Well, that's just an almanac entry, and the almanac entry only refers to only one member of the certain species. What if the plant you planted is actually on the opposite gender? You plant plants with seeds, not with a cloning device.

As for zombies (excluding Zomboss, because there's obviously only one of him), ditto for the almanac entries. There was no mention of any cloning device, so it's safe to say all zombies have different characteristics, like all plants have different characteristics. Anyone can be bald. Women can grow beards, and men can have long hair and have girly hairstyles if they wish.
