No, Ivy, like most of the Gotham Rogues gallery, is at Arkham. The only reason Freeze was there was to facilitate The Light's plans. The Riddler, being more eccentric then full on insane, would also likely find his way to Belle Reve as opposed to more unstable minded criminals. Honestly, given the vines and forest motif, I think there's a chance it was Earth 16's version of Giganta, one with Super Strength but without her other Universe's ability to grow in size.
