Update:Wow, I am surprised that nobody got this one. It is a pomegranate tree (rimon in Hebrew). This is how it looks in the flowering stage. Some of those flowers will become full fledged pomegranates.
The pomegranate is one of the "seven species" that the land of Israel was praised for:
(Deuteronomy Chapter 8):
And thou shalt keep the commandments of the LORD thy God, to walk in His ways, and to fear Him. For the LORD thy God bringeth thee into a good land, a land of brooks of water, of fountains and depths, springing forth in valleys and hills; a land of wheat and barley, and vines and fig-trees and pomegranates; a land of olive-trees and honey; a land wherein thou shalt eat bread without scarceness, thou shalt not lack any thing in it; a land whose stones are iron, and out of whose hills thou mayest dig brass. And thou shalt eat and be satisfied, and bless the LORD thy God for the good land which He hath given thee.This fruit is also plays a role in many midrashim:
"Did the pomegranates blossom yet?" [in the Song of Songs] - this refers to the young children who sit and learn Torah. They sit in rows like the seeds of the pomegranates. (Shir HaShirim Raba, 6, 17)
And of course there is this famous midrash:
Anyone who has ever eaten this exotic fruit is well aware of the extraordinarily large number of seeds it contains. King Shlomo’s comparison (Shir Hashirim 4:3) of this fruit to the Jewish people leads our Sages to finding merit even in those Jews whose standard of observing the mitzvot leaves something to be desired.
In one place (Berachot 6a) it is explained that the city of Tiberias is also called Rakat because the word raik means empty or unworthy. Just as in the above-mentioned passage we read the word rakota’ich as a hint to “the unworthy ones being as filled with mitzvah credits as a pomegranate is filled with seeds”, so too were even the unworthy people of Tiberias filled with mitzvot.
In another place (Berachot 6a) this appreciation of Jews is extended to the entire nation. Even the unworthy ones, our Sages tell us, are so filled with mitzvot like the pomegranate is filled with seeds that these merits will protect them against the fires of retribution in the World to Come.
