Plants reproduce by passing pollen from one flower to another, so we can say that all plants can cause allergies to plants, flowers, trees, herbs, shrubs, etc.

Juniper is a plant that releases pollen from the wind, especially in February and March, which is why people with allergies can suffer from what is called “hay fever.” You have to be careful with the symptoms because many people mistake it for a cold but it really is a pollen allergy.
