Understanding Your Arizona Growing Zone
Arizona spans multiple USDA hardiness zones. Low deserts like Phoenix are zone 9b to 10a. Higher areas like Prescott are zone 7a to 8b. Flagstaff is zone 6a. Your planting dates shift based on elevation.
Check your local frost dates before planting. In Phoenix, the average last frost is mid-February. In Flagstaff, it can be late May. Adjust your flower choices accordingly.
For low deserts, February is prime time for cool-season annuals. For high deserts, wait until March or April for tender flowers. Always protect young plants from unexpected freezes with row covers.
Cool-Season Flowers For February Planting
Cool-season flowers thrive in Arizona’s mild winter temperatures. They bloom best when nights are between 40 and 60 degrees Fahrenheit. February is perfect for setting them out.
These flowers tolerate light frost and need less water than summer varieties. They provide color from late winter through early spring. Here are the best options:
Snapdragons (Antirrhinum)
Snapdragons come in tall, medium, and dwarf sizes. They bloom in shades of pink, red, yellow, and white. Plant them in full sun to partial shade. They need well-draining soil.
Space plants 6 to 12 inches apart. Water deeply once a week. Deadhead spent blooms to encourage more flowers. Snapdragons attract bees and hummingbirds.
Pansies (Viola X Wittrockiana)
Pansies are classic winter flowers. They have large, cheerful faces in many colors. They prefer cool weather and partial shade in hot afternoons.
Plant pansies in containers or garden beds. Use rich soil with compost. Water regularly, but avoid wet leaves. Remove faded flowers to keep plants blooming.
Calendula (Calendula Officinalis)
Calendula is a tough, easy flower. It blooms in orange and yellow. It self-seeds readily, so you get more plants next year.
Plant seeds directly in the ground. Cover lightly with soil. Water gently until seedlings appear. Calendula tolerates poor soil and light frost.
Sweet Alyssum (Lobularia Maritima)
Sweet alyssum forms a low carpet of tiny white, pink, or purple flowers. It smells like honey. It works well as a border or filler.
Sow seeds directly or buy transplants. Space 6 inches apart. It blooms best in cool weather. Trim back after flowering to encourage new growth.
Larkspur (Consolida Ajacis)
Larkspur grows tall spikes of blue, pink, or white flowers. It looks like delphinium but handles heat better. It self-seeds easily.
Sow seeds in place in February. They need light to germinate, so don’t cover them deeply. Thin seedlings to 12 inches apart. Provide support for tall varieties.
Warm-Season Flowers To Start In February
Some warm-season flowers can be started indoors or planted late in February in low deserts. These need warm soil and no frost risk. Starting them now gives you a head start on summer blooms.
For high desert areas, wait until March or April. For Phoenix and Tucson, late February is safe if no frost is forecast. Use frost cloth if needed.
Marigolds (Tagetes)
Marigolds are heat-loving annuals. They bloom in yellow, orange, and red. They repel nematodes and other pests. Plant them near vegetables.
Start seeds indoors 6 weeks before last frost. Or sow directly in warm soil. Space 8 to 12 inches apart. Water at the base to prevent mildew.
Zinnias (Zinnia Elegans)
Zinnias come in many colors and sizes. They bloom from summer until frost. They attract butterflies and hummingbirds.
Sow seeds directly after soil warms above 60°F. In low deserts, that’s late February. Cover seeds lightly. Thin to 6 to 12 inches apart. Water deeply but infrequently.
Cosmos (Cosmos Bipinnatus)
Cosmos have delicate foliage and daisy-like flowers. They bloom in pink, white, and purple. They thrive in poor soil and full sun.
Sow seeds directly in February in low deserts. They germinate quickly. Thin to 12 inches apart. Deadhead for continuous blooms. Cosmos self-seed readily.
Petunias (Petunia X Hybrida)
Petunias are popular for containers and hanging baskets. They bloom in many colors. They need full sun and regular water.
Buy transplants in February. Space 12 inches apart. Use well-draining soil. Fertilize every two weeks. Pinch back stems for bushier growth.
Bachelor Buttons (Centaurea Cyanus)
Bachelor buttons are drought-tolerant annuals. They bloom in blue, pink, white, and purple. They make excellent cut flowers.
Sow seeds directly in February. Cover lightly. Thin to 8 inches apart. They prefer cool weather and stop blooming in summer heat.

Soil Preparation And Planting Tips
Good soil preparation makes a big difference. Arizona soil is often alkaline and low in organic matter. Improve it before planting.
Follow these steps for success:
- Test your soil – Use a home kit or send a sample to your local extension office. Know your pH and nutrient levels.
- Amend the soil – Mix in 2 to 3 inches of compost or aged manure. This improves drainage and fertility.
- Add fertilizer – Use a balanced, slow-release fertilizer like 10-10-10. Follow package rates.
- Prepare beds – Loosen soil to 8 to 12 inches deep. Remove rocks and weeds. Rake smooth.
- Water before planting – Moisten the soil a day before setting out transplants. This reduces transplant shock.
- Plant at the right depth – Set transplants at the same depth as their pots. Firm soil around roots.
- Water after planting – Give a deep watering immediately. Keep soil moist for the first week.
- Mulch – Apply 2 to 3 inches of organic mulch. This conserves moisture and moderates soil temperature.
Watering Guidelines For February
February weather can be dry and windy. Water needs vary by plant type and location. Follow these general guidelines:
- New transplants need water every 2 to 3 days for the first two weeks.
- Established cool-season flowers need water once a week.
- Warm-season flowers need water every 4 to 5 days if planted late February.
- Perennials need deep watering every 7 to 10 days.
- Check soil moisture 2 inches down. If dry, water.
- Water early in the morning to reduce evaporation and disease.
Common Mistakes To Avoid
Even experienced gardeners make mistakes in February. Avoid these common issues:
- Planting too early – In high deserts, wait until frost danger passes. Use frost cloth if needed.
- Overwatering – Cool weather means less evaporation. Let soil dry between waterings.
- Ignoring microclimates – South-facing walls are warmer. North-facing spots are cooler. Plant accordingly.
- Skipping soil prep – Poor soil leads to weak plants. Always amend before planting.
- Choosing wrong varieties – Some flowers need long days or high heat. Read plant tags carefully.
- Forgetting to harden off – If you start seeds indoors, gradually expose them to outdoor conditions over a week.
