When to Start Seeds and Plant Annuals in Oregon: Frost Dates and Hardy Flowers

Petunias vs. Pansies Timing

Petunias are warm-weather annuals—do not plant outside until frost danger is past and soil warms. Pansies tolerate cool weather but fade in summer heat. In Oregon (zone 8-9), hold petunias indoors until April; pansies can go out earlier but may need deadheading after cold snaps.

Shade-Tolerant, Non-Toxic Flowers for Kids

• Impatiens – reliable in shade, non-toxic.
• Sunflowers – many colors (white, chocolate), easy for kids to grow and harvest seeds.
• Carrots – plant a row; kids love pulling and eating them in 7–8 weeks.
• Bachelor Buttons – fastest blooming from seed, vivid blue.
