The Best Perennial Seeds to Sow in Fall for Gorgeous Spring Blooms

One of the joys of gardening is anticipating the first blooms of spring. By sowing perennial seeds in fall, you can get a head start on vibrant color when the weather warms up again. Many perennials actually prefer being planted in autumn so they can establish roots before winter dormancy. Then they are primed for vigorous growth when conditions improve.

Read on to discover some of the top perennial seeds to sow in fall for stunning flowers next spring and beyond!

Why Sow Perennials in Fall?

Fall is an ideal time to plant many perennial seeds outdoors Here are some key advantages

• Cooler temperatures – Many perennials thrive when sown in fall’s mild temps compared to summer’s heat.

• Natural stratification – Fluctuating cold winter temps naturally stratify seeds, enhancing germination

• Less maintenance – You avoid the need to water newly sown seeds over winter.

• Earlier blooms – Fall-sown perennials get a head start on growth, yielding earlier blooms.

• Bigger plants – With extra time to develop roots before flowering, fall-sown plants are often larger.

Just be sure to sow at least 6-8 weeks before your first expected frost date so seedlings have time to become established.

Now let’s look at some excellent candidates for fall sowing!

Top Perennial Seeds for Fall Planting

Here are some of the best perennial seeds to sow in autumn for stellar performance in spring:

Black-Eyed Susan

A fall favorite, black-eyed Susan (Rudbeckia fulgida) produces cheerful golden daisy-like blooms with dark central cones. It thrives in full sun and is drought tolerant. Sow seeds in fall about 8 weeks before frost for flowers the following summer.

Delphinium

Delphinium produces towering spires in vibrant colors come early summer. To get a head start on growth, sow seeds of perennial types like Delphinium elatum in fall. Cover lightly with soil and mulch well for winter protection.

Lupine

This cottage garden classic sends up gorgeous flower spikes packed with pea-like blooms. Lupine thrives when direct sown in fall—the winter cold helps scarify seeds. Just be sure to choose perennial types like Lupinus polyphyllus versus annual varieties.

Oriental Poppy

The huge satiny flowers of Oriental poppy (Papaver orientale) are a breathtaking spring sight. For best results, sow seeds shallowly in fall and do not cover with soil. The cooling winter temps prime them to germinate when soil warms in spring.

Penstemon

Penstemon produces abundant tubular flowers loved by hummingbirds. Direct sowing in fall allows enough time for these perennials to establish before blooming in late spring or early summer. Go for cold hardy types like Penstemon digitalis.

Perennial Geranium

Sometimes called cranesbill, these mounded plants flower through much of summer with saucer-shaped blooms. Sow seeds of perennial geranium (Geranium spp.) thinly in fall about 8-10 weeks before frost. Plant them where you want them to grow.

Perennial Sunflower

Late summer and fall blooming Helianthus offer cheery color when many perennials are past prime. Sow sunflower species and hybrids like ‘Lemon Queen’ in fall and they will brighten up the garden come late summer.

Pincushion Flower

Another pollinator favorite, pincushion flower or Scabiosa produces clouds of fluffy blooms. Direct sow in fall 8-10 weeks before your first frost for flowers next summer. Scabiosa columbaria is a good fall-planted perennial species.

Poppy

Most poppies thrive when direct sown in autumn versus spring. Lightly scratch the soil surface and sow seeds shallowly—do not cover them. Species like Oriental poppy need this winter chill period to germinate well and produce their famously flamboyant blooms.

Primrose

A welcome early spring flower, primroses (Primula spp.) perform well when sown outdoors in fall. They need a chill period before germinating, so the cooling winter temps prime them for blooming beginning in early spring.

Violet

Charming violets will eagerly self-seed if planted in fall. The hardy winter conditions naturally stratify the seeds for optimal spring germination. Johnny jump ups (Viola tricolor) and tufted violets (Viola cornuta) are good fall planting candidates.

Tips for Fall Success with Perennial Seed

To boost your success with fall-sown perennials, keep these tips in mind:

• Select seeds suited to your zone – Be sure perennials are suited to overwinter in your climate. Select species and varieties with a suitable USDA zone rating.

• Prepare soil well – Loosen soil and remove weeds where you will sow. Rake smooth and mix in compost or fertilizer. Moisten soil before seeding.

• Sow at the right time – Generally aim to seed about 6-10 weeks before the average first fall frost in your area.

• Seed shallowly – No need to bury perennial seeds too deep in fall. Aim for about 1⁄4 inch or lighter.

• Water lightly – Gently water newly sown seeds to help settle soil. But avoid overwatering or seeds may rot over the wet winter months.

• Mulch for insulation – Cover seeded beds with 2-3 inches of shredded leaves, pine needles or straw. This protects from frost heaving.

• Allow self-sowing – Many perennials easily self-sow if you allow some flower heads to go to seed in fall.

With proper timing and care, perennials sown in autumn will flourish and reward you with bountiful blooms starting next spring!
