Misere Hackenbush Flowers

We show that any disjunctive sum of Hackenbush Flowers $G$ has as evil twin $G^{\ast }\in G,G+\ast$ such that the outcomes of $G$ under normal and mis`ere play are the same as the outcomes of $G^{\ast }$ under mis`ere and normal play respectively. We also show that, under mis`ere play, any Green Hackenbush position that has a single edge incident with the ground is equivalent to a nim-heap.
