Of these 985 plants, 616 have been checked against outside sources (38 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.
