Greenhouse flowering time data for serpentine and sandstone populations

Data collected at the Michigan State University greenhouse on serpentine "Serp" or sandstone "Sand" soil in two treatments- "Dry" vs. "Control". 'Pop' indicates the population source, 'Initial Flat' refers to the flat/position of the individual before being assigned to a treatment. 'treatment_flat' refers to the flat replicate (nested within treatment- either 1 or 2). 'Plant' is a unique number for each plant on each flat, 'Date_Planted' is the day that each individual was transplanted, 'Flower_Day' is the first day that each plant was observed to flower (Day 0=first day of transplant/Feb 11), and the first plant to flower was on Day 27 (corresponding to March 10).
