Winter and Spring Annual Flowers for Arizona's Intermediate to High Deserts
Flowers blooming in winter brighten barren gardens with delightful color and fragrant delights. These plants withstand some frost and bloom through the winter and spring. Plant these flowers in the early or mid-fall. Check garden centers and nurseries for transplants starting in mid-September. Many of these flowers can be grown from seed, too. Keep seeds or new transplants moist but not soggy until they are established. Use frost cloth or plastic to protect plants from unusually cold temperatures during the winter, if necessary. Plant some flowers for fall and winter color this year.
