If the Latin name of dwarf periwinkle is Vinca minor, it is logical that large periwinkle should be Vinca major. Large periwinkle is more commonly known simply as periwinkle or common periwinkle, although it is not as common as dwarf periwinkle is, at least in landscapes. In some regions, it has naturalized as an invasive weed.
Some might accurately say that periwinkle is shabbier than the relatively neat and dense dwarf periwinkle. Others might say that it is just rustic or informal. The wiry stems stand less than a foot tall before they bend over from their own weight. Fallen stems can root where they touch the ground, and grow into new plants over winter.
The evergreen foliage is rich green, and a bit darker than the top of a billiard table. The simple paired leaves are about an inch and a half to two inches long. The slightly purplish blue flowers are about an inch and a half wide, with five petals each. Bloom is sporadic, but almost continuous, except for a lapse through winter.
This . . . was a ball field. It might eventually be one again. The old backstop at the upper left corner of the picture is almost completely obscured under a thicket of blackberry brambles and a fallen boxelder. It would need to be replaced. So would the decommissioned irrigation system, all the bases, the basepath, the turf . . . and everything else that goes into a functional ball field.
It has been naturalized in Southern California long enough to seem to be native. California pepper, Schinus molle, is actually endemic to Peru and adjacent arid regions of South America as far south as Central Argentina. Furthermore, although its small pink fruits with hard black seeds are sometimes used for culinary purposes, it is actually not related to black pepper, and is mildly toxic.
Not only does it start to bloom late in summer, but as the name implies, four o’clock, Mirabilis jalapa, blooms late in the afternoon to attract nocturnal moths for pollination overnight. By morning, the white, yellow, variable pink or rarely pastel orange flowers are closed, and their yummy fragrance is gone. Individual flowers often display irregular stripes or blotches of alternate colors, and can be divided into zones that are shaped like slices out of a pizza. Plants get nearly three feet high, but then die to the ground with the first frost. They regenerate from big tuberous roots as winter ends, and can seed profusely.
It is known by a few different common names, including ‘Andean pampas grass’, ‘purple pampas grass’, and simply ‘pampas grass’. ‘Andean pampas grass’ sounds almost like an oxymoron, since the Andes Mountains are in a separate region to the west of the pampas region of Uruguay and eastern Argentina. ‘Purple pampas grass’ is even sillier, since it is devoid of any purple.
