Begonia ‘Fannie Moser’

I bought my Begonia ‘Fannie Moser’ from Wagler’s Greenhouse on July 1, 2017. It has very deep, dark green leaves with silvery-white spots.

Sorry to say, but there isn’t a whole lot online about Begonia cultivars except growing information and features from companies selling them. I wish there were more information about who bred them, what species or cultivars were used in their creation etc. Sometimes I get lucky and find that information but not so for the Begonia ‘Fannie Moser’. I do know that Wagler’s gets theirs from North Carolina Farms.

Begonia ‘Fannie Moser’ produces these AWESOME clusters of very light pink flowers.

Typical leaf of the Begonia ‘Fannie Moser’ on 8-29-17, #369-22.

The leaves are a very, very dark green with small silvery-white spots. The spots look like they were painted on.

The undersides of the leaves are marron and there are indentations where the spots are on the other side. Very interesting, huh?

Begonia ‘Fannie Moser’ was a very beautiful plant even as temperatures started cooling off at night. Some of the others had started losing their leaves.


Inside for the winter on 10-16-17, #384-5.

As temperatures started getting cooler, I moved all the potted plants inside for the winter. Most of the cactus and succulents will be moved upstairs while the Begonias and a few other plants will remain in the basement. The Alocasia are on the other side of the basement.

All the Begonias made it through the winter in the basement with flying colors. When temperatures warmed up enough, I moved the plants back outside where they usually are for the summer. I had been busy doing this and that and didn’t get photos of the Begonias earlier. I could have cut the Begonias back, but I decided to let them grow as they were. They do need to be re-potted, though.

I think it is a good idea to re-pot Begonias once a year, especially if you use a potting soil with a timed-release fertilizer, preferably in the spring. If you don’t want to re-pot with fresh potting soil, then adding a water-soluble fertilizer to their water off and on is a good idea. After you have had your Begonia for a year or so, remove it from the pot to check to see if it is root bound. If so, then transferring it to a larger pot may be a good idea.

We had a bad Japanese Beetle infestation, worse than in 2017, so I had to move the most of the potted plants to the front porch on July 4. They didn’t bother the potted plants in 2017, but they started to this year. As you can see in the above photo, they did nibble on ‘Fannie Moser’s leaves a little. I caught it just in time. The plant tables were under a Chinese Elm tree that the beetles were feeding on. Even though the beetle population would drastically reduce within a few days, they changed the amount of light in this area from light to part shade to nearly full sun. So, I would have needed to move most of the plants anyway.

 Begonia ‘Fannie Moser’ is easy to grow and undemanding. Just follow a few basic rules and you will enjoy this plant. I will continue adding more photos and information as time goes by.
