Details

Dahlias from seed are a fun gamble: a mixed bag of colors and forms, blooming the same year you sow. This is a seed-grown dahlia mix (Dahlia x variabilis), grown as an annual.

How to grow

  • Sun: full sun
  • Sow: start indoors 4-5 weeks before the last frost, or direct sow after the last frost once soil is 65-70°F
  • Depth: 0.25 in
  • Germination: 3-5 days at 65-70°F
  • Spacing: 9-12 in
  • Height: 40-60 in for a giant hybrid mix; varies by seed type
  • Days to bloom: 75-90 days from seeding; some sources say about 100-120 days to first bloom

A kind note: the photo shows a bouquet of large, fully double named-variety dahlias. Seed mixes give varied plants, and fewer of them will be fully double.

Why we grow it

A packet of dahlia seeds is a little garden mystery: colors and flower forms vary from plant to plant. These seed-grown annuals can bloom in their first season.

Start inside before the last frost or sow outside after it passes. The bouquet in the photo shows named, fully double dahlias; seedlings from this mix may look different.

Good to know

A few practical answers before you plant.

Will these look like the bouquet photo?

Not necessarily. Seed-grown dahlias vary in color and form, and fewer plants may have fully double blooms.

Can I sow outdoors?

Yes. Direct sow after the last frost once soil reaches 65–70°F.
