Identification: I think one of these is a tamarillo, no idea what the other one is.

Can anyone help me?

 

First one looks like a Babaco or possibly a fig of some sort. Can you take a picture of the trunk?

I'm not sure quite what the other is, but I can tell you definitively that it's not a Tamarillo. Those have a very sturdy trunk even when young, and the new growth comes out a sort of burgundy colour.

 

First one reminds me of Papaya.
Carica papaya appears to be related to Babaco.

 

Same overarching family, although Babaco is a naturally occurring Vasconcella hybrid, and papayas belong to Carica after the recent taxonomic shuffle.

Looking more closely at the second plant, I'm wondering. If that's a vine, you could have a Granadilla (Passiflora ligularis).

 

I think the first one IS a papaya. I do remember planting papaya seeds now. Thanks!

And, the second one could be a Granadilla. I can't remember if I planted seeds from that fruit.

Thanks!!

 

Gently crush a bit of one of the leaves of the supposed Granadilla. It will smell vaguely passionfruity if that's what it is.
