Both are April birth flowers, but Daisies and Sweet Peas look, smell and symbolize differently. Daisies have a traditional white flower, symbolizing innocence, hope and purity. Sweet Peas, however, are colorful, fragrant flowers used to express thankfulness, friendship and happy memories. Daisies are selected for their classic simplicity, and Sweet Peas for their sweet fragrance and fine appearance. It's important to be aware of these differences so you can choose the flower that will best suit the emotions you want to convey or the recipient's personality.
