Hi Everyone!

The Chameleana flowers are definitely long-growing - this is to ensure that there's plenty of time for casual players to complete the challenge without feeling too rushed.

However I deliberately ensured that there's no special reward attached to harvesting them, so don't feel you need to wait - you can just discard them if you wish after completing the challenge (or store the rainbow one in your greenhouse, if you have one, so you can attract Chameleons at a later date if you wish.)
