PLEASE, don't list the genders of the plants! While the Suburban Almanac does occasionally state the genders of plants, it doesn't for others, leaving plants without genders, ergo, something for random people to make up.
So, don't post plants genders.
Additonal note: The only zombie with a gender is Dr. Zomboss because he is a single entity. For plants which the Suburban Almanac gives a gender, said gender refers to a single plant out of the entire species, so it does not necessarily apply to the plant variety as a whole. However, trivia (on the plant's page only) mentioning that the Suburban Almanac has a gender for that plant is allowed. --Swampertrox
