Bael
Srimad-Bhagavatam
SB Canto 4
Because Lord Śiva is always very, very merciful, his name is Āśutoṣa. Amongst all the demigods, Lord Śiva can be pacified even by the lowest class of men, who need only offer him obeisances and leaves of a bael tree. Thus his name is Āśutoṣa, which means that he is pleased very quickly.
SB Canto 8
O King, wheresoever on the surface of the globe fell the semen of the great personality of Lord Śiva, mines of gold and silver later appeared.
Śrīla Viśvanātha Cakravartī Ṭhākura comments that those who seek gold and silver can worship Lord Śiva for material opulences. Lord Śiva lives under a bael tree and does not even construct a house in which to dwell, but although he is apparently poverty-stricken, his devotees are sometimes opulently endowed with large quantities of silver and gold. Parīkṣit Mahārāja later asks about this, and Śukadeva Gosvāmī replies.
