Each winter, I bring in:
Mango
Lychee
Longan (lychee-relative with small, smooth skinned fruit)
Oranges with 3-4" thorns
Figs
The only one of those I’ve fruited indoors are figs. I’ve also gotten blackberries and strawberries indoors, though not all that many.
Of the first 3 on the list, all are seedlings from fruit bought in Chinese markets. So, there is no assurance that it would be any good (like any seedling), even if I manage to get them to fruit.
This fall, I may bring in a couple pots of tomatoes and beans as well. I started 3 pole beans in a pot in August, figuring that by the frost they will be getting pretty mature. I also have a tomato which I started from seed, yet it never really sized up. It’s getting there now, in time for the frost, so rather than planting it, I’ve been moving it to a bigger pot.
