaves are more typical of junipers. Male trees produce pollen that can be a significant allergen. Female trees produce sporadic, small berries in blue or purplish black, that are quite popular with certain birds through winter.

Prior to the discovery of the incense cedar in the west, Eastern red cedar was the common aromatic cedar that was used to make pencils and to laminate cedar chests and closets to protect woolens and natural fibers from moths. Since it is so repellent to insects and decay, it is commonly used as fence posts. Native American Indians also used posts of Eastern red cedar, painted red with blood of the animals they hunted, to mark the boundaries of their hunting ranges. The name of Baton Rouge, which means ‘red stick’, was actually derived from such marking posts.

During the Dust Bowl drought of the 1930s, and before becoming known as a potentially invasive species, Eastern red cedar was promoted by the Prairie States Forest Project as a resilient wind break. They tolerate drought, harsh exposure and inferior soil. They can be planted close together to fill out and gain height more efficiently. More information about Eastern red cedar can be found where I got much of this information, at the Great Plains Nature Center.

Norway Maple

Norway maple looks like a sycamore.

It is rare now, but Norway maple, Acer platanoides, was once common as a street tree. A few are prominent within neighborhoods that were developed in the 1950s and 1960s. It resembles the common London plane. In fact, its botanical name translates to ‘maple like a plane tree’. Unfortunately though, the roots are perhaps too aggressive with pavement.

Norway maple defoliates somewhat more efficiently than London plane tree. However, in spring, it refoliates significantly later. Otherwise, it is a splendid shade tree. A few modern cultivars exhibit bronzed foliage that yellows for autumn. One exhibits variegated foliage. Another has chartreuse foliage. ‘Schwedleri’ was once the most common bronze cultivar.

Very few Norway maples are taller than forty feet within the mild climates here. They can grow significantly larger in cooler climates, such as the Pacific Northwest. Their palmate leaves are about five to nine inches wide. New trees are rarely available from nurseries, so require special ordering. Norway maple is not overly discriminating in regard to soils. It prefers regular irrigation through summer warmth.

Queen Anne’s Lace

Queen Anne’s lace is pretty but toxic.

There are actually a few different flowers known as Queen Anne’s lace. The most common species, Daucus carota, that has naturalized and even become somewhat of a weed in some areas, has two and a half inch broad, flat-topped trusses of delicately minute but abundant flowers, with a single red flower at the center of each truss. Apparently, Queen Anne pricked a finger with a needle while making the lace, leaving a drop of blood. Modern varieties have broader and fluffier trusses, often lacking central red flowers. They are a popular ingredient or fill for mixed bouquets with more colorful flowers.

The biennial foliage of Queen Anne’s lace grows to about three feet tall in the first year, with weedy but intricately lacy leaves. It blooms in summer of the second year. It is very similar to poison hemlock, which is poisonous enough to kill Nero, so should not be allowed to grow in vegetable gardens or where toxicity might be a problem; just in case.

Valley Oak

Valley oak is a stately tree.

Native trees are not necessarily the best options for home gardens. Valley oak, Quercus lobata, for example, grows much too large. Old trees can grow more than a hundred feet tall. Although unpopular for new plantings, it sometimes self sows. Also, new landscapes sometimes develop around old trees. Formerly rural trees therefore become urban trees.

Old trees are unfortunately very sensitive to disruption of their surroundings. Grading can severely damage their shallow feeder roots. Irrigation to sustain new landscapes is likely to promote rot of older and larger roots. Trees that should live for centuries can succumb to such damage within decades. Younger trees are fortunately adaptable to landscapes.

Nonetheless, young valley oaks are trees for future generations. Also, they require plenty of space. Although it may take a few centuries, trunks can eventually grow ten feet wide. As they mature, such big trees can make a big mess. The deciduous foliage can shed for weeks instead of days. The pale yellowish brown autumn foliar color is rather mundane. Without excessive irrigation, roots are remarkably complaisant.

Blood Red Trumpet Vine

Blood red trumpet vine can get aggressive.

Abundant lush foliage is actually the main asset of blood-red trumpet vine, Distictis buccinatoria, with the sporadic clusters of three inch long tubular flowers blooming as an added benefit during warm weather. Bloom can certainly be impressive when least expected though; and has a sneaky way of getting a late blast of color out during Indian summer weather patterns, when the weather gets warm after a cool phase in autumn. Contrary to the name, the flowers are more ruddy orange with yellow throats than blood red. The rich green leaves are compound, with a pair of three inch long leaflets and a three fingered tendril reaching out from between.

The vines are somewhat aggressive and can climb more than twenty feet, so need adequate support. They should not be allowed to overwhelm smaller or slower plants, or escape out of reach into adjacent trees. The tendrils can grab onto and damage shingles and light fences, but are an advantage for covering chain link fences. Given the opportunity, blood-red trumpet vine can even climb rough cinder block or stucco walls.

Chinese Pistache

Chinese pistache develops fiery foliar color.

Chinese pistache, Pistacia chinensis, does not need too much chill to begin to turn color. In some climates, it is already yellowing. With cooler weather, it will develop fiery orange and red foliar color. Not only does it color reliably with mild weather, but it actually retains its color better. It could defoliate more efficiently within frostier, windier or rainier weather.

Chinese pistache grows about thirty feet tall and broad. Old trees can eventually grow to about forty feet tall. Some old trees are female, so can produce annoyingly abundant red berries. Modern trees should be fruitless male cultivars. Pinnately compound leaves are about nine inches long, with a dozen or so leaflets. Leaflets are two or three inches long.

Because of its resiliency, Chinese pistache is among the more popular shade trees here. Established trees do not need much irrigation and can likely survive with none. Frequent irrigation can promote shallow root dispersion, which can damage pavement. Otherwise, Chinese pistache is a good street tree. It merely needs pruning for clearance over roads, sidewalks and driveways.

Sticks on Fire

Sticks on fire is a more colorful and more compact version of pencil tree.

The old fashioned pencil tree, with leafless, succulent stems is a strikingly strange plant already. In mild climates of coastal Southern California, it can get quite large, nearly ten feet broad and twice as high. Sticks on Fire, Euphorbia tirucalli ‘Sticks on Fire’, stays less than half as large, but is even weirder because the stems are so oddly colored.

The inconspicuous leaves drop almost as soon as they develop, leaving distended fleshy stems that are either reddish or yellowish orange. Stems fade to softer yellow through summer, and then turn red in winter. Size and growth rate are limited by a lack of chlorophyll. Although related to poinsettia, the flowers of sticks on fire are not significant.

Sticks on fire prefers full sun exposure and warmth, but unfortunately needs protection from frost during winter. It can be happy under an eave on a south or west facing wall, or in a large tub that can be moved to shelter during winter. Plants in tubs are a bit more sensitive to rot if watered too frequently. The sap of sticks on fire is very caustic to skin and can be dangerous if it gets in the eyes.
