April Wild Flower Records
Hamilton, Ontario, Canada
Updated to April 30, 2009

I am updating Latin names from "FLORA Ontario – Integrated Botanical Information System"
as I find errors in my older records.
Here are records of 105 wild or naturalized species and 27 cultivated species found in bloom
in April during the last 11 years in the Hamilton Area.
