Why don't pine cones smell pretty?

Pine cones typically don't have a pleasant smell because they primarily contain resin and other compounds that serve to protect the seeds inside from pests and decay. The scent of pine trees is often associated with the needles and the resin they produce, rather than the cones themselves. Additionally, the chemical compounds in pine cones can be more earthy or woody, lacking the floral or sweet notes that are often associated with pleasant fragrances.
