There is a saying “April showers bring May flowers.” The saying, however, doesn’t specify which flowers or what you should do to make the most of that abundant May energy. I suggest turning your attention to flowering herbs, which can be made into healing teas, tinctures, and ointments and, of course, used for magic. Which herbs are in flower will vary depending on where you live, but you can either plant them in your yard or garden on purpose or take a walk and see what has sprung up without human intervention. ( Just make sure that any herbal flowers you pick are safe and readily identifiable.) When you have found some lovely May flowers you wish to use, put them in a vase or bowl on your altar and say this spell:

April showers bring May flowers.
May those flowers bring me
healing and magic and joy.
So mote it be!
