About Phenology

A great 19th and 20th century fun project for gardeners was creating a phenology. What is a phenology? It is a record of when something blooms. Gardeners would record in their journals the date and year each plant bloomed. For serious gardeners who wished to create vignettes of several plants blooming at the same time the information was very valuable. After a period of years it was interesting to know whether something was blooming earlier or later that year. Indeed scientists studying global warming are actively seeking out old phenologies to compare with today. It would be greatly appreciated if you can add the date, year, place in the comment section of the wiki for any cultivar you observe. Since there are Irises in bloom every month of the year this information could help one plan a garden that would always have an iris in bloom. For hybridizers it could be helpful in planning their crosses and extending bloom seasons. Enthusiasts of reblooming Irises would naturally profit from such data. As this data accumulates for a cultivar we can have some docents who can organize the data. for a better understanding of Iris bloom seasons.

Citizen Science

Information is being gathered Internationally for all types of biological phenomenon. The USA National Phenology Network is looking for participants to help shape the new Nature's Notebook data collection app.The Chicago Botanical Garden is creating a phenology by way of their Budburst Project.. In the UK the Woodland trust has Nature's Calendar. Certainly the Iris societies of the World could provide data on the Genus Iris. This may be the beginning of such an effort by the American Iris Society. If you would like to be a part of this start adding notes from time to time as to what is happening in your Iris garden.

Questions

• Does it matter where I see a biological event?
  • Yes, your comment automatically records your sign in name and date, But if you making a comment from somewhere other that your home base please include location. Spring moves northward at about 300 miles each week so the dates for a particular cultivar will reflect that in their location.
• Is there any limit on the number of comments
  • No
• Should I report rebloom also to the reblooming Iris Society
  • Yes
• Should I record first bloom AND rebloom in the times they occur
  • Yes, Record each bloom event whether it is first and only, or second, or third. Each on its respective date.

Yes
