Why is rose so expensive?

Could you please enlighten me as to why roses command such a high price tag? Is it due to their intricate beauty and the intricate process of cultivation? Or perhaps it's the symbolism they carry, representing love and romance? I'm also curious if the scarcity of certain varieties or the demand for them during special occasions like Valentine's Day contributes to their costliness. Could you elaborate on the various factors that might contribute to the exorbitant price of roses? I'm really interested in understanding the economics behind this popular floral choice.
