How this list is made
Derived from each plant's bloom months and USDA hardiness zones, as stored in the BloomsEye library, which was written with AI assistance. Of these 276 plants, 157 have been checked against outside sources (16 fully verified); the rest have not been checked yet, and each plant's own page says which. The cards are AI-generated illustrations. Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
The flowers of May in zone 10
Every plant on this page is in flower in May. These are the ones with the shortest seasons around it, ranked by how much of each plant's flowering falls in April, May and June: a plant that opens and finishes here sits ahead of one that flowers from spring to frost, and ties go to the plants this site's guides name most often.
May bloom in zone 10 by flower color
A plant that comes in more than one color is counted under each. The picks rank the same way as the flowers above, so each color names the plants whose season sits closest to May.
