How to sow coriander: Direct seed indoors, transplant seedlings outside after hardening off
Sun requirement for coriander: Plant in Full Sun
Coriander is the English (UK) name for Cilantro. In America, Coriander is used to refer to the dried round seeds of the Cilantro plant, which have a warm, spicy flavor and are used in curries, pickles, sausages, soups, and stews. The essential oil of the seeds is used in herbal remedies and dietary supplements, and to flavor liqueurs, gin, vermouth, tobacco, and perfumes. Cilantro is an annual herb in the Apiaceae family with soft leaves that are broadly lobed at the base of the plant and become slender and feathery higher up the stems. The leaves will be ready to harvest within 50-55 days, the seeds take up to 100 days to mature and then need to be dried.
A plant grows with warmth, not with days. A growing degree day is one day's worth of useful warmth: how many degrees the day's average temperature is above the lowest temperature the crop grows at. Add them up from planting and you know how far along the crop is, whatever the calendar says.
Say that lowest temperature is 10°C. A day averaging 17°C gives 7 growing degree days. A day averaging 8°C gives none, as it is too cold for the crop to grow. That is why the same lettuce takes about 50 days in a summer and 90 in an autumn: it needs the same total warmth either way.
Coriander needs about 60 growing degree days.
For coriander, the FAO EcoCrop database gives a lowest growing temperature of 4°C and a shortest growing cycle of 35 days at its best temperature, about 560 growing degree days to a first harvest.
Where you've told us where your garden is, we use this and the weather there to predict when your coriander will be ready to harvest. We don't use it for how long a plant lives or when it finishes: we go by what members have logged for that.
Only plantings by members who have set their locations are shown.

Something i've been working on is the predictions on GrowStuff.org. If you go to you gardens page there's now a progress bar for each annual planting. That's plantings that are expected to complete there lifespan in 2 years or less . the progress bar is % until the plant is finished a…
