The big wide medians of San Vicente Boulevard in western Los Angeles had been lacking trees since the Red Car Streetcar rails were removed decades earlier. My colleague, Brent Green, had been wanting to add trees to the medians since he was a little kid, and then became intent on doing so after he became a renowned landscape designer in the region.
At about the same time, I was a nurseryman. In my work, it was not uncommon to dispose of a few items that were unsaleable. Sometimes there were entire crops of unsaleable plants; and in 1997, I needed to dispose of a group of coastal redwoods that had very minor kinks in their trunks.
That gave Brent an idea.
He wanted me to bring some of the trees to Los Angeles to plant them in the medians of San Vicente Boulevard just south of the Miracle Mile District. We were sort of skeptical about their ability to adapt to the climate; but were willing to give it a try, and possibly give the trees a second chance. We planned to install thirty coastal redwoods for Brent’s thirtieth birthday on January 18, 1998.
Well, the trees were not happy there, and did not last long. However, they were the first of what became an annual tradition of planting trees on Brent’s birthday, January 18. The number of trees is determined by Brent’s age for the respective year. For example, we planted thirty coastal redwood trees on his thirtieth birthday, and then planted thirty-one manna gum trees, Eucalyptus viminalis, on his thirty-first birthday, and so on.
After a few more years, there was not much space on San Vicente Boulevard, so Brent started planting street trees in the parkstrips of streets that could use more trees. The original trees in San Vicente Boulevard needed to be removed for the installation of the Metro Rail, but they were nice while they lasted.
This short video is about what the tradition has become now that Brent will be planting fifty birthday trees.
It may not be the biggest or best deciduous shade tree, but European white birch, Betula pendula, is famous for tall and elegant white trunks with wispy pendulous stems. It is a very informal tree that typically leans in one way or another, but is somehow right at home in refined landscapes. It is rarely alone, since it is usually planted with two or more friends, and sometimes in groves.
Of the various specie of podocarpus, and as the name implies, the long leafed yellowwood, Podocarpus henkelii, has the longest leaves. They can get about six inches long, and hang elegantly from upwardly curving branches. This glossy evergreen foliage can be quite dense. It is dark green in full sun, and can be a slightly bluish in partial shade, particularly as new growth develops.
It is no surprise that there are many different types of physicians within the medical industries. Pediatricians, surgeons, cardiologists, dermatologists, and all sorts of ‘doctors’ are all recognized for their particular medical specialty. Yet, almost all horticultural professionals are known simply as gardeners or landscapers, even though many never work directly in gardens or landscapes.
Many arborists mark certain lengths on their pole saws and pole pruners. When stood upright, these marks designate the standard heights for minimal clearance pruning. Not so many need to mark the height of minimal clearance for walkways, since they will prune away anything that is within reasonable reach with hand tools from the ground. The minimal clearance above parking spaces is not so easy to guess at, so is more likely to be marked on poles. So is the minimal clearance over roadways, where the lowest limbs must be high enough to be out of the way of campers and freight trucks.
The big name of this little pine takes some explaining. Domingo pine is a cultivator of an interspecific hybrid of two distinct specie, Eastern white pine, Pinus strobus, and Mexican white pine, Pinus ayacahuite. Until a better name in invented, it is known as Pinus strobus X ayacahuite ‘Domingo’. It is typically but incorrectly abbreviated as Pinus ‘Domingo’, or Pinus strobus ‘Domingo’.
People really stress out over Christmas trees. Some do not want a cut Christmas tree because it involves killing the tree. Some do not want an artificial Christmas tree because it is . . . artificial. Some do not want a living Christmas tree because it is too expensive for a tree that is too small. There are so many myths and misconceptions about Christmas trees, yet everyone wants one.
Many towns display a Town Christmas Tree in a prominent and centrally located public space.
From the same landscape that, last autumn, was so dutifully deprived of its elegantly cascading rosemary and soon to be fiery autumn color of Boston ivy,
