Iris fernaldii

Only four species of Iris are native here. The problem with identifying them is that three of them can be visually similar. Only Iris douglasiana is reliably and distinctively blue. Iris longipetala and Iris macrosiphon are generally pale blue, but can be as pale white with pale yellow veins as Iris fernaldii. Without keying it out, I can only guess that this particular iris is Iris fernaldii. The others seem to develop slightly larger and denser herds with slightly more upright foliage. Iris fernaldii develops relatively smaller herds and more relaxed foliage that does not stand as upright. Even what seems to be large herds are typically groups of smaller herds. Their flowers can lay almost on the ground. they shrivel too soon after cutting to work well as cut flowers. Nonetheless, they are a delightful native wildflower that is blooming as freely as it can where it grows wild. I really should relocate those that grow where they are not wanted, rather than discard them with other weeds. They might compete with weeds and other less visually appealing naturalized vegetation within areas that are not landscaped. Actually, they might be appropriate for a few areas that are casually landscaped.

Pacific Wax Myrtle

Pacific wax myrtle is the native version of bayberry.

From Washington to Southern California, the Pacific wax myrtle, Myrica californica, is native to coastal regions. It is the western counterpart to the bayberry, Myrica pen(n)sylvanica (or caroliniensis), of the East Coast. It makes a nice informal hedge with only occasional shearing, or an informal screen that only gets trimmed back when it gets too big. Mature plants can get nearly thirty feet tall in sheltered areas, but rarely get half as tall and wide, even if allowed to grow unimpeded. The glossy three inch long leaves are narrow with slightly undulate margins with small teeth.

Pacific wax myrtle functions something like glossy privet or some of the pittosporums that make good hedges, but is not so resilient to frequent shearing. Big stems that get cut back to not always produce new growth. The advantage of Pacific wax myrtle is that it is native, so does not want much water once established, so is happy in out of the way places that do not get watered or maintained. Like privets and pittosporums, Pacific wax myrtle can be pruned up as a small tree with multiple exposed trunks.

Californian Blue-Eyed Grass

Blue-eyed grass is not grass.

It is not a grass, and lacks eyes, but it is native to most of California and western Oregon. Blue-eyed grass, Sisyrinchium bellum, is related to iris, which actually sounds ocular. Its tiny flowers are typically rather purplish, but can be clear sky blue, or rarely white. Bloom continues through spring until summer dormancy. All foliage then dies back until autumn.

Blue-eyed grass develops small foliar tufts that expand quite slowly. It propagates easily from division of its thin rhizomes as it resumes growth in autumn. Plugging newly divided rhizomes adjacent to original foliar tufts accelerates expansion. Blue-eyed grass can self sow, but typically does so only sparsely. Its grassy foliage is typically less than a foot tall.

Although native and impressively resilient, blue-eyed grass appreciates a bit of moisture. However, it may never require irrigation, since it is dormant through the summer season. Irrigation might maintain foliage through much of summer, but if excessive, can cause rot. Blue-eyed grass prefers sunny and warm exposure, without contention from other plants.

Red Flowering Currant

Red flowering currant tolerates some shade.

Its natural range extends from coastal Santa Barbara County to central British Columbia. Yet, red flowering currant, Ribes sanguineum, is elusive in the wild. It is more commonly observable within relaxed landscapes of native species. Individual specimens might not perform for more than a decade but can disperse seed. It behaves as if it is growing wild.

Mature specimens of red flowering currant can grow ten feet high and half as wide. Most stay lower. It is an understory species, so it tolerates a bit of shade. It may prefer shade to warm exposures. Young specimens may be wobbly enough to justify temporary staking. Removal of deteriorating old stems promotes more vigorous growth on fresh new stems.

Pendulous conical trusses of small pink flowers bloom by late winter or very early spring. Before anyone notices, birds are likely to take the few small currants that might develop. Small palmate leaves resemble those of scented geranium, and are somewhat aromatic. They turn yellow as they shed for autumn. Red flowering currant has a foresty character. It suits casual landscapes which border or merge into undeveloped areas.

Wild Lilac

Some wild lilac can grow quite large, but lives only about thirty years.

There are many different forms of wild lilac, Ceanothus spp., ranging from low sprawling ground cover types that get only about two feet deep, to dense shrubs that get a few feet tall and broad, to relatively open and irregular shrubs that are a bit larger. The largest can become a small tree with multiple trunks as tall and broad as twelve feet. Wild lilac flowers can be any shade of blue ranging from deep dark blue to soft pale blue. Only a few have white or pinkish flowers. Some wild lilacs have leaves that are glossy and round like nickels. Others have small but thick and roughly textured leaves, like bacon bits.

However, almost all bloom in early spring, are evergreen, and want well drained soil. Only a few lose their leaves where winters are cold. Most prefer infrequent irrigation or none at all, although some of the ground cover types like to be watered occasionally through summer. Wild lilacs do not like to be pruned, and really do not want to be shorn, so should be planted where they have room to develop their natural forms. Sadly, wild lilacs are not permanent, and typically die within ten years or so.

Pacific Hound’s Tongue

Pacific hound’s tongue is reliably perennial.

Cat’s tongue might be a more fitting name. Pacific hound’s tongue, Cynoglossum grande or Adelinia grandis grows where it wants. It can grow from cracks in pavement, and then be difficult to remove. It grows easily through decomposed granite, gravel or wood chips. Yet, it is not readily available from nurseries, or as seed. It is sporadic in its native range.

Pacific hound’s tongue may be uncommon because it takes a few years to bloom well. It does not bloom for its first year from seed and then blooms thinly for its first few years. By its third year though, its resilient perennial taproot should be very established. Its foliage dies back soon after late winter bloom. It stays significantly longer with garden irrigation.

Bloom resembles that of forget-me-not, but relatively sparse and on vertical stems. Floral stems are about a foot tall, or can be two feet tall. They are more numerous in cultivation. The small blue flowers are less than half an inch wide. Foliage develops basal rosettes, which may prefer a bit of partial shade. The biggest leaves are less than six inches long, like a hound’s tongue.

California Bay

California bay is not culinary bay.

Grecian bay is, as its name suggests, endemic to Greece and the Mediterranean region. California bay, Umbellularia californica, is native to California and southwestern Oregon. The two are very different. Although California bay can be useful for culinary application, it is twice as pungent. For replacing Grecian bay in recipes, half as much should suffice.

California bay also grows much larger and more irregularly than Grecian bay. With good sun exposure, it grows more than forty feet tall. Where it competes for sunlight in forests, it can grow a hundred feet tall. Domestic trees typically develop on single vertical trunks. Wild trees might develop several leaning trunks. Foliar canopies are densely evergreen.

California bay is uncommon within urban home gardens because it is so big and messy. It is more likely to inhabit rural gardens either by self sowing or by being there first. Some old trees that grew from stumps of older trees can develop basal decay. Stumps might be difficult to kill. Foliar and floral detritus inhibits smaller vegetation and seed germination. Some abhor the foliar aroma.

Vaccinium

Vaccinium ovatum, California huckleberry

Cranberries have been elusive. I know of no one who grows them here. Furthermore, I am told that no one grows them here because they do not grow here. I am not convinced. They grow well in portions of western Oregon. Some of the riparian climates here are not too different from climates there. I am determined to try growing cranberries, even if I can grow only a few. Just this year, I procured seed that should vernalize through winter. If they grow, they will be comparable to those that grow wild within their native range, rather than a cultivar.

Blueberries were uncommon decades ago. I can remember, when I was a kid, being told that no one grows them here because they do not grow here, just like I am told in regard to cranberries. Well, nowadays, blueberries, although still uncommon, are not rare, and are actually somewhat popular among those who want to grow them. I grow a few only because I acquired them from a garden that they needed to be removed from. Otherwise, I would prefer to try cranberries. I can not complain about the blueberries, though. They are still here after a few years because they are reasonably productive.

Huckleberries, or at least one species of huckleberry, are native. Although quite rare within home gardens, and more typically grown as an alternative to boxwood rather than for berries, they can produce a few berries. They might be more productive if cultivated more for berry production than merely for aesthetic appeal. I have collected enough berries from wild colonies of huckleberry to make jelly, which is encouraging. It is also encouraging that the native huckleberry is Vaccinium ovatum, which is the same genus as both blueberry and cranberry. I wonder how different their cultural requirements are.

Elderberry

Blue elderberry is native here.

Although almost never planted intentionally, elderberries occasionally appear in strange places, wherever their seeds get dropped by the birds or rodents who eat their berries. The blue elderberry, Sambucus mexicana / caerulea, is native and most common between California, British Columbia and the Rockies. The American elderberry, Sambucus canadensis, is more common elsewhere, and also appears in the west where it had historically been imported for berry production. Some modern cultivars (cultivated varieties) with gold, bronze, or lacy foliage are actually related to European elderberries.

Except for compact cultivars, elderberries grow rampantly to about fifteen feet tall and wide. Aggressive pruning in winter keeps them looking fuller and more densely foliated. Overgrown plants can be rejuvenated by getting cut to the ground. The big leaves are divided into seven leaflets that are two to six inches long. Blue elderberry foliage is softly serrate and a bit more variable, with five to nine leaflets that may be as short as one inch.

Wide flat trusses of pale white flowers that bloom in late spring or early summer produce small but potentially abundant and richly flavored berries. Blue elderberries are dark blue dusted with white powder on trusses to about six inches wide. American elderberries are darker and more purplish on trusses that can be wider than eight inches. (Red elderberries are toxic!)
