Today I was passing some of the street containers just as the city gardeners were changing plantings, and I got some of the ones I was most interested in identified; in particular, the fibrous root begonia, cultivar "Vodka." It has purple-bronze leaves, with bright red flowers. It is an annual, but one page I found said, "Bring them indoors as a houseplant during winter."
If I put them out in warm weather and bring them in during winter, how long will they last?
How long will "Vodka" begonias last?
Theoretically a very long time. Wax begonias really are tender perennials but most are treated as annuals. They will more than likely have mildew, drop leaves like crazy, grow leggy, and probably croak anyway when moved from growing outdoors to indoors. If you can provide lots of light in a semi humid environment then they may do okay. You may want to trim back hard before bringing them indoors and you can root the cuttings too.
