How to Plant Evening Primroses from Seed

When to Plant Seeds

  • Outdoors: Sow seeds in late fall or early spring, depending on the climate.
  • Indoors: Start seeds 6-8 weeks before the last expected frost for earlier blooms.

Seed Preparation

  1. Choose a well-drained, sunny location.
  2. Loosen the soil and remove any weeds.
  3. Scatter seeds lightly on the soil surface and press them in gently.
  4. Do not cover the seeds deeply, as they require light to germinate.
  5. Keep the soil moist but not waterlogged.
  6. Germination occurs within 10-30 days.

Pro Tip

To encourage continuous blooms, deadhead spent flowers—but if you want them to self-seed, let some go to seed in the fall.

Bonus: The fragrant, night-blooming flowers attract moths and pollinators!

Getting to know your Evening Primrose

Evening Primrose is a biennial, meaning it completes its life cycle in two years. The plant is self-seeding, ensuring natural regeneration. It produces bright yellow, four-petaled flowers that open at dusk and fade by morning. Evening Primrose Flowers emit a sweet fragrance and attract nighttime pollinators that blooms from late spring through early fall.

Our Seed Safety Promise

We do not sell genetically modified seeds — ever. And we don’t use genetic engineering to breed new varieties. Instead, our skilled breeders use traditional, natural crossing methods to create hybrid seeds that are healthy, safe, and packed with potential.

Our Seed Quality Guarantee

At Shido, we believe great gardens start with great seeds — and that means quality comes first. Every seed lot we offer is ensure to generate top-notch germination because your garden deserves nothing less.

To keep our seeds at their peak, we run thorough pathology tests at trusted outside labs. When you open a Shido seed packet, you can trust it’s been nurtured, tested, and approved to give you strong, healthy plants from the very first sprout.

Types of Seeds We Offer

Hybrid Seeds (F1)

F1 hybrid seeds are the garden’s high achievers — created by crossing two specially chosen parent plants for superior vigor, uniformity, and performance. We use only traditional breeding methods to produce these powerhouse seeds.

Open-Pollinated & Heirloom Seeds

Our open-pollinated (OP) seeds naturally reproduce through wind, insects, water, or self-pollination. When grown in isolation, they produce true-to-type plants year after year.

Among our OP seeds are treasured heirloom varieties — old favorites that have been carefully passed down for generations. While OP plants can be less uniform than hybrids, we run our Open-Pollinated Project to select the most reliable, flavorful, and beautiful strains. Many are also available as certified organic seeds.

Non-GMO: What It Means and Why It Matters

GMO (Genetically Modified Organism) is created when scientists alter a plant’s DNA in a lab — often by inserting genes from completely unrelated species — to achieve certain traits, like pest resistance or herbicide tolerance. This is a far cry from natural plant breeding.

At Shido, we believe gardening should stay as close to nature as possible. All our seeds — whether hybrid, heirloom, organic, or open-pollinated — are Non-GMO. They’re bred using traditional methods that respect natural biodiversity, giving you safe, wholesome seeds that grow into plants just as nature intended.

When you plant Shido Non-GMO seeds, you’re choosing purity, sustainability, and peace of mind — along with a garden full of flavor, color, and beauty.
