I collected the data by walking around my property once a week, every week and marking what I saw. I break each month into 4 weeks, which I know is not a perfect system but works well for my purposes.

I record this data with a marker in a handwritten notebook, but have input the information into Google Sheets for sharing purposes. This year I've linked each species to a page about that plant so when there is confusion about exactly what the common name refers to, it's clear.

I created and started using this chart with the goal of having the longest possible flower season without any breaks. The data has proved really helpful as a gardener not only for filling gaps, but also for easing my mind when I say "BUT WHERE ARE THE CROCOSMIA?!" and I consult my data to see that on average, they will come up a week from now.

This is the 5th year I've created this chart and shared it in some form on Reddit. I didn't start putting the data into Sheets until last year.

  1. This is amazing, thank you for sharing!! But same question as the other commentor: roughly what part of the world are you in? I’m 52° North and have a feeling you live somewhere similar, or a bit warmer. I’d like to corrolate it a bit with my own garden plants, and we share a lot of them. 😉
