Garden with Insight v1.0 Help: bolting

Bolting is a great expansion in height of some plants at the time of flowering which makes their flowers more accessible to pollinators. Many biennials form a rosette (in which the internodes are extremely short) in their first year, then expand the length of the internodes in the second year to reach a height many times greater. For example, the main stem of a cabbage plant may be only two inches tall in its first year, but at the time of flowering may be four feet tall (not including the large inflorescence at the top of the stem).
