Star Magnolia

70315Before its new lime green foliage emerges, the otherwise modest star magnolia, Magnolia stellata, dazzles with a surprising profusion of crisp white, blushed or pale pink bloom. The three inch wide flowers have between a dozen and two dozen floppy petals (which are actually tepals). If the weather is right, the flowers might be slightly fragrant. If only bloom could last longer than it does!

Star magnolia is too small to be much of a tree, but too open and sculptural to be shrubbery. It grows slowly and might never reach downstairs eaves. Only the biggest trees might reach the lower sills of upstairs windows. However, the angular low branches, usually on multiple trunks, are ideal for displaying the distinctive bloom. The light gray bark resembles that of fig trees. Leaves are about four inches long, and an inch and a half wide. Foliage turns soft yellow before falling in autumn.

Candytuft

80321It looks like sweet alyssum, but is not even close. The tiny white flowers and finely textured foliage work almost as well for similar uses in the landscape. In fact, the plants are most often grown as short term warm season annuals. However, candytuft, Iberis sempervirens, is really a perennial that can be cut back in autumn, regenerate through winter, and bloom for spring and early summer.

One must really examine candytuft closely to see that it is related to cole crop vegetables like broccoli, cauliflower, cabbage and Brussels sprouts. That is why is has an odd aroma when cut back. Mature plants have the potential to get nearly a foot deep, but typically stay lower. They can spread a bit wider than a foot. Candytuft can tolerate a slight bit of shade, but prefers sunny exposure.

If planted closely together, candytuft can form a nice small scale ground cover. It mixes nicely with stones, and cascades slightly over the edges of low stone retaining walls. It is more substantial than sweet alyssum, and works better for permanent planting in borders and along walkways. The barely perceptible floral fragrance of individual plants can be quite appealing in larger volumes.

Look What The River Washed In!

P80224KWhat is it?!?

Is it alive?

Was it alive?

Is it moving?

Should we roll it back into the river?

Can we eat it? Someone actually asked that.

It really is as big and ugly as it looks. That is a size 11 boot next to it to demonstrate how big it is. We can not eat it. There is no need to put it back into the river. It is not moving. It was alive, and still is. It is the distended tuberous root of a wild cucumber, of the genus Marah, which is also known as ‘manroot’ because of how big it can get. That stub protruding from the top (toward the top of the picture) is the remnant of a stem. A few thin roots protrude from the lower half, with thicker root stubs at the bottom.

This picture was taken last winter after the San Lorenzo River flooded and then receded. There has not been enough rain this year to wash more than leaves and a few pinecones downriver.

If this tuberous root had not been unearthed and scoured clean by floodwater, it would have been actively growing through winter. The surprisingly thin and wiry vines appear in autumn and climb with tendrils over shrubbery and small trees. The palmately lobed leaves are rather fragile, and tear easily. Loose clusters of small pale white flowers are followed by weirdly spiny round fruit that ripens from light green to greenish yellow. Each fruit is about the size of a golf ball, and contains a few big seeds. As the weather gets warm in summer, the vines die completely to the ground, leaving the drying fruit dangling from whatever the vines grew onto earlier.

Why can’t the river bring us something useful?

Cineraria

80314This is an extreme bloomer! Cineraria, Pericallis X hybrida, blooms with composite flowers, which means that each small daisy flower is really a whole bunch of minute flowers clustered together to look like a single flower. As if this were not impressive enough, a whole bunch of these composite flowers are clustered together on top of each big wide floral truss. They are not easy to ignore.

Blue, red, purple or pink bloom can be so profuse that the rich green basal foliage is only visible around the edges and below the domed trusses. Individual flowers usually (but not always) have white halos around dark centers. The soft leaves below are somewhat wide and rounded, with variably toothed margins. Big plants can get as high and wide as a foot. Some are more compact.

Cinerarias are most often obtained while blooming, enjoyed as potted plants, and then discarded after bloom, although with a bit of effort and shelter from frost and heat, they can be sustained as potted perennials to bloom again. They can be grown as short term bedding plants after frost in spring, but they require a slight bit of partial shade, regular watering and richly organic medium.

Almond

70301It is known more as a small to mid-sized shade tree that produces edible nuts, but almond, Prunus dulcis, also blooms magnificently as soon as the weather allows. Actually, it often blooms a bit earlier than it should. Nut production can be ruined if rain dislodges blossoms or developing nuts. The profuse white flowers are small but slightly larger than those of other related stone fruit trees.

Yes, almond is the same genus as apricot, cherry, plum, peach and the other stone fruits. The fruit is actually very similar, but instead of developing into sweet flesh, it merely forms a hull that dries and separates from the nut within. The nuts are the large seeds or stones, like peach pits that can be eaten. Hulled but unshelled almond nuts are about one or two inches long. Because the nuts get shaken from trees instead of picked, trees can be allowed to get about two stories tall.

Transvaal Daisy

80307There is some controversy about the identity of the flowers that Micky Mouse picks at the porch to present to Minnie Mouse when she answers the door. Some insist that they are Transvaal daisy, Gerbera hybrida. When they are not in black and white, the substantial daisy flowers are cartoon hues of yellow, orange, red, pink and white, sometimes with chocolatey brown or black centers.

Transvaal daisies are always available as cut flowers, but bloom best in cool spring and autumn weather in home gardens. Most garden varieties have single flowers on bare stems. Most cut flowers are semi-double. Double flowers that resemble zinnias, and spider flowers that resemble spider mums, are rare. Coarse basal foliage gets almost a foot high and a foot and a half wide.

Because the foliage is so vulnerable to snails, Transvaal daisy is usually grown in pots rather than in the ground or immobile planters. Besides, potted plants can be brought into the home or put in prominent spots while blooming, and then put out of sight between bloom. Transvaal daisy wants partial shade, regular watering and occasional feeding. It can take full sun exposure if not too hot.

Rocky Mountain Juniper

70222It is no coincidence that many plants with gray foliage are from mountains or deserts. Gray foliage is ‘glaucous’, which, like glaucoma, diffuses light. This helps to protect it from desiccation and scald when sunny weather is also hot, windy or arid. The glaucous foliage of Rocky Mountain juniper, Juniperus scopulorum, is what distinguishes it most from related North American junipers.

Garden varieties of Rocky Mountain juniper are even grayer than wild plants. Some are even silvery. Also, they tend to maintain a somewhat symmetrical form. Most are compact, with dense evergreen foliage. Some loosen up with age. All want full sun, and seem to enjoy warmth. They lean away from shade. Color seems to be better if plants get watered occasionally through summer.

‘Skyrocket’ is very narrow while young, like a small silvery Italian cypress that gets only about fifteen feet tall. ‘Blue Arrow’ is similar, and becoming more popular because it is more resistant to disease. ‘Medora’ and ‘Cologreen’ are more bluish green. All get plump with age. ‘Wichita Blue’ and ‘Moonglow’ are more conical. ‘Wichita Blue’ is more bluish. ‘Moonglow’ is more silvery gray.

Oregon Grape

80228Oregon has good taste. Douglas fir, one of the most useful of timber trees in America, was selected as the state tree. Oregon grape, Mahonia aquifolium, was designated as the state flower. Although the tight clusters of tiny bright yellow flowers that bloom about now may not be as flashy as other state flowers, they contrast handsomely against the glossy and deep dark green foliage.

The pinnately compound evergreen leaves are larger than they seem to be. The smaller individual leaflets that resemble holly get noticed first. They are are not quite as wavy, spiny or thick as leaves of English holly are, so can work well where spiny foliage would be objectionable. Dark grayish blue berries are not abundant, but happen to make good jelly for those who hunt for them.

Mature plants get about five feet tall and broad, and can spread wider like Heavenly bamboo does. Foliage might be a richer shade of deep green, with a slightly more relaxed texture, in partial shade. A few garden varieties are available, including some that are more compact, and some with more rounded leaflets. Old canes should be pruned out as they get replaced by newer canes.

Daphne

70215When the weather warms up a bit between frosty weather and winter storms, the rich fragrance of winter blooming daphne, Daphne odora, is at its best. The domed trusses of tiny pale pink flowers are not much wider than a quarter, so are easy to overlook while investigating the source of the fragrance. ‘Aureomarginata’, the standard cultivar, has glossy evergreen leaves with narrow pale yellow margins. Mature plants are only one or two feet high. All parts of the plant are incidentally toxic.

It is no mystery why daphne is rare. It can be rather finicky, and unpredictably so. It purportedly wants rich and slightly acidic soil, in a warm but partially shaded spot; but can be difficult to grow even in ideal conditions. Yet, it is sometimes seen doing well in full sun or in dense soil of questionable quality. To make matters worse, even the healthiest plants live only about five to eight years.

Snowdrops

80221Where winters are more wintry, garden enthusiasts get to brag about their snowdrops as they emerge and bloom through melting snow. Diminutive white flowers against a backdrop of white snow may not look like much to us. We have more colorful flowers through winter, without the snow. Their kind of snowdrops, Galanthus specie, need more winter chill than they would get here anyway.

We have our own kind of snowdrops though. Leucojum aestivum does so well without significant winter chill that it can naturalize, and sometimes shows up in well watered gardens and riparian areas without being planted intentionally. Leucojum vernum is similar, but blooms with only single or paired flowers, rather than three or more small and pendulous flowers on each arching stem.

The rubbery leaves are about half an inch wide and a foot tall. They stand rather vertically, and can get nearly twice as tall if they need to grow through groundcover. The flower stalks are about the same height, and with the weight of the drooping flowers, might lean a bit outward from the foliage. Each flower has six white tepals with a yellowy green spot near the tip. All plant parts are toxic.
