Crown daisy grows well in mild or slightly cool climates and bolts to premature flowering quickly in warm summer conditions; seed is sown in early spring and again in fall for a longer cropping window. Leaves, stems and flowers are all edible. Usually fairly pest-resistant, but tender shoots can attract aphids and whiteflies, and young seedlings may be nibbled by slugs and snails, especially in damp conditions.
These source is specific to this region. The full list of 2 sources behind this guide (Royal Horticultural Society, True Leaf Market) is in the references of our UK guide to shungiku; they describe the plant itself, which is the same wherever it grows.
Plan next season before the problems start
This page gives you the thresholds; the planner turns them into your own calendar. It works from what you can observe and measure in your garden rather than from dates written for somebody else’s latitude.

How this guide is put together
The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against international horticultural research and extension sources. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
