If I was in this world I'd probably avoid detransforming as long as possible once transformed, due to the ridiculous levels of pain involved in the process. A square per second for maintaining most of them is not so bad especially if ibuprofen and/or Tylenol helps.

What is "enhance" in the secondaries of the pink/yellow and the yellow/pink?
Edit: because that bears on which is a cooler supplement to my preferred Rose, the blue/purple

"Enhance" is vague and might stay ill-defined until I get there, but can be assumed to encompass the same general category of things as video game buffs (speed, strength?) and maybe other things.

Could it include pain tolerance?

Can you use more than one of the same type of flower at a time? Is there any benefit to this if you are not Milan?

This system is not quite straightforwardly self-breaking enough to let you enhance somebody's pain tolerance directly like that.

If you are not Milan, using more than one of the exact same type of flower at the same time does you no good at all. (But doubling up on the pairs, like blue/purple and purple/blue, doubles the relevant boosts.)

Double grace sounds less dramatic than double strength or double senses. Double speed sounds inconveniently unavailable.

Enhance includes providing more temporary versions of the roses' permanent boosts? Does this include temporary flight?

Double grace is less dramatic until you give it to someone who makes good use of it, and then it's terrifying (JokerSherlocks, anyone?)

Undecided on temp flight.

Minor aesthetic tweak: For symmetry reasons, the stems of orange/red flowers are now the same colour as the petals of red/black flowers. (Previously they were a distinct shade of red.)
