Random Fun facts with Mia

The oldest plants in our experimental plots are turning 25 years old this year. Happy almost birthday to them! I set off on a mission to determine how many of these plants are still alive so we know how much cake we need to celebrate. These plants are in the oldest portion of our oldest experimental plot (exPt01), they were planted in 1996 and every year since we have visited each plant and recorded various traits.

The first year that these plants flowered was in 1999, a total of 10 plants flowered in this first year. If we look at survival as of 2019 only 251 of the original 646 plants are still alive. Of these 251 surviving plants five of these plants have never flowered! They have been alive for 26 years and never flowered, they have only been producing basal rosettes (just leaves nothing else), all these years. On the other end of the flowering frequency spectrum, one plant has flowered during 16 of the 26 years that it has been alive, that is a 62% flowering rate. To show the high variation in flowering frequency I made the following histogram, the majority of plants have flowered a total of nine or four times.

As I continue to work through the 2020 data from our experimental plots I will be posting more “Random Fun Facts” with Mia so stay tuned to learn more about what is going on in the experimental plots!
