‘Shrubbery’ sounds so unflattering for a pine; but mugo pine, Pinus mugo, is not really much of a tree. The tallest trees do not reach eaves. Most old trees are only a few feet tall and about twice as broad, with strictly rounded form, and dense forest green foliage. The stout paired needles are only about one or two inches long. The plump cones, which are rarely seen, are not much longer.
Although very rare in other types of landscapes, and originally from the Austrian and Italian Alps, mugo pine is one of the most popular and traditional features in Japanese gardens. Even though it grows very slowly, it should have enough room to do so without competing with other more aggressive plants that might overwhelm it. It should neither be shorn nor pruned back too aggressively.
This is one of those perennials that has mixed reviews. Although relatively tough once established, holly fern, Cyrtomium falcatum, is susceptible to rot and fungal leaf-spot. It likes to be watered somewhat regularly, but rots if the soil is constantly saturated. Leaf-spot is not as dangerous as it looks, but can be unsightly. Too much fertilizer (to correct the damage) can burn the foliage too.
This ain’t no ordinary maple. Although there are other maples with trifoliate leaves (divided into three distinct palmately arranged leaflets), box elder, Acer negundo, is the only maple with pinnately compound leaves (divided into three or more distinct leaflets that are arranged pinnately on a central rachis). Leaflets might be solitary too. Almost all other maples have palmately lobed leaves.
New and improved is not always better. Modern garden varieties of zonal geranium, Pelargonium X hortorum, with bigger, fuller and more profuse blooms, are more colorful than the relatively weedy classic varieties, but they are considerably more demanding. In fact, because they are so unhappy through winter, they are often grown as warm season annuals instead of as perennials.
Colorado is another state that was able to designate one of the most excellent wildflowers of North America as the Official State Flower because it happens to be native there. Rocky Mountain columbine, Aquilegia caerulea, however, did not contribute as much to the breeding of the many modern hybrid varieties of columbine as did common European columbine, Aquilegia vulgaris.
Compared to extensively bred garden varieties, wild roses are not much to look at. Their tiny flowers do not get much wider than two inches, and may not get much wider than those of blackberry, with only about five petals. Flower color ranges only between pale luminescent white and pale pink. Bloom is typically rather brief in mid spring. Only a few healthy specimens bloom again later.
The valley oak of the Sacramento Valley, San Joaquin Valley, and coastal valleys to the west, is the grandest oak of North America. Within the coastal half of that range, and extending down past San Diego, the coat live oak, Quercus agrifolia, is a nearly comparable second grandest. The biggest subjects may be as tall as seventy feet, and nearly as wide, with trunks wider than ten feet!
Window boxes were supposedly invented in Venice to contain aromatic plants that repelled mosquitoes (and probably because garden space was so minimal in Venice). Hanging plants like nasturtium and ivy geranium are traditional window box plants because they do not obscure scenery or sunlight. Scented geraniums are also popular because they are be so strongly aromatic.
Oh, how breeding complicates things. Many years ago, there were only six basic types of wax begonia, Begonia semperflorens-cultorum, with three choices for floral color, and two choices for foliar color. Bloom was white, pink or red. Foliage was either green or dark bronze. Although these choices have not changed, some modern hybrids are difficult to distinguish from other species.
A few years ago, it was known as Santa Catalina Island ironwood. However, the rare subspecies native to Santa Catalina Island lacks the distinctively angular foliar lobes of the Santa Cruz Island ironwood, Lyonothamnus floribundus ‘aspleniifolius’. The evergreen compound leaves are about five inches long and four inches wide with three or five narrow leaflets, and look like chicken feet.
