Stage BBCH Notes
Planting 0 RHS: plant mid-spring to early summer, spaced 20-30cm (8-12in) apart, or in a container at least 15cm wide by 10cm deep with up to 25% horticultural grit for drainage. NC State: needs under 12in of space given its compact 6-12in height, 1ft width.
Establishment 3 Full sun, free-draining soil (RHS; NC State). NC State: medium growth rate, low maintenance, mounding form with a spreading tendency; nectar attracts bees and butterflies.
Overwintering 0 RHS: most widely sold varieties tolerate UK frost; high-rainfall areas benefit from cloche protection; containers do best in a sheltered spot near a building, in a rain shadow.
Harvest 8 RHS: soft new growth in late spring and summer has the best flavour; harvestable year-round as an evergreen, snipping young shoots whenever needed. NC State: best harvested in the morning, just before flowering.

Every growing guide is checked against RHS, USDA Cooperative Extension, and other named horticultural authorities before publishing. How we check our facts.

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 Canadian hardiness-zone and frost-date data, with provincial agriculture and university extension sources cited directly where one exists for a crop. 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.
