A hand-drawn fern leaf with a botanical illustration style. Inspired by a summer trip to the lush green park trails in Oregon. Ferns are a delicate yet adaptive plant that has many species thriving all over the world. They are one of the oldest known plants to show up in fossil records. Mostly found in humid and tropical climates, there are even some smaller slow-growing varieties living in arid conditions. This fern is about 3.5 inches long.
