Dates are for the typical city of each climate by the Greenly calendar’s rules: sowing and planting from the last spring frost (frost-hardy plants about three weeks before it, the rest a week after it once the soil is warm), autumn planting a month before the first autumn frost; annuals and summer bulbs flower after the card’s days to the first flowers for the card’s length of flowering, until the first autumn frost; flowering shrubs by the card’s days after the last spring frost. Perennials and autumn bulbs flower once established, so their flowering is not dated here.
