Batgirl # 52 - That Girl is Poison

Batgirl enters the new garden 'artwork' to find out what it is in there which is making people act according to their baser instincts. Here, she is attacked by Barbara Gordon, who explains, once clear of the garden, that it is something in the scent of the flowers that causes this. Batgirl confronts the artist, discovering that Poison Ivy, his 'muse', is behind this, and the garden is spreading. Encountering Ivy, Batgirl throws a flare into one of the central trees, burning it and halting the garden's growth. Batman then arrives, having been held up by JLA business. Life returns somewhat to normal, but the garden is still there.
