How to read a comparison

Every row is a fact from each seed's own profile, lined up so the differences stand out.

  1. Sprouting

    Germination time and temperature

    How many days the seeds take to sprout, and the temperature range they sprout in.

  2. Sowing

    Sowing depth and spacing

    How deep to sow each seed and how far apart the plants should grow. “On the surface” means the seed isn't covered.

  3. Timing

    Days to maturity and life cycle

    How long until the plant is ready, counted from sowing or from transplanting (each value says which). Annuals live one year, biennials two, perennials longer.

  4. Light and water

    Sun and water

    Full sun means 6 or more hours of direct sun a day, partial shade a few hours. Water needs are rated low, moderate or high.

  5. Space and weather

    Containers, frost tolerance and soil pH

    Whether it grows in a pot, with the smallest pot when it's known. Frost tolerance runs from tender (no frost) to hardy. Soil pH 7 is neutral.
