Several years ago I started taking botanical illustration courses during the slower winter months. Drawing and painting flowers, plants, and even fruits and vegetables, has been a really enjoyable way to stay connected to the beauty of plants during our cold and snowy upstate New York winters.
Whether you are a total beginner or an experienced artist, I highly recommend the online drawing and painting courses offered by Cornell University’s horticulture section. You can learn more about these courses at the homepage for the online horticulture courses here: https://cals.cornell.edu/school-integrative-plant-science/school-sections/horticulture-section/outreach-and-extension/horticulture-distance-learning
There are also many excellent painting tutorials on youtube.
