It may not bloom profusely, but cape honeysuckle, Tecoma capensis, blooms sporadically at random times throughout the year, and often while not much else is blooming. The bright reddish orange flowers contrast nicely against glossy evergreen foliage. Some blooms are slightly more reddish, while others are slightly more orangeish. A somewhat more compact cultivar blooms with light yellow flowers.
The long and limber stems of cape honeysuckle can not decide if they want to grow as vines or as shrubbery. They can be tied back and espaliered against a fence or trellis, or pruned and left to stand on their own. Large plants can get higher than the eaves. Overgrown thickets of stems can be cut down to the ground at the end of winter. They can regenerate and resume blooming before summer.
The narrow tubular flowers are about two inches long. They develop in terminal trusses, but only a few within a truss bloom at the same time. Shade inhibits bloom. Fertilizer seems to inhibit bloom by promoting vigorous vegetative growth. Fortunately, these vigorous shoots eventually bloom as vigorously as the grew. The four or five inch long leaves are pinnately compound, with five to seven small serrate leaflets.
The same cooling weather that is initiating fall color is what finishes the zinnias that bloomed so colorfully through summer. Like tomatoes, they can stay out in the garden until they succumb frost if they continue to perform, and if the space they occupy is not needed for something else. There should be no guilt with replacing them sooner. After all, they are technically warm season annuals.
Good old-fashioned Heavenly bamboo, Nandina domestica, which can almost reach the eaves, can be difficult to obtain nowadays. More compact modern cultivars do not get much more than six feet tall, and some stay less than three feet tall. Foliage is airier in partial shade, but more colorful where more exposed.
Just like African marigold that was featured earlier is actually Mexican, German primrose, Primula obconica, is actually Chinese. As odd as it is, the common name is an improvement from the former name of ‘poison primrose’, which was derived from the potentially irritating sap of the unimproved species before it was bred to be less toxic, as well as more colorful and prolific in bloom.
What an odd name. It sure sounds interesting, like some sort of exotic fruit tree. Alas; argyle apple is a eucalyptus; to be specific, Eucalyptus cinerea. Compared to most other eucalypti, it stays rather low. It barely gets as tall as a two story house, even if it gets broad enough to shade most of the backyard. The rusty brown bark becomes roughly furrowed. The irregular branch structure can be quite sculptural.
French Marigold might have been a more appropriate choice. It is the official flower of Dia de los Muertos on November 2. Some might say that the bigger and bolder African marigold, Tagetes erecta, is just as official. Both are Mexican, but as the names imply, most varieties of French marigold were developed in France, and most varieties of African marigold were developed in Africa.
They compare to more traditional roses like instant coffee compares to real coffee. They are too easy and cheesy. However, even instant coffee can be rather good as long it is not expected to taste like the real thing. Likewise, carpet roses do not produce big and fancy flowers on long stems for cutting, but they have other attributes that are advantageous in the landscape.
It is so tempting to dress up a densely conical dwarf Alberta spruce, Picea glauca ‘Conica’, as a garden gnome for Halloween. They are so symmetrical that they seem to have been shorn that way. They are too small to be classified as trees, but are not as shrubby as most shrubbery either. Their practicality is rather limited to formal situations where their strict symmetry is desirable.
