I harvested leaves all summer, brought it in and it has grown like gangbusters in and outdoors ever since. It has even been knocked off ledges and put back in the pot. It still survives.
Just harvested a bunch for #1 daughter when she was here cooking tomato sauce for lasagna. It is the geneovese(?spelling?) variety. I potted it in Mels mix and give it a dose of dynagrow once in a while, and have to give it just a little water daily cause it is so big and the pot is so small.
It is vigorous, and is also evergreen. I ordered it online and it is excellent. I just wish that I had made a note of the company name, because I wouldn’t mind getting more of it. Next spring I’m going to try to either dig up part of one of the plants, or try to grow a cutting. It’s beautiful.
