Summer Solstice
June 21, 2009
We celebrated the Summer Solstice with a day in the Catalinas, the big mountain range just north of Tucson. I wanted to look for Golden-flowered Agaves, whose blazing flower spikes are the very essence of Midsummer. Unfortunately, the 2003 Aspen Fire decimated the agave population (and a lot of other things) but we did see a few. This photo (taken from across the canyon) has a flower spike on the far right. The big tree is an oak that has dropped most of its leaves and is waiting for rain before putting out new ones.

Oak and Agave
Molino Basin, one of the lower scenic stops on the Mount Lemmon Highway, is one of the first places I visited in southern Arizona. I saw it within a day or two of my first visit to Tucson, in summer 1991. I still think it’s one of the best places to see some of the desert’s most spectacular and distinctive plants, including saguaros, several oak species, coralbean, Arizona rosewood, pineneedle milkweed, riparian-zone trees (ash, walnut, sycamore, willows, cottonwood), ferns, and many other things. A few miles up the road, Arizona cypresses and other evergreen trees appear, and shortly afterward the desert plants give way to pine forest and ultimately spruce and fir at the top of the mountain. But the zone where the saguaros mingle with desert oaks is my favorite.
Desert Incense
June 2, 2009
The desert is a fragrant place, since many of its shrubs contain aromatic oils. Some of these plants have medicinal properties and are usable for incense. Here are a couple of my favorites:
BRITTLEBUSH or INCIENSO - Encelia farinosa

Brittlebush
A very common small shrub among the saguaros, with triangular leaves that are covered in dense white fuzz. The pale stems are woody but very fragile. They exude beads of sticky golden resin that are a bit tedious to collect, but the wonderful incense is light, airy, and well suited to indoor use. Good for daytime purification work, and even the cats like it. It invokes the clean, arid brightness of the desert morning.

Brittlebush Gum
Along with creosote bush (Larrea tridentata) and seepwillow (several Baccharis species), brittlebush is one of the characteristic unforgettable scents of the Sonoran Desert after a rain. The yellow daisylike flowers bloom in spring, giving way to fuzzy seedheads in high summer. The plants drop their leaves during the dry months and may freeze to the ground in winter, but they sprout new leaves and branches very quickly after a rain. Brittlebush is easy to grow and is popular for xeriscapes. Individual plants usually live for fewer than ten years, but the seeds sprout easily, and a single plant can populate an entire hillside with tidy, rounded gray shrubs within five years. When the dried leafy branches are burned, they give off a creeping smoke that is an excellent mosquito repellent. Tea made from the leaves is good for colds – it is a mild analgesic and decongestant, gently calming but not a sedative.
COPAL, TOROTE, or ELEPHANT TREE – Bursera microphylla

Bursera microphylla
Bursera is a genus of aromatic Mexican trees that are the source for copal resin, which is sold for incense, perfume, and medicine. There are several species, but all Bursera trees have unusually thick, pale, gnarled trunks, which is why they have been nicknamed “elephant trees”. B. microphylla is the only species that is cold-tolerant enough to grow wild in the U.S., where it is restricted to south-facing slopes in a few widely scattered and remote desert mountain ranges in southern Arizona and California. The U.S. plants like the one in the photo are typically large, multi-trunked shrubs, and rarely reach tree size. Young twigs are dark red, older branches have a red and gray netlike pattern, and the stout trunks have pale, papery outer bark that peels or shreds away to reveal the smooth green inner bark. Bright green feathery leaves appear with the summer rains. The entire tree emits an exotic tropical fragrance, and the beads of resing are collected from wounds in the bark. Its scent is strong and complex, but not irritating. Bursera gum is an astringent with many medicinal uses.
When using incense for purification or healing, I employ a primitive form of “smoke divination” during the work. I burn the incense in a tiny forged iron bowl and carefully watch the smoke color and quantity, the direction it moves, any flames that are present, and how easily the incense burns.
Letting in the Light
April 23, 2009
I’ve been sidelined by illness for a couple of weeks, but am back at work now. I looked for ways to restore balance around the house, and decided to cut a window in the door to my studio. I keep the door closed because some of my more primitive cats will spray and wreak all kinds of destruction if they are allowed to enter unsupervised. Now I can keep out the naughty cats and still allow air and light to flow freely. Photo shows the skylight over my desk, viewed from the hall.
