There are those of us who can grow cabbage well, and there are the majority of us who wish we could. Mild winters allow cabbage to be grown in autumn as well as in spring; but warm weather can also compromise flavor and promote premature bolting (blooming), which ruins the heads. Cabbage demands rich soil and regular watering. If the weather is evenly mild, they dig that too.
Spring grown cabbage was planted last winter, about a month prior to the last frost. Now it is time for autumn cabbage, about a month or two before frost. New plants can be planted a bit deeper than they were originally grown, so that the wiry and fragile sections of stem below the lowest leaves can be buried. Plants should be at least a foot apart and might get larger with more space. It takes at least two months for dense round heads of common green or red cabbage to mature. Slower varieties are worth growing for their unique flavors.
Since modern cultivars became trendy several years ago, the old fashioned ‘common’ fringe flower, Loropetalum chinense, has become even more uncommon than it already was. It does not grow fast enough to function as large scale shrubbery, but slowly gets too big to work as small shrubbery. Without pruning, old plants take many years to get to fifteen feet tall.
The common name sounds funny, but it is easier to pronounce then than the Latin name. Mulla mulla, Ptilotus exaltus, is an Australian species that has been locally available longer than its limited popularity suggests. It may seem to be more peculiar than it is because it is grown primarily by specialty growers, who happen to grow many cool plants that should be more popular than they are.
If it were not so seriously susceptible to fireblight, the evergreen pear, Pyrus kawakamii, would be a practical evergreen shade tree for small garden spaces. Mature trees do not often get much taller or wider than twenty five feet. Aggressively pruned trees that do not bloom much are less susceptible to fireblight. Regularly groomed trees can live with fireblight for many years or decades.
They are really just smaller versions of the larger perennial dahlias that are grown for their big bold flowers and flashy colors. Technically, annual dahlias produce smaller versions of the same perennial roots that can survive through winter to regenerate the following spring. Yet to most of us, it is easier to purchase new plants in spring than to grow new plants from stored roots.
The most popular hardwood in California is essentially unavailable in nurseries. California black oak, Quercus kelloggii, provides between a quarter and a third of the hardwood timber harvested in California. One would not know it by its sporadic appearance within mixed forests of the Coastal Ranges. It is much more common in the Sierra Nevada, which might be why no one grows it.
Now that they have been so popular for so long, the deficiencies of flowering pear, Pyrus calleryana, (which is also known as Callery pear), are becoming increasingly evident. The dense branch structure and compact form that are so appealing while trees are young compromise structural integrity as trees mature. Symmetrical trees can be severely disfigured if limbs get broken by wind.
‘A Tree Grows In Brooklyn’ documents the resiliency and invasiveness of the common but typically undesirable tree of Heaven, Ailanthus altissima. Once a single female tree get established, the extremely prolific seeds get everywhere, including cracks in concrete. The resulting seedlings conquer wherever they are not dug out. If cut down, they just resprout from the roots.
The first half of the name sound appealing enough. The second half, not so much. Do the seeds grow into snails? Do they just look like snails? Not many have seen them. Tiny pale white flowers that are supposed to bloom in spring, as well as small black berries that develop after bloom, are rare. Laurel-leaf snailseed, Cocculus laurifolius, is grown just for its glossy evergreen foliage.
They sure took their time getting this far along. The bluish green succulent foliage of showy stonecrop, Hylotelephium spectabile, (formerly Sedum spectabile) first appeared at ground level in early spring, and has been growing into rounded mounds so slowly that it now stands less than three feet high and wide. Smaller types are half as big. Blooms are only now beginning to turn color.
