Cilantro has a short growing season in hot climates and bolts when it is finished growing. Plants grown in mid summer will bolt in only four to six weeks due to the high temperatures. The varieties of cilantro seed that do not say they are slow to bolt will produce the quickest coriander crop. Slow to bolt means the plants will not form seed quickly and are more suitable for the cilantro leaves.

The seeds are tiny and will be loose on the stem when ripe. Place a bag under the old flower stem and cut it off. Shake the stem into the bag and the ripe seeds will fall in. The seeds are best used as soon as possible but can be stored in a tightly sealed container.
