FRUITS FLOWERS and GREENS

It is a custom in many communities to adorn the Synagogue and home with fruits, flowers and greens in honor of Shavuot.

Reasons for:
Fruits: In the time of the Beis HaMikdash (Holy Temple), may it be rebuilt speedily, the first fruits were brought to the Beis Hamikdash, beginning on Shavuos.

Flowers: Our Sages taught that although Mt. Sinai was situated in a desert, in honor of the Torah the desert bloomed and sprouted flowers.

Greens: Our Sages taught that on Shavuot judgement is rendered regarding trees in the field.
