The table calls it a tie: Begonia and Blue Salvia share the crown at 100 and 100 of 100, a gap smaller than the data can honestly split.
The gate is brutal on purpose: documented bloom through June AND July AND August, or the flower is out, however famous. What remains is ranked on how much of the whole season it covers, whether it pushes into October, and the upkeep that marathon demands.

How we rank
We keep one table of 85 flowers,
with 25 documented facts each, drawn from university and extension sources. Every ranking is
a published formula worth 100 points; tap any score and it unfolds into the lines that made
it. A flower that does not fit the question is not scored lower: it is excluded, and the reason is
shown. When the table changes, every score and stamp updates itself.
