Could it be something as simple as blocking their usage to keep older devices from 'sprite overload'? Both plants have a potential for adding tremendously to the sprites on screen which can slow down things onscreen with lag. This has happened with me in the case of Gold Leaf - I have an older iPad and I have noticed this on my device when the screen gets full of Gold Tiles and Imp Porters/dragonflies. Maybe they wanted to limit their usage for this reason.
