calyx - calyces (pl) (I just checked it on google - it helps my aging brain to use internet as a prop).

First - my congratulations - "Lava Flow" is one gorgeous columnea.

Second - why it didn't take -

a. it is a hybrid - and sometimes their fertility is low to none

b.try again - be sure that the pistil is receptive - should be kind of glistening with moisture on the best time - usually pollen and pistil are not ready in the same flower at the same time - you need to take pollen from another flower. After you applied pollen to the pistil - try to create high humidity to help the pollen hatch - put your plant under the dome for a week or 2.

Pistil is receptive for short time, pollen actualy lasts, so people exchange pollen in a mail - somebody will take the anthers with pollen , make a small envelope out of shiny newspaper ads to hold them - and just send it to you in a regular mail. i think it stays fresh in a fridge for a long time.

There is a gesneriad club in Ohio - you can check on chapters. Probably there are people in this club who grow variety of Columneas and there are 5 AV clubs in Ohio - check on AVSA.org under Affiliates
- I am sure after several calls you can find several fellow Columnea lovers not far from you.

Good Luck

PS Columnea species make berries for me on their own - but I didn't see one on hybrid.
