Department of Occupational Dermatology, Free University Academic Hospital, Amsterdam.


The irritant and allergenic properties of the most important flower bulbs are described, as well as the clinical symptoms they cause. The tulip contains the allergen tulipalin A; sensitization and irritation are responsible for the development of tulip fingers. The same clinical picture can be caused by Alliums like the onion and garlic. The narcissus causes lily rash, a dermatitis rarely caused by sensitization. The hyacinth evokes itching in practically everyone: an irritant reaction caused by calcium oxalate crystals. Patch testing is complicated as the allergens are not all identified.
