Thank you for volunteering to evaluate this data resource on cut flowers. As you can see, am slowly but surely entering in data as I have time. Not all of the data points are completed as I am continuing to search for research showing bloom size. The stem girth will likely be populated from my own work. Please provide your feedback in the comments at the bottom of the page.
