Bit by the gardening bug

One of the grad students who works in the same area as me has been bitten by the gardening bug. He stops by from time to time to talk about what he wants to grow, and I've offered some advice on where to get good plants, or to handle some container gardening problems.
He's hit that "LOOK WHAT YOU CAN FIND On THE INTERNET!" stage, and ordered himself some banana plants. Now he's trying to get *me* to order banana plants.
I've tried to explain politely that I don't really have any interest in growing banana plants, even if they, as advertised, will survive outside around here. I'm not getting through, though. He sent me the URL for the banana site, and asks me if I've looked at it yet every time he sees me. All day, he asked me.
I have to laugh. It's fun to see someone else go through that first wild gardening ambition. I'm trying not to squash the enthusiasm by poo pooing all the impossible things he wants to grow on a small apartment patio, but I'm a little bit torn. It's hard to find a balance between offering good advice and being a gloomy old fart who rains on his parade.
It should be an interesting summer.
