I have an old (at least 15 years old) and rather large hosta that I'm trying to put a name to. Can't remember where I got it from but it could have been Canadian Tire. The leaves are large and the plant itself is about 1/2 m high. When it first appears in the spring the leaves are white with irregular green edges but as the season progresses lighter colored green "splotches" appear and the white changes to yellow. The plant is actually quite beautiful as it can have 3 or 4 different shades of green at one time. By mid to late summer the leaves have changed entirely to a single shade of green, as the last photo shows. I personally call the plant "Picasso" but would like to determine which cultivar it is. Any assistance would be appreciated. photo taken May 23, 2022....................photo taken June 6, 2022 photo taken July 2021....if you look closely you can still see some variation in color on the left center leaf.
