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 249 plants, 99 have been checked against outside sources (20 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.
