Predicting Peak Bloom
One of the most frequently asked questions in High Park during the early spring is “When will High park’s cherry blossom / Sakura trees bloom?”
Blossoms usually reach peak bloom in late April or early May. As you can see from our Peak Bloom Records, the date varies year by year.
Temperature is important for blossom development. The flowers and leaves of trees have different cooling and heating needs in order to develop. Click on chart to the left to see how temperature and bloom dates correspond.
The blooming period begins when 20% of the cherry blossoms are open and ends when their petals fall. “Peak bloom” starts when at least 70% of the blossoms are open. Once open, flowers last from 4-10 days, depending on the weather conditions.
