A lot of people are allergic to pollen and flowers. The traditional Valentines gifts can make them sick regardless if they tell you about the allergies or not. In fact they may have mentioned but you forgot about it.
The best Valentines for someone with allergies is not flowers or candy, what about nut allergies? I personally suffer with allergies and know what those of us with allergies really want for Valentine’s Day. It's not flowers! There is a great alternative that beats flowers every time.
The moment Valentine’s Day rolls around I get a dozen roses. While the sentiment is nice the way I'm going to feel soon after is not. Allergies are no fun and an allergic reaction can hang on for days making you feel really terrible. If you notice the flowers you give to your special someone never hand around long you can bet it's due to allergies.
