taken toronto nursery
Thank you for contacting Toronto Master Gardeners about the identification of this plant. Although it is not possible to provide a specific identification, it would appear to be of the morning glory (Ipomoea genus) family with its fused petalled flower and heart shaped leaves. Since this is a very large plant family, free plant apps are available online and, with a clear in-app photo, may be helpful to obtain a more accurate ID. The nursery staff would likely be able to confirm its specific ID. If you require further information, please submit a query to ASK with as much info. as possible using the criteria listed in the above plant apps link.
Wishing you the best in your quest to identify this plant
