The software - called Flowers On Time - was developed from research at Michigan State University and the University of Minnesota, with input from the University of Florida.
MSU Extension reports:
"The software is simple to use and only requires you input the species or cultivar from a drop down menu (65 plants), the standard production time in days from transplant to flowering, and your standard average growing temperature. The model then takes that information and provides you with a table and graph of the estimated days to flower at up to 6F either above or below your 'standard' production temperature."
The software is available at the Floriculture Research Alliance website.
