Sign-ups are open for a G4 Flower Custom Swap at the MLP Arena.
"The main objective of this swap is to create a custom Generation 4 (Friendship is Magic) custom pony using one of the five flowers your secret partner selects.Deadline for sign-ups is April 16, 2011. For more information, visit the MLP Arena thread.
Anything goes, from Amaryllis to Zinnia, so long as it has a visible flower. Plants like Holly and Apple trees are also acceptable, so long as they're in the flowering stage, not the fruit-bearing stage."
