Hasn't hurt mine over the years.

Wow...never thought of this. It really works? I have noticed that the stamens are removed on florist lilies, but thought that was done to keep pollen from dusting the blooms. I assume this can be done to any type, not just orientals?

There is no evidence to support the notion that removing stamens will increase flower life, not even with cut lilies. Removal of the stamens/pollen holders is done for cosmetic reasons - to prevent the pollen from staining the flowers or from staining any other surface it may come into contact with. Lily pollen is pretty much indelible once it stains fabric or even skin.

And removing the stamens or pollen holders will not affect the plant adversely. Like disbudding or removing the sexual organs of any plant, it just prevents the plant's energy from being directed to seed production, which with bulbs certainly is not a bad thing.

reason: removing stamen reduce synthesis of ethylen by anther

Florists remove it because it stains the flower and fabric.

Do not enjoy getting a phone call from an angry lady with ruined tablecloth....
