I've been perusing Lapeirousia viridiflora for clues about its pollination. Moth or butterfly was mentioned but nothing definite. It does have a long tube to the nectary. I also see that it can be over 1 foot tall which would help its appeal. It's supposed to smell of clove. One reference I also come accross was an old page from the nursery where this was purchased. It's not on their sight currently. Seem this may have been a supplier mix-up. 🌾
