I love the Narcissus plants. They remind me of spring all too well with their white and star like shape! What are your favorite flowers?
Yes! The Narcissus is a genus of spring perennial plants. I also love azaleas which are popular where I live.
Yes! I love the azaleas that have pink where it blossoms but turn into white edges.
The North American azaleas are flowering shurbs in the genus Rhododendron because they have five stamens. I personally just love their beauty. 
I think between Azaleas and Tulips they are the easiest reminders of spring for me. I picture those flowers in my head when people ask me what I think about spring season.
Tulips are so beautiful and a glorious sign that spring blooming perennials geophytes are emerging!
