The Sniffer´s Flowers should give effects when in contact with an entity

Currently, the sniffer is a wasted oportunity: it is too hard to obtain the mob for a reward that only consists in two decorative blocks. I think there is an easy solution for this problem: make it so both of the sniffer´s flowers (the torch flower and the  pitcher plants) give effects to entities that touches them just like the wither rose gives wither.

I think the torch flower, as its name sugests, should set things on fire but withouth burning the items; and the pitcher plant should give poison when touched. This would give these flowers a lot of potencial in farms of all kinds.
