Growing perennials from seed is a rewarding process made more manageable through direct seeding. Direct seeding means planting seeds directly in the ground without first sprouting them indoors or in a greenhouse. Sowing directly in the garden is a space-saver when it comes to seed starting and reduces materials and maintenance.
With flowering perennials, direct sowing in late winter usually entails scattering seeds on a clean soil surface, lightly covering them to nestle in, and letting nature take its course. Many perennials need periods of cold temperatures and moisture for spring germination. This cold stratification exposes seeds to natural freeze and thaw cycles, breaking down the seed coating for emergence in warmer temperatures.
Direct seeding perennials in February allows seeds their required cold exposure in preparation for spring. Sowing outdoors is especially beneficial in cold climates, where late-season snowfall and cold rains provide insulation and moisture. Winter sowing and starting seeds indoors are viable options, too.
For success with direct seeding this month, rely on perennials that naturally reseed in the landscape. Hardy perennials, including natives, bear seeds well-suited to overwintering outdoors. Those requiring cold stratification may emerge stronger for it.
In the fall, when your perennial garden has flourished and gone to seed, collect and scatter them directly or leave them to drop naturally. Stop deadheading flowering perennials in late summer so seeds can set – beneficial for the garden and wildlife as a winter food source.

Feverfew is an old garden favorite due to its bushels of petite daisy-like flowers and their accompanying herbal uses. Blooms last from early summer through frost, and foliage is feathery and aromatic.
This sun-loving plant is easy to grow in moist, well-drained soils. It self-seeds hardily, so pull any unwanted volunteers and deadhead spent blooms to prevent unwanted seeding. Deadheading also proliferates flowering. Use feverfew in naturalized areas where it can reseed freely or in borders and rock gardens.
Seeding feverfew in late winter, a few weeks before the last frost date yields good germination results. Scatter seeds and lightly tamp them in for contact with the soil and exposure to sunlight.
Final Thoughts
Direct seeding in February grants many perennials the cold and moisture cycles necessary to germinate. For best results, opt for flowering perennials that readily reseed in the landscape. Hardy perennials, including natives, produce seeds adapted to overwinter in the ground.
Experiment with seeding on bare, scuffed soil and give a light soil cover. Late-season snowfall insulates the seeds, and cold rains provide moisture. As temperatures warm, seeds germinate and begin actively growing.
Growing flowering perennials by direct seeding brings lasting color, form, and texture to the landscape efficiently and economically. There’s also the element of surprise in seeing what emerges come spring. Delight in seeding your new garden plantings – signs of spring will follow!
