Michaelas thread on Silver Blue was getting pretty long or I would have extended it. I would like to say that the African Hawk moths in SE africa can have very long tongues, so thy like to eat the nectar of plant species with very long corollas like Sansevierias. Read the section on ADULTS on the Wikipedia page link.

Can anyone mention other sansevieria pollinators with any certainty? Sources appreciated.

Here is a link that might be useful: Hawk Moth

I don't believe we have that same month here in Calif. but by guess ants may be able to get into the flower tube and do the job for us. I do get seeds, but not as many in the greehoue. If the plant is left out side it does much better, The seeds seem to taka a long time to germinate. Norma

How about hummingbirds, or bats? Are Sans flowers scented?

After searching, mind you it wasn't exhaustive, I've found little about Sansevieria pollination, not surprising. One article studied ants as a pollinator. The results showed little evidence proving that ants assisted/aided pollination. While the extra-nectary glands are great attractants, the ants themselves did not really *do* the pollinating.

That leaves us with the other pollinators. Sansevieria flowers are fragrant, to one end or another. This fragrance is observed at night, generally. This would cut hummingbirds from the group, as they are in torpor come nightfall.

The night time fragrance and white flowers would indicate an evening/night pollinator. Bats are found to pollinate large, open faced flowers like Cereus and Bombax. The tubular formation of the flowers points to pollinators such as moths, the reward being prodigious nectar.

I might suspect bees could play a part in day time pollination, perhaps an errant hummingbird, or an overzealous ant. But for the greater guess, I would have to say moths.

Not set in stone,
