Product Information
These plants typically reach heights of about 1 to 2 feet, forming compact, bushy clumps. Siberian Wallflowers bloom in late spring to early summer, showcasing their colorful and fragrant flowers. With proper deadheading, they can sometimes produce sporadic blooms throughout the summer.
The plant's foliage consists of narrow, lance-shaped leaves that are generally green, complementing the colorful blooms. Siberian Wallflowers thrive in well-drained soil and prefer full sun. They're relatively adaptable and can tolerate a range of soil types but prefer moderately fertile, well-draining soil.
Siberian Wallflowers are popular in cottage gardens, borders, rock gardens, and as edging plants due to their colorful and fragrant flowers. They're also suitable for containers and attract butterflies and other pollinators. These plants are generally low-maintenance. Deadheading spent blooms can encourage prolonged blooming and prevent excessive self-seeding.
Siberian Wallflowers are valued for their fragrant and colorful blooms, their adaptability to various growing conditions, and their attractiveness to pollinators, making them a charming addition to garden landscapes.

Wildflower Planting Time Based on Region:
Southeast
- Fall, Winter: Sowing wildflowers in Fall/Winter is the ideal time in the Southeast, with October 1 – December 31 being the best dates. The weather is ideal for starting seeds, and seedlings can grow and harden off before frost.
- Spring: A good time to plant wildflowers, especially annual species that flower quickly. Plant after the last frost date when soil temperatures have warmed to around 55°F, typically occurring within a month or so after the final frost of winter; this ensures the seeds can germinate properly without being affected by cold weather.
- Summer: You can plant wildflower seeds in the summer, but the hot sun can dry out the soil and stress your seedlings. Summer is a good time to plant quick-growing annual wildflowers.
Southwest
- Fall: A good time to plant spring wildflowers in the desert Southwest. Fall's cooler temperatures and seasonal rains help seeds germinate. In the mountains, you can plant after spring frosts.
- Winter: In areas that get snow, winter seeding can give seeds an advantage in the spring.
- Spring: A popular time to plant wildflowers in most states. You can plant after the last frost and when the soil temperature is at least 55°F. In warmer climates, you can plant at the end of the rainy season.
- Summer: You can plant wildflower seeds in the summer, but the hot sun can dry out the soil and stress your seedlings. Summer is a good time to plant quick-growing annual wildflowers.
Northeast
- Fall, Winter: The best time to plant wildflowers in the Northeast is in late fall, after the first frost but before heavy snow. This is known as dormant seeding and can take place from November to December. Cold temperatures and damp soil during the winter help wildflower seeds germinate.
- Spring: Plant in early spring, after the ground has thawed and soil temperatures reach around 55-65°F. This is a popular time to plant wildflowers because it's typically rainier, which helps water seedlings.
- Summer: You can plant wildflower seeds in the summer, but the hot sun can dry out the soil and stress your seedlings. Summer is a good time to plant quick-growing annual wildflowers.
Midwest
- Fall, Winter: Plant in late fall (November–December) after the first frost. The seeds will overwinter and germinate in the spring. Fall planting is a good option for cooler climates and can give the seeds an early start in the spring.
- Spring: Plant in early spring (April–May) after the last frost when the soil temperature is consistently above 55°F. Spring is a popular time to plant because the soil is usually moist from rain, and you can see the wildflowers grow right away.
- Summer: You can plant wildflower seeds in the summer, but the hot sun can dry out the soil and stress your seedlings. Summer is a good time to plant quick-growing annual wildflowers.
Western
- Fall, Winter: Plant in late fall (November–December) after the first frost. The seeds will overwinter and germinate in the spring. Fall planting is a good option for cooler climates and can give the seeds an early start in the spring.

Pacific Northwest
- Fall, Winter: Plant in late fall (November–December) after the first frost. The seeds will overwinter and germinate in the spring. Fall planting is a good option for cooler climates and can give the seeds an early start in the spring.
- Spring: Plant in early spring (April–May) after the last frost when the soil temperature is consistently above 55°F. Spring is a popular time to plant because the soil is usually moist from rain, and you can see the wildflowers grow right away.
- Summer: In cooler zones with higher elevation, you can plant wildflowers in late spring to early summer, after the risk of frost has passed. You can plant wildflower seeds in the summer, but the hot sun can dry out the soil and stress your seedlings. Summer is a good time to plant quick-growing annual wildflowers.
