Phenology
The number of days to first flowering significantly varied with germination strategy and was not affected by soil warming (Fig. 1, Fig. 4, Table 1). Although warming did not affect flowering time, it accelerated time to seed maturity and reduced the overall duration of seed production. Immediate germination strategy plants flowered 50 days earlier and the seeds were relatively slower to mature compared to the three other strategies (Fig. 4, Table 1). Consistent with their early flowering date, absolute timing of seed maturity of immediate strategy was earlier compared to the other strategies (Fig 4, Table 1). Finally, the plants senesced earlier in warmer soil than in ambient soil (Fig. 1, Fig. 4, Table 1). At the end of the experiment a greater proportion of plants survived in the ambient than warmed conditions for all germination strategies except the postponed strategy, in which mortality was approximately 95% regardless of growth temperature (Fig 4, Table 1).
