have any of you ever experience this?  I received in the mail, 2 cuttiest, well packed leaves of Hardy Chicago. The leaves, very green- look like young ones were cut slanted right at the base without any soft or hard wood (of  standard cuttings) Would I be able to root a leaf?  Has anyone tried this? Do I treat it the same (wet and poting mix?)  I am a bit at loss. Please, any input is greatly appreciated.

No going to happen.

Who sent you just leaves?

that is what I thought! For the sake of the experiment, my window has room, so I will try. 

a person who was selling them in a nearby town... lot of effort and care into the packaging- hate to see them fail.  I have to ask him how he does...

This has been discussed at great length in the past, and creeps up once a year or so. Same problem with trying to grow trees from a root - you might get roots on a leaf (some claim you can), but without trunk tissue/cells, no plant. Some plants like Coleus are capable of this, but nobody we've seen here or at GW has been successful.

Forget all, all about it - F.carica mission impossible...
(less some very, very HIGH tech trick not still/yet available/simplified/proven to us average Joe/Jane's).

Succulent African Violet leaves do very well there (plain leaf rooting)....

Some do mention the 'tissue-culture' term too (not sure there) - but that is beyond my means.
