Biblical garden plants - almond tree and nuts
And Jesus said:
The kingdom of God is like a man who cast seed upon the earth.
The man goes to sleep and rises again the next day, and the seed springs up and grows, but the man does not know how it grew.
The earth bears fruit with out any help from the man, it does it by itself.
First the blade, then the ear, the full grain. But when the fruit is ripened, he takes a sickle and harvests the grain.
