Begonia boliviensis ‘Santa Cruz’ is significantly bigger than it was when I wrote about it three months ago. If I had known that it would have performed so well, I would have groomed it for better form. It grew upright at first. I just let it do so because I wanted to make a cutting from the tip when it got pruned back. However, because it leaned over and branched as it should, it did not get pruned back. It could have developed a better and lower form if I had tended to it better, but I am too pleased with it now to complain that it is a bit more upright than it should be. I do not mind that I did not get a cutting from the primary stem that I did not cut back because there are now many more stems that I can get cuttings from, simply be grooming out a small bit of superfluous growth from within. I could get many more than I want if I were to actually prune this specimen back for winter. It is getting to be too exemplary to cut back for winter, though. Nor do I want to leave it out to get frosted, as I might do with other begonias. The horticulturist who procured it will shelter it from frost, and perhaps groom it a bit after winter, but otherwise try to retain as much of this growth as possible for a head start next spring. I am curious to see what it does. Will it shed most of this growth as it resumes growth from below next spring; or will it grow from near the tips of where it stopped growing this year? I did not expect to be so impressed by this modern cultivar of Begonia.
