With a focus on water-efficient choices and low-maintenance beauty, these selections make it easy to enjoy a lively, thriving garden all season long.
Cyclamen (Cyclamen persicum)
Cyclamen brings a burst of color to winter gardens with blooms in shades of pink, red, and white. Known for its unique heart-shaped leaves, this plant thrives in cool temperatures and indirect sunlight, making it perfect for December. Cyclamen prefers moist but well-draining soil; water at the base to avoid wetting leaves, which can lead to rot. Hardy to around 35°F, it can withstand Tucson’s mild winter but should be protected from frost.
Geranium (Pelargonium spp.)
Geraniums are a classic choice, offering bright blooms in red, pink, and white that endure well into winter. They thrive in Tucson’s sunny climate, preferring full sun or partial shade. These plants should be watered when the top inch of soil is dry, with less frequent watering in cooler months. Hardy in USDA Zone 10, geraniums may need light protection during frosty nights, but they’re generally easy to maintain and will continue blooming with regular deadheading.
Mount Lemmon Marigold (Tagetes lemmonii)
Named after Tucson’s nearby Mount Lemmon, this marigold species provides cheerful yellow-gold blooms and aromatic foliage. Requiring full sun and well-drained soil, it’s low-maintenance and highly drought-tolerant, making it ideal for xeriscaping. Watering deeply but infrequently helps maintain its health. Hardy to USDA Zone 8, Mount Lemmon Marigold can withstand Tucson’s winter, adding brightness to the garden even in the cooler months.
Pink Fairy Duster (Calliandra eriophylla)
Pink Fairy Duster, a native Arizona shrub, is a stunning option for winter gardens with its fluffy, pink blooms.

This plant requires little water once established and is hardy to Zone 8, tolerating light frosts. Pink Fairy Duster attracts pollinators and adds a desert charm to Tucson landscapes with minimal care.

Rosemary (Rosmarinus officinalis)
Rosemary offers both culinary use and ornamental appeal, with fragrant, needle-like foliage and delicate blue flowers. Preferring full sun, it grows well in Tucson’s bright winter light and needs well-drained soil. Rosemary requires minimal watering once established, making it an excellent drought-tolerant option. Hardy to USDA Zone 8, it can survive Tucson’s mild frost and thrives with occasional pruning to maintain shape and promote new growth.

Citrus trees need moderate watering, particularly during dry spells, but reduce watering in winter to prevent root rot. Hardy to USDA Zone 9, citrus trees are sensitive to frost; covering them or using frost cloth when temperatures drop below 30°F can protect them in Tucson’s colder nights.
Roses (Rosa spp.)
Roses bring classic beauty to Tucson gardens, even in winter, with varieties that bloom well into cooler months. They prefer full sun and well-draining soil. Water roses moderately, deep enough to keep roots hydrated but less frequently in winter. Hardy to USDA Zone 5-10, depending on the variety, roses tolerate Tucson’s winter temperatures and benefit from mulching, which helps insulate roots and maintain soil moisture.
These ten plants not only thrive in Tucson’s December conditions but also offer diverse colors, textures, and forms, bringing beauty and vitality to your winter landscape.
