Our mild Autumn weather is almost a second Springtime, especially for gardeners who live at lower elevations in the desert with warm winters. Plant pretty annuals like carpets in empty flower beds to replace any perennials that have died back. Take care not to disturb the roots of the perennials because they will be back next year.
Or fill pots on your patio to overflowing. At higher, cold-winter elevations it may be too late as the first winter storms have blanketed mountains with snow.
Should you dig up the flower bulbs?
While some people, particularly in the U.K. and New England, dig up their bulbs in Fall, in most of the U.S. southwest it is not necessary. But if you want to add flowers from bulbs, rhizomes and corms to your garden, now is the time to plant to assure yourself of Springtime flowers.
Freesia and Iris are two of our favorites. Both require little water and no attention. The exception, however, are those re-blooming iris that flower in spring and fall which need heavy watering.
The incredibly fragrant Freesia dies back to the ground after blooming; the Iris keeps its leaves and provides an upright structural element in a garden border.
If you already have Iris, split and replant the rhizomes now for double the flowers next year. Do not plant them deep. Simply place them in a shallow trench and cover lightly–deep enough to protect from a freeze if you live in an area with occasional light freezes in winter.
About tulips: yes, you can plant the bulbs, but they really love a damper, milder climate — like the Netherlands or Seattle.
Flowers from South Africa
You may be much better off planting bulbs native to South Africa, such as the freesia-like Tritonia or the Watsonia borbonica, which looks like a miniature gladiolus. The low-growing Babiana is a Sub-Sahara native also worth considering as an edging plant. It looks somewhat like a crocus and does well in a desert garden.
The Gladiolus (Gladiolus dalenii), above, a South African native, is a delicate variation on the large, sturdy upright “glads” of late summer. These bloom in Spring.
One plant that is a joy for so many gardeners in California and the Southwest is the Mexican Bush Sage, Salvia leucantha ‘Midnight’ that blooms twice a year. Unlike re-blooming Iris, the Mexican Bush Sage is not a water guzzler. It naturally blooms in Spring and late Fall. It is a super-tough plant with tall spires of purple or purple and white flowers that stay in bloom through December! One year I even clipped the flower stems and used them to decorate my Christmas tree. Tip: Cut it back to about 8 inches high in January and it will re-grow and bloom again in March.
Happy Thanksgiving to you!
