It is said that here in Albuquerque we have two seasons: day and night. There is some credence to this saying, for here the temperature differential is 30 to 40 degrees. Check out this weeks temperatures: Today’s high of 91, low 55. Thursday: 82/50. Friday 29/53. Saturday 95/53. Some days there will be a 50 degree differential, such as some days in the winter where days are near 60 but a cold front comes in and the night drops into the teens. Right now, the days are hot enough to blister your hands on the steering wheel, and the nights are cool enough to need a sweater or an extra layer if you are spending time outdoors. There are days when the heat comes on in the morning and the air conditioning comes on in the afternoon. It makes “dressing in layers” a way of life.
The cool of the early morning before the sun comes up is for me the most enjoyable time of the day, those few precious minutes when it is light enough to see the landscape, and cool enough to walk around the garden. But soon the sun arrives like the fierce god that the ancients described, the rays gliding over the mountains in an inexorable progression. It is like the slow motion nuclear blasts that you see in the movies. I see the shockingly intense brightness first hitting the hills in the distance and feel like screaming madly, “IT’S C-O-M-I-N-G!” in the long drawn out wail of a character in an Indiana Jones movie when the wave of bugs are coming to overcome and devour any stragglers. I think about the science fiction movies where people have colonized the planet Mercury, and live constantly moving, in the inhabitable zone between the deep cold of the night and the molten inferno of the day.
The evenings are pleasant as well, with the warm walls of the buildings and a cool breeze. But temperatures don’t moderate until well after the sun has gone down, and I’m not fond of outdoor lighting. In the winter, there is the opposite effect of my summer mornings, where the afternoons are the most pleasant, but the doom of night lies ahead. In those moments, I dread the dark night of Moria.
But the description of Albuquerque as a land with two seasons is not apt for the gardener in me. I define seasons by the times when I can plant, and grow things, particularly when plants are actively growing and blooming. Given this criteria, Albuquerque has four seasons: two growing seasons, and two non-growing seasons, alternating. There is the spring growing season, and following this, the summer doldrums when it is too hot to plant, too hot to grow much (except peppers, eggplant and melons), too hot to spend a lot of time in the garden, and too hot for many blooms. With the onset of the heat, the flowers of many plants wither and drop, the plants entering a semi-dormancy to conserve water, waiting until the cooler days of fall, or at least the moisture from the late summer monsoons.
My penstemon linarioides is like this, the flowers appearing fairly reliably during the last week of moderate temperatures, but withering when that first day over 90 degrees hits, and in the last few days I’ve sadly watched the once enthusiastic blue being sapped of strength, the shriveling. Watering helps, but that ruins the point of my no-water garden. Although the desert willow (Chilopsis linearis) leafs out late (in late May this year), it blooms off and on the rest of the summer with irrigation or supplemental water such as being sited in a swale. Without, it too comes to a halt awaiting monsoon rains. Agastache too, can bloom through the heat, though it only blooms lackadaisically without adequate irrigation. Without an even amount of water, my plants tend to die out or produce blind stems.
Lavender blooms when the heat first hits, the growing stems drooping in the heat, springing back to life once the sun is off the stems. With a bit of irrigation, some varieties such as ‘Provence’ bloom continuously the rest of the summer in my garden, needing some meticulous dead-heading to keep the plant looking fresh.
Chocolate flower (Berlandiera lyrata) blooms, with its deliciously scented yellow flowers, throughout the summer and manages the heat by closing its flowers when the day’s heat begins, and reopening as the temperatures drop in the evening. The hawk moths love the flowers on the Salvia pachyphylla which appear in early summer, and continue on some plants through to fall.
These flowers are bright spots in the garden, which has to hold its own primarily by the structure of plants and textures of leaves. It is a wise thing to have such structure, to provide pleasure and have some sense of life not only through the summer, but through the winter, which lacks even a few spots of bloom, and which always seems too long.
