When to sow tickseeds

Yellow daisies over a very long season on a plant that asks for nothing. The large-flowered kinds are short-lived; the threadleaf types persist for years.

Start seed indoors

8 weeks after

Counted from your last spring frost.

Plant out

2 weeks after

Counted from your last spring frost.

Sow direct

1 week after

Counted from your last spring frost.

Those weeks become real dates once you name a place.

Timing, in frost-relative terms

Seed packets rarely give calendar dates, because a date that suits one latitude is wrong at another. They give offsets from the last spring frost instead, and those offsets are what make tickseeds plantable anywhere.

  • Start seed indoors 8 weeks after the last frost.
  • Plant out 2 weeks after the last frost.
  • Sow direct 1 week after the last frost.
  • Expect a first worthwhile crop in year 1 after planting.
  • Hardy in USDA zones 4a–9a.

Getting the timing right

Plant out or sow direct after the last frost. Shear the plant back by half when flowering slows in midsummer for a second flush that lasts to autumn. Deadheading is what keeps it going, so a neglected plant simply stops.

Frost tolerance

Hardy to -25C, though the large-flowered forms often behave as biennials in a wet winter and are worth resowing. Needs good drainage.

Classified as hardy, with damage expected below -25°C (-13°F).
