Lammas growth

Examples of common trees which exhibit regrowth are oak, ash, beech, sycamore, yew, scots pine, sitka spruce, poplar and hawthorn.

This secondary growth may be an evolutionary strategy to compensate for leaf damage caused by insects during the spring.

It differs in nature from spring growth which is fixed when leaves and shoots are laid down in the bud the previous year.

The lammas flush involves newly made leaves.

[2] One or more of the buds set in the spring on the ends of terminal and lateral stems will break, and begin to grow, producing a new shoot.
