Most plants have a postgermination juvenile phase in which flower induction will not occur. Some species require a cold period for flower induction and will not respond to the cold treatments during the juvenile phase. We determined juvenile phases of  Coreopsis grandiflora  `Sunray',  Gaillardia grandiflora  `Goblin',  Heuchera sanguinea  `Bressingham', and  Rudbeckia fulgida  `Goldsturm'. Plants were exposed to 5C for 0, 10, or 15 weeks when  Coreopsis  had 0, 2, 4, 6, 8, or 10 leaves (&gt;1 cm);  Gallardia , 4, 8, 12, or 16 leaves;  Heuchera , 8, 12, 16, or 20 leaves;  Rudbeckia , 5, 10, 15, or 20 leaves. Plants were grown under a 4-h night interruption lighting (LD) or under a 9-h photoperiod (SD) after cold treatments. Based on time to flower and final leaf count, the juvenility of  Coreopsis, Gaillardia, Heuchera , and  Rudbeckia  ended when they had about 6, 10, 12, and 15 leaves, respectively. Cold treatments were necessary for flower induction of  Coreopsis  and  Heuchera  and they increased the flowering percentage of  Gaillardia  and  Rudbeckia .  Heuhera  was a day-neutral plant,  Rudbeckia  was on obligate LD plant, and  Gaillardia  and  Coreopsis  were quantitative LD plants.
