Bumblebee on exotic plant

Observation - Bumblebee on exotic plant. Description: This ?queen Bombus hortorum has been visiting our strange plant with giant yellow snapdragon-type flowers and hairy silver leavers (is it a herb of some sort?) for some time but I have not seen any other bumbles attempt to visit the flowers.
