Pink Iceplant

Pink bloom is merely a bonus.

Lavender pink bloom in spring or early summer can be profuse in sunny situations. Individual flowers are like small daisies with yellow centers. They stay closed through most of the morning, then open by about noon. If the weather is conducive, they can be slightly fragrant. However, the evergreen foliage of pink iceplant, Oscularia deltoides, might be even more appealing than the bloom.

The plumply succulent leaves are a delightfully bluish hue of gray. With two sides and a flat upper surface, these leaves are triangular in cross section. Blunt foliar teeth provide a distinctive texture. Foliage is so dense that the relatively thin stems within are barely visible. Stems can blush with pink or purple. Bloom is better, and foliage is denser, with good exposure and occasional watering.

Mature growth gets at least half a foot deep, and can eventually get a foot deep. It slowly spreads about two or three feet wide. With age, outer stems develop roots where they lay on the soil, and spread even farther. New plants grow very easily from cutting. Pink iceplant cascades nicely from pots or over stone. It contrasts handsomely with richer or darker colors of other foliage or bloom.

Burro’s Tail

My pictures are missing, so I found this one online without copyright protection. It demonstrates the cascading habit of burro’s tail.

Back when big spider plants or Boston ferns suspended in fancy beaded macrame were all the rage through the 1970’s, burrow’s tail, Sedum morganianum, was an unusual but also trendy succulent perennial for sunny spots in the home or sheltered and slightly shaded spots in the garden. The refined foliar texture and light bluish green color contrasted nicely with the big and deep green leaves of comparably trendy philodendrons. The thin stems are too limber to stand up, but cascade excellently. Plants in the garden that get pruned back while dormant in winter can easily get two feet long through summer. Without pruning, big plants can get longer than six feet. Pruning scraps and even the small but plump leaves can be rooted and grown into new plants. It is impossible to prune or even move burro’s tail without dislodging some of the leaves anyway. Watering should be regular but not excessive, but then minimal for plants in the garden through winter.

Arizona Cypress

Arizona cypress can be strikingly blue.

If Hetz blue juniper grew as a tree, it might look something like Arizona cypress, Cupressus arizonica. The evergreen foliage of modern cultivars is almost as blue as blue spruce. Older trees that grew from seed (not cloned) can exhibit significant genetic variability, and are more grayish green than blue. Some are stout and shrubby. Taller specimens might exhibit sculpturally irregular form.

In the wild, Arizona cypress is even more variable, with as many as five distinct varieties. Some varieties are sometimes classified as separate species. Shorter types may get no taller than a two story house. Taller types get twice as tall, and as wide as thirty feet. Trunks can get two feet wide. Smooth Arizona cypress has patches of distinctively flaking bark over shiny chestnut brown bark.

Arizona cypress are best where they can develop their natural form. They prefer no more than minor pruning of awkward stems. Although, none seem to mind grooming to eliminate dead or aging stems. Modern cultivars are more conducive to minor pruning than older trees. Some cultivars supposedly make nicely dense shorn hedges. Furthermore, shearing enhances the blue foliar color.

Curve Leaf Yucca

Curve leaf yucca can be variegated.

Some perennials are too easy to grow. Curve leaf yucca, Yucca recurvifolia (or Yucca gloriosa ‘Tristis’), is remarkably resilient. It migrates slowly but surely. If it becomes obtrusive, it is difficult to contain and remove. Removal of foliar rosettes above does nothing to slow the roots below. The roots merely produce new foliage. Of course that can be a distinct advantage for harsh conditions.

The striking foliar form resembles that of other species of Yucca, except that it reliably arches softly downward. Foliage is not as soft as it seems though. Each leaf terminates with a sharp spine. Sharp edges can cause wicked paper cuts. Foliar color is bluish gray. Although, variegated cultivars are increasingly popular. Old plants can develop trunks that slowly grow more than six feet tall.

Tall and elegant spikes of relatively small creamy white flowers stand grandly above the evergreen foliage in late spring or summer. Bloom is best with warm and sunny exposure, and lasts a long time. Viable seed is rare. Propagation by division of some of the many pups is simple though. Popular variegated cultivars exhibit more docile growth with fewer pups, but bloom less abundantly.

Statice

Statice is so popular as a cut flower that it should be more popular than it is in home gardens.

The papery flowers of annual statice, Limonium sinuatum, are so popular as seemingly synthetic dried flowers that many garden enthusiasts are surprised to find that they are happy to bloom naturally in home gardens. The clear shades of blue, purple, pink, orange, yellow and white seem to be dyed. The one or two foot tall flower stems are outfitted with odd papery ‘wings’ that make the stems seem wider than they actually are. Deeply lobed basal foliage forms shallow rosettes. Mature plants are about one or two feet tall, and a foot or so wide. Bloom begins late in summer, and continues into autumn. Good sun exposure and good drainage are preferred. Seed can be sown directly, or young plants can be added to the garden early in spring.

Freeman Maple

Freeman maple colors with minimal chill.

It is a hybrid. It is naturally occurring. Yet, most cultivars (garden varieties) resulted from intentional hybridization and selection. It is not as strange as it seems. Freeman maple, Acer X freemanii, is a naturally occurring hybrid of silver maple and red maple. It grows wild where the natural ranges of the parents overlap. From their example, breeders learned to selectively breed the cultivars.

These cultivars combine the fast growth rate of silver maple with the structural integrity of red maple. None get to be as imposing as the silver maple. Some get to be about forty feet tall and wide, which is a bit bigger than red maple gets in local climates. Foliage is lacy like that of silver maple, but more substantial, like that of red maple. It develops brilliant orange and red color for autumn.

Freeman maple, although locally uncommon, is one of the more practical maples here. Like silver maple, it does not require much chill in winter. Like red maple, it develops a symmetrical canopy with reasonably high branches. Roots should be complaisant with concrete. Because it is a hybrid, it is mostly sterile. It does not produce enough seed to be invasive in more conducive climates.

Coral Bells

Coral bells can bloom again in autumn. (This is not my picture.)

From Santa Barbara to Vancouver, and also in central Idaho, the humble native coral bells, Heuchera micrantha, is not much to look at, with compact rosettes of relatively small and bronzy rounded leaves with weird tomentum (hairs). In spring and early summer, and sometimes again in autumn, sparse trusses of minute brick red flowers hover about a foot above on wiry and slightly fuzzy stems. Old plants that get bare in the middle can be divided into several small plants in spring or autumn.

Modern cultivars are considerably more interesting, with more substantial foliage in various shades of green, gold, tan, brown, bronze and purplish bronze. The larger and variably lobed leaves can be two inches wide or slightly wider. The flowers stand as much as two feet high, but lack color. Most are pale greenish white. ‘Palace Purple’ has deep bronze or almost purplish foliage. ‘Ruffles’ has deeply lobed and ruffled green leaves. Unlike undemanding wild plants that can grow in cracks in exposed stone, modern cultivars like rich soil. Harsh exposure can scorch foliage, so a bit of partial shade is preferred.

Most coral bells are grown more for their colorful and low foliage than for their bloom. (Both pictures here were obtained online. I can not find my pictures.)

Incense Cedar

Incense cedar produces delightfully aromatic wood.

Nowadays, the delightfully aromatic foliage is familiar primarily in garlands at Christmas time. Most of the foliage of old trees is too high up for direct contact. Young trees with low foliage are rare. Incense cedar, Calocedrus decurrens, is unfortunately not as popular as it was a century ago. At that time, it was as utilitarian as it was appealing for spacious but minimally irrigated landscapes.

Incense cedar wood made good shingles and laminate for closets and cedar chests. The wood is aromatic enough to repel moths from woolens and furs, which were still popular then. It was less expensive to import than Eastern red cedar. It grows wild relatively nearby, in the Sierra Nevada and Cascade Mountains. Incense cedar fence posts might resist decay as well as redwood posts.

If the wild, where they compete with other trees for sunlight, old trees can get almost two hundred feet tall. However, well exposed old trees in Victorian gardens are less than half as tall after more than a century. Their canopies are generally conical. Large limbs can curve upward like extra trunks. Flat foliar sprays resemble those of arborvitae. The deeply furrowed bark is cinnamon brown.

Valley Oak

Valley oak is also known as ‘roble’.

From the north end of the Sacramento Valley to the San Fernando Valley, the valley oak, Quercus lobata, is among the most familiar and distinctive of native oaks. It is the largest oak of North America, reaching more than a hundred feet tall with trunks as wide as ten feet, which is why it is rare in urban gardens. The hundred fifty foot tall ‘Henley Oak’ of Covelo is the tallest hardwood tree in North America. The oldest trees are about six centuries old.

The two or three inch long leaves have deep and round lobes. The foliage turns only dingy yellow and then brown in autumn, and can be messy as it continues to fall through early winter, particularly since the trees have such big canopies. The gnarly limbs are strikingly sculptural while bare through the rest of winter. The gray bark is evenly furrowed.

Incidentally, Oakland, Thousand Oaks, Paso Robles and various other communities within their range are named for valley oaks. (‘Roble’ is the Spanish name.)

Chrysanthemum

Chrysanthemums are just right for autumn.

Mild autumns and arid summers keep chrysanthemums on a different schedule here than in most other regions. They can get planted in spring to grow through summer and bloom through autumn; but because they can take a bit of work, they are more often planted while blooming in autumn. Although commonly grown as autumn annuals, they are perennials that can regenerate next spring, grow through summer, and bloom even better the following autumn.

Centuries of development in Japan have produced more varieties of chrysanthemums than can be documented. There are really some weird types grown for cut flowers or by hobbyists. Garden varieties are mostly limited to simpler flowers that do not need much thinning or staking. Color ranges through all sorts of hues and shades of yellow, orange, red, pink and bronze, as well as a few purplish colors, cream and white. Many have yellow centers. The aromatic foliage is alluring to some, but objectionable to others.
