Average Peak Bloom Date: April 4
2012 Peak Bloom Date: March 24 – March 31
2012 Blooming Period Forecast: March 22 – ???
Exactly when the buds will open is not easy to predict and it is extremely
difficult to give an accurate forecast much more than 10 days before peak
bloom. National Park Service horticulturists monitor five distinct stages of
bud development and provide timely forecasts and updates.
The Peak Bloom Date is defined as the day on which 70 percent of the
blossoms of the Yoshino cherry trees that surround the Tidal Basin are open.
This date varies from year to year, depending on weather conditions. The
Blooming Period is defined as that period when 20 percent of the blossoms
are open until the petals fall and leaves appear. The blooming period starts
several days before the peak bloom date and can last as long as 14 days,
however, frost or high temperatures combined with wind or rain can shorten
this period.
Visit the National Park Service‘s website with links to the Blossom Cam,
cherry blossom photos, and information on how to donate to the Cherry Tree
Replacement Fund.
The following is a comparative record of past bud development. The date
listed is when 70 percent of the buds have reached each stage:
Green Color in Buds: Mid to late February – Early March
Florets Visible: Early to Mid March, Av. 16-21 days to Peak Bloom
Extension of Florets: Av. 12-17 days to Peak Bloom
Peduncle Elongation: Av. 5-10 days to Peak Bloom (Frost Critical)
Puffy White: Av. 4-6 days to Peak Bloom
