dormant (resting) axillary and adventitious buds which are used for spring regrowth or replacement of shoots during a season; renewal buds usually form a small proportion of the buds on a plant, their location is species-specific and similar in plants with the same morphology; their location is used in the definition of Raunkiaer’s life-forms and their development is seasonal; in comparison with regenerative buds, structures in the renewal buds are usually more preformed, and may include leaves, stems and in some cases even flowers; their dormancy may be broken by a disturbance, however, this often results in flower abortion or malformation; in many plants no sharp distinction between renewal and regenerative buds exists; the renewal buds together with regenerative buds form a bud bank
