Keep track of date-based events such as date flower opened for each plant

[playmobil42]

Description of your request
Allow tracking date when a plant first put out a flower bud and when the plant flowered from year to year.

A view showing which plant flowered historically on a calendar would also be nice so one could tell which plants should flower next month.

This allows tracking any repeating developmental stage.

Describe the solution you'd like
Add "events" to each plant, having a date and a tag e.g. on 1.1.2025 flower bud formed, on 1.2.2025 flower opened and free text for each entry e.g. (6 flowers - 3 buds on 2 spikes).

Describe alternatives you've considered
none

Additional context
Related attributes which are valuable:

1. Being able to tell that a given plant flowered one year, then didn't for a couple of years is also valuable.
2. Determining flowering duration by tracking date at which flowers opened and when flowering ended would be nice.
