Torch Lily In Fire Season

61214Okay, so this is not really the time of year that they should be blooming. Torch lily, Kniphofia uvaria, should bloom in the middle of summer. However, without watering, naturalized plants bloom when the weather prompts them to. Some wait out the warm and dry summer weather to bloom as soon as they get dampened by the first rains. Others bloom in spring, before things get too dry.

Flower stalks can get almost five feet tall, but are more typically about three feet tall. Small tubular flowers are arranged in dense conical trusses on top of these stalks. From the bottom to the top, red flower buds bloom orange, and then fade to yellow, and fold downward against the stalk. Different varieties bloom with more or less of these three colors, and at different times of the year.

The grassy foliage is not much to look at without bloom. By the end of winter, it can look rather grungy. It fluffs back nicely in spring, sort of like overgrown daylily foliage. Overgrown plants, or maybe just a few rhizomes, can be divided anytime. However, they should probably be divided just before the end of winter so that they can enjoy late rain, just before their spring growing season.

Dwarf Golden Arborvitae

71220These pale blue . . . whatever they are, were just too cool to pass up without a picture. Technically, they are the ‘cones’ of dwarf golden arborvitae, Platycladus orientalis (formerly Thuja orientalis) ‘Aurea Nana’. They do not look much like cones. They are only about three quarters of an inch long, and are rarely as profuse as they are here. They are less appealing as they dry and turn brown.

Dwarf golden arborvitae grows nicely while young, then slows significantly once it gets only a few feet high. Mature specimens may not get as tall as six feet, with nicely rounded form and cheery yellowish foliage. Other uncommon cultivars that are not dwarfed can eventually reach second story eaves, with greener foliage. Flat sprays of soft evergreen scale foliage is suspended vertically.

Foliage is brightest yellow when fresh and new in spring, and then fades somewhat through summer, so that it might be yellowish green by this time of year. In frostier climates, exposed tips can get bronzed through winter. Partial shade is not a problem, but subdues foliar color. Dwarf golden arborvitae, although quite resilient once established, prefers good soil and occasional watering.

Blue Princess and Blue Prince Holly

61207It is about time that someone reintroduced this technique! Blue Princess holly is now available together in the same pot as its male pollinator, Blue Prince holly (Ilex x meserveae ‘Blue Princess’ and ‘Blue Prince’). With careful pruning to prevent one from crowding out the other, both can coexist and provide profuse, bright red berries every winter, indefinitely. As the plants grow, their main trunks will eventually graft together.

Blue Princess holly is purported to be the shrubbier of the two. Blue Prince might be a bit more compact, and might grow a bit slower. Both eventually get about seven feet tall and nearly as broad, with remarkably glossy evergreen foliage. Their rather wavy leaves have sharply pointed teeth. Fortunately, their teeth are not quite as sharp as those of traditional English holly, which happens to be one of their mutual parents.

If possible, it might be helpful to identify the two cultivars of holly in a mixed planting, and label them so that neither one nor the other gets pruned out. Blue Prince will be the plant that produces no berries. Of course, with selective pruning ‘Blue Prince’ can be confined and subordinated to the showier ‘Blue Princess’. Individual ‘Blue Princess’ holly plants are better for hedges, with separate ‘Blue Prince’ plants nearby.

Parrot’s Beak

71213The Latin name is easy to confuse with the sacred flowers of an aquatic perennial from tropical regions of Asia, or a funny looking British sport coupe. Lotus berthelotii is a diminutive terrestrial perennial known as parrot’s beak. It gets only about a foot high, and spreads to only two or three feet wide. It cascades nicely from hanging pots, and is actually rarely planted out in the garden.

The bright reddish orange flowers bloom mostly in the warmth of spring and summer, but can bloom any time they are neither too hot nor too cool. They are about an inch long and ‘pea-shaped’, but they really look like parrot beaks. The finely textured gray foliage is comprised of small compound leaves that are divided into three or five very narrow leaflets that look like hemlock needles.

Parrot’s beak likes full sun and good drainage. It rots easily if soil is always damp. In hanging pots, it is usually sheltered from frost through winter, or can at least be moved to shelter prior to frost. Parrot’s beak can cascade nicely over the rims of urns of mixed perennials or annuals, but dies back through winter where such urns are too exposed. It is often grown as a warm season annual.

Goldenrod

61130Here on the West Coast of California, most of us know goldenrod only as a color of crayon. In most other parts of America though, it is a common wildflower that is colorful enough to be popular in home gardens. Yet, with more than a hundred specie, it is hard to say exactly which goldenrod, (Solidago spp.) the crayon color corresponds to. All are some shade of gold or yellow, but some are a bit more orange than others.

Most varieties of goldenrod that are available locally bloom in late summer or autumn. Some are still blooming prolifically now, on seemingly overloaded stems that stand taller than two feet. Shorter types that get only a few inches tall are probably unavailable. Perennial rhizomes spread slowly but surely, and can be divided to propagate new plants. Goldenrod needs full sun exposure, but not much water once established.

The blooms of goldenrod are just as interesting physiologically as they are colorful. The floral trusses of the most popular types are somewhat conical, but arching from their own weight. Each of these trusses supports a profusion of minute daisy-like flowers, which are actually composite flowers comprised of even smaller and more abundant florets! Bees and butterflies really seem to appreciate the floral redundancy!

Black-Eyed Susan

71206Is it coincidence that the Latin name of black-eyed Susan is Rudbeckia, or was Becky rude enough to give Susan her black eye? The dark center is something that all varieties have in common, and what distinguishes them from most of the related blanket flower varieties. The daisy flowers of black-eyed Susan are traditionally yellow. Modern varieties can be orange, reddish or bronzed.

Most Black-eyed Susan are perennials that bloom through summer and as late as the first cool weather of autumn. A few are annuals that bloom in their first year only through summer. They get about three feet tall, although some can get taller, and some stay quite compact. Flowers are about three inches wide. Some varieties have even larger flowers that fold backward like coneflower.

Black-eyed Susan appreciates an open and sunny spot with somewhat rich soil and occasional watering. Deadheading keeps them tidy, and for some varieties, promotes subsequent bloom. It also inhibits self sowing where that might be a problem. Modern varieties should not become invasive even if allowed to self sow. Mature colonies can be divided for propagation every few years.

Red Flowering Gum

61123We all know about the bad reputation of eucalypti, especially the notorious blue gum. They are too big, too aggressive, too messy, too structurally deficient, and in groups, they are too combustible. However, there are several eucalypti that are not only appropriate for local home gardens, but because of their resiliency, drought tolerance and adaptability to the local environment, should be more popular than they are.

Red flowering gum, Eucalyptus ficifolia (which is now known as Corymbia ficifolia), rarely gets more than thirty feet tall and broad, with a stout branch structure. It is a good street tree because the roots are usually deep and complaisant. Constantly falling leaves and seed capsules are somewhat messy, but the mess is proportionate to the compact canopy, and is probably worth the spectacular summer and autumn bloom.

Fuzzy trusses of staminate flowers are usually some shade of red, but might be pink, salmon, reddish orange or pale white. Trees must be a few years old to bloom, so color might be a surprise when young trees bloom for the first time. Profusion of bloom can be variable from year to year, or from one portion of the canopy to another. Tree size and form are also variable. Some are vigorous while others are more compact.

Coneflower

71129Known more as a medicinal herb, and by its Latin name, coneflower or Echinacea, is a delightful prairie wildflower that works just as well in refined home gardens. It blooms in summer and again in autumn, although autumn bloom can be inhibited if plants are not groomed of deteriorating stems from the previous bloom. Like related gaillardia and rudbeckia, coneflower is a nice cut flower.

Flowers start out like any other daisy flower, but then fold back with the long ray florets hanging downward around the more rigid centers of darkly colored disc florets, forming cones. Flowers can stand almost three feet high, mostly on unbranched stems. Many popular varieties stay lower. Leaves and stems are somewhat hairy or raspy. Old varieties were mostly purple or lavender. Newer varieties can be orange, yellow, red, pink, white or green. Big plants can be divided after autumn bloom, or in spring.

Mother In Law Tongue

61116What an unflattering name for such striking tropical foliage! The pointed and strap-shaped evergreen leaves of mother-in-law’s tongue, Sansevieria trifasciata, stand vertically, about two or three feet tall. They are rather rigid, and seem to be plastic with a glossy finish. Almost all modern varieties are variegated with silvery gray, white, cream or yellow stripes or banding. Dwarf varieties stay shorter, with flared foliage.

Because it tolerates shade and neglect so well, mother-in-law’s tongue has always been a popular houseplant. It is sometimes grown in pots outside where it can be sheltered from frost or direct sunlight that might roast the foliage. Pups can be divided from overgrown old plants, but will develop shorter leaves until they recover from separation. Crowded plants might get green sports (unvariegated mutant shoots).

Sweetgum

71122One of the big four for mild climates, sweetgum, Liquidambar styraciflua, develops an excellent display of mixed yellow, orange and red, regardless of how quietly autumn tries to sneak in. Of the other three, Chinese pistache is more orange with less yellow, flowering pear is more ruddy, and gingko is only bright yellow. They all get very flashy color, but sweetgum just might be the flashiest.

Some trees can favor one color or another. Distressed trees tend to be more pinkish red. Vigorous trees might have more yellow. Garden varieties were selected for reliable variability; although ‘burgundy’ has more dark red. Only trees that are too sheltered, too vigorous or pruned too aggressively will lack color. Urban trees can get fifty feet tall, but do not get very broad. Structural deficiency, aggressive roots and spiky seed capsules the size of ping pong balls can be problematic.
