The blooms form two separate cupped clusters that meet in the middle, like jaws. Squeeze the sides of the jaws, and the two clusters will separate, just like a mouth opening. Release the bloom and the jaws "snap" closed.

Misc FactsAntirrhinum is from the Greek meaning snout, referring to the shape of the flower
Author's NotesI have tried on a few occasions to grow taller Snapdragons that I purchased in packs. Most of the time, they have small flowers. These plants never reach their stated height. I think it has something to do with the small plants having flowers or flower buds. This seems to stunt their height potential. A solution is to start with plants lacking flowers or flower buds. I grew this Snapdragon in 2022, and it was a great plant. I bought the plants in early June in pacs, and the plants were solid roots. I broke up the root ball and planted them in biodegradable pots, then in the garden, and they took off. Great performers!
