Every row is a fact from each seed's own profile, lined up so the differences stand out.
Germination time and temperature
How many days the seeds take to sprout, and the temperature range they sprout in.
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.
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.
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.
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.
Toxicity to cats and dogs
Whether the plant is toxic to cats and dogs.
Quick wins
Days from sowing until the first shoots appear, in good conditions.
Pet friendly
Listed as non-toxic to both cats and dogs. Each seed's page has the details.
