If you get anything at all it makes sense that it would be from 4n Asiatic pollen since Tiger Babies are more Asiatic than trumpet. Maybe I'll try that next year.
This reminds me of my 4n orienpet x trumpet crosses. For example using 4n trumpet on orienpet American West I get really huge pods... pods that make me think I hit the jackpot. But I am lucky to find 10 seeds that look like they are good.
