Dahlias (Dahlia spp.) are among the most beloved flowering plants, known for their stunning blooms and wide variety of colors, shapes, and sizes. Dahlias have become a staple in gardens worldwide, admired for their prolonged flowering period and ability to create striking floral displays. Whether grown in flower beds, borders, or containers, dahlias add beauty and vibrancy to any landscape. Dahlias can be grown from tubers, cuttings, or seeds. While tubers are the most common propagation method, growing dahlias from seeds allows for exciting genetic diversity, as seedlings can develop unique flower shapes and colors. Dahlia flowers are a versatile and visually stunning addition to any garden, providing long-lasting blooms, pollinator benefits, and vibrant floral displays. While traditionally grown from tubers, starting dahlias from seed allows for unique and diverse flowers each season.

How to Plant Dahlias from Seed

When to Plant Seeds

  • Indoors: Start seeds 6-8 weeks before the last expected frost.
  • Outdoors: Direct sowing is possible in warm climates after the last frost.

Seed Preparation

  • Dahlia seeds do not require stratification.
  • Use fresh, high-quality seeds for the best germination rate.

Transplanting Outdoors

  1. Harden off seedlings by gradually exposing them to outdoor conditions 1-2 weeks before transplanting.
  2. Choose a sunny, well-drained site in the garden.
  3. Space plants 12-18 inches apart to allow for proper air circulation.
  4. Water thoroughly after transplanting.

Starting Seeds Indoors

  1. Fill seed trays or small pots with moist, well-draining seed-starting mix.
  2. Sow seeds ¼ inch deep, lightly covering with soil.
  3. Maintain a temperature of 70-75°F (21-24°C) for optimal germination.
  4. Water gently and keep the soil consistently moist.
  5. Germination occurs within 7-14 days.
  6. Once seedlings develop 2-3 true leaves, transplant them into larger pots.

Pro Tip

For bigger blooms, pinch off early buds to direct energy into fewer, showier flowers.

Bonus: Dig up and store tubers in winter for years of gorgeous blooms!

Getting to know your Dahlia

Dahlias are versatile plants that can be grown as herbaceous perennials in warm climates or as annuals in colder regions. Their height varies significantly depending on the variety, ranging from a compact 12 inches to an impressive 6 feet. These plants are characterized by their dark green, pinnate leaves and sturdy stems, which support their magnificent blooms.Dahlia flowers are renowned for their incredible diversity in color and shape. They come in a wide array of colors, including red, pink, yellow, orange, purple, white, and even bi-colored varieties. Additionally, their bloom shapes are varied, featuring single, anemone, cactus, pompon, and dinner-plate dahlias, among others. These stunning blooms grace gardens from mid-summer until the first frost.Dahlias, particularly open-centered varieties, are also a favorite among pollinators. They attract bees, butterflies, and other beneficial insects, making them an ideal addition to pollinator-friendly gardens.

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.
