The natural rhythm of plant germination and growth in the wild is represented in the planting program of the Garden.

Because some annual plants are unable to retain a sustainable seed bank in the soil of the Garden we re-seed them each year in the nursery. Other annuals, however, have a much stronger germination capability, due to larger seed size or a better germination rate. These will overcome the surrounding competitors and can be sown directly in the flowerbeds; they include: Lupinus pilosus, Lathyrus cassius, Cerinthe palaestina and Lomelosia prolifera. They will be sown in the Garden following the next rains and a drop in temperature.
