I had the exact same idea as you, but I live on a different continent from anywhere that someone I know might have meyer lemon. So I got a friend in California to send a couple of Meyer lemons to me when I was in the USA in August. I took out the seeds, and took them with me to India, and stuck them in the soil of some houseplants. Several germinated within 2 months, and a couple more have germinated now that the weather is warming up.
I know that they won't come exactly true to the parent, but I am hoping that they might
be nice small trees that might give some kind of nice citrus. I'll keep one or two in pots to move in and out seasonally. If I get a few established, I'll try one in the ground in my
greenhouse, which does go down to -5C every night for at least 2 months of winter, but over 0C every day. It might not last, but I'm eager to try anyway.
