help with rex begonias
Comments (1)You don't have an email address on your member page so this will have to do. Rexes (at least most rexes) will lose their leaves in winter. Pick off dead and diseased leaves to keep mildew at a minimum. Do not water heavily during these times ESPECIALLY if the room is cool. You have to give them enough water to keep the rhizomes plump but not too wet else the rhizomes will rot. Not an easy task. Humidity chambers (aquarium comes to mind) may help in this endeavor. I lost several last year despite being very careful on watering but the ones I lost were in a much cooler room than the ones I did not lose. I actually believe you can put them in a darker cool room (like a garage) and not water them for a month or longer and still be okay (I have done this before but it's hard to gauge when to water). Almost all of mine this year are doing fine because I have them all under lights and the room is a lot warmer than last year. Butch...See MoreAnnual Begonia or Perennial Begonia?
Comments (23)That is weird Kyle. Rhizomatous (which rexes are of this type) are fairly easy. Are you overwatering them? Several of mine took a turn south due to the week I was at the convention in New Orleans. Most are still viable and some are putting out new leaves. These are the smallest pots and on top shelves. I've noticed over the years that plants I put on top shelves (begonias) often do worse than the ones on middle and lower shelves. I can only think that it must be warmer (heat rises) and causes issues. The other thing is not seeing as well since I could just be watering blind unless I take the tray down (I do that in one room - 9 trays in all that is a bit more work than I like). These photos are from March 12 as I have only taken a few photos of cuttings after that. I even got Escargot through winter this year! YAY! My 3 red rexes have never looked this good until I cut back on watering this winter. This big pot was started in September from 3 inch pots. 3 rexes, 1 U647, and Bashful Bandit in the middle. Sophie plants that I started over the previous winter and gave away several. Mary Bucholtz in the back, manicata in front plus several others.

Comments (19)Thanks so much for your postings, everyone! I would like to try propagating from leaves that I saved from the stem cuttings...for insurance. Yesterday, a friend gave me a stem broken from a begonia I have admired since I first saw it in bloom a few years ago. He said I could probably get about 3 stem cuttings from it, which we did. We cut all the leaves off, leaving a small triangle of leaf on each petiole. We dipped the stem cuttings in rooting hormone, tapped off the excess, and stuck them in a pot of dampened perlite. We placed the pot in indirect light with a ziploc bag over the top. The pot had too little perlite for my liking (approximately 1", but it was very late at night...too late to get some from the shed...so my husband said it will have to do ("the roots will grow laterally", he says.) Today, we added some fresh perlite to the pot to bring the level up. I'm skeptical about the success of these stem cuttings. I'm not sure of the name of this plant...my friend only refers to it as "Ann's mother's plant". He propagated it from that plant many years ago. I haven't been able to figure out which subgroup it belongs to. Maybe it's cane-stemmed...but its leaves aren't assymetrical or deeply toothed to lobed, as cane-stemmed begonias usually are. Its leaves are green angel wings with white speckling, are smooth as silk but not shiny, and can be as large as 10" in length! My friend grows the plant tall and upright with supports, but the large clusters of deep red flowers are pendulous. So maybe it's a rex-cultorum and my friend just keeps it tall? His plants are probably 7 to 8 feet tall! If anyone can identify this plant, I would be interested to know what you think it might be. Thanks again for your help on leaf cuttings. Since I no longer have the stems attached to the leaves, I will try some leaf cuttings in water and some with scoring on underside of leaf at mid-vein/mid-rib pinned flat to vermiculite. (I kept the leaves in a platic bag.) Hoping for success!...See MoreI didn't think I liked the rex begonias but
Comments (4)There is no one place to find out about names and photos. I'd start with the ABS site (begonias.org) and go from there. There is an international database that has a lot of names and some photos. It has a link on the ABS site or just do a search for begonia international database. Plenty of other web sites as well but again - no one site comes close to covering everything. Another suggestion is to do an image search - rex begonia for example. The problem is there are a lot of misnamed plants on the web which is a pity but that is the nature of the beast. I have several hundred begonias and a lot of them have no names or the wrong names. Buy the plant for its beauty rather than the name. Then years later you may actually find a name for it. For example, our oldest begonia was a passalong plant to my wife and was simply named Angel Wing. Turns out this is a common name for a lot of cane type begonias. We've had this particular begonia for almost 41 years now and found the true name perhaps 15 years ago thanks to the web. Its real name is Corallina de Lucerna and most folks abbreviate it to Lucerna. Another plant I bought from a mail order place (Glasshouse Works) was supposed to be crassicaulis. It didn't look like crassicaulis from all the photos on the web but I liked the plant and it grows very easily. I gave it a nickname - Sprawler until I found the true name just a few short years ago - Bayberry Lane. So hang in there......See Morepetrushka (7b)
