Petunia axillaris

The white petunia (Petunia axillaris) is a member of the nightshade family (Solanaceae), native to South America. It is a wild relative of one of the most popular flowers in horticulture, the garden petunia (Petunia × hybrida). The white petunia is also often grown in gardens due to its large flowers and strong scent at night time, caused by the volatile compounds benzaldehyde and methyl benzoate. Its genome provides insights into the evolution of the cultivated petunia. The white petunia genome is diploid and has a size of 1.4 Gb.
