There is a berakhah / blessing to be recited upon seeing trees in bloom for the first time in the spring:
ברוך אתה יי אלהינו מלך העולם, שלא חסר בעולמו דבר, וברא בו בריות טובות ואילנות טובים להנות בהם בני אדםBarukh attah Adonai, Eloheinu melekh ha'olam, shelo hissar be'olamo davar, uvara vo beriyot tovot ve'ilanot tovim lehanot bahem benei adam.
Praised are You, Adonai, our God, who rules the universe, which lacks nothing; for God created fine creatures and pleasant trees in order that humans might enjoy them.
As we recited this berakhah together, my thoughts returned to the coming festival. Pesah is heralded by the Earth's return to life, like the royal trumpets that would have been sounded long ago at this time. The trees explode in colorful harmony, and a new year has begun. Happy spring!
Rabbi Seth Adelson
* So called because for Jewish kings, the next year of their reign always begins on Nisan 1, even if they ascended to the throne a day earlier, and it is also the deadline for fulfilling a vow to bring a dedicated item to the Temple in Jerusalem. Neither reason is applicable today, of course; there has been no functioning Temple since 70 CE, when the second one was destroyed by the Romans, and there has not been an Israelite king for nearly 2600 years.
