How to grow questions for Datura and Brugmansia
Comments (5)The "standard" you refer to is because Brugmansia used to be called "Tree Datura" - they thought it/they were the same as Datura but with a different/larger growth form. They are not. Whether or not you pinch off side shoots or not is a matter of preference. If you are wanting the "standard" and aiming for a tree-form, pinch away. If you want the ability to have more more branches to cut and root for more plants, don't pinch them off - let them get bigger and woody, then cut/prune them off and root them - even while you can continue to let the top develop and - as karyn1 said, "Y" because that has to happen (unless your plant came from a post-Y cutting that was rooted) - and still, in the end, get your "standard". Or you might choose to allow it to grow in bush-form. I'd go with the best of both by allowing side shoots and growth, later pruning to root cuttings, and still all the while working towards the tree-form. HOWEVER, I have several in my meager collection that I have worked towards the tree-form while harvesting older side-growth to propagate, and time and again those particular specimens have "shown me" that they don't want to be tree-form, they want to be bush-form or "clumping" after a fashion - by sending up a new, stout shoot from the rootstock/beneath soil level. Then others are completely happy being "trained" with singular, vertical growth. There's a heck of a lot more difference between Datura and Brugmansia than growth habits. Did your Datura-from-seed bloom change from white to white with purple, a tint, or any striping, or has it remained white for the duration/until it was/is spent? Some go through gradient colour changes, others don't - and not knowing what species of Datura seeds you got and a whole bunch of environmental factors plus all the stuff "not registered" like sheer fluke. But if it continues to only bloom white and you paid for purple - I would raise so much 7743 with the eBay seller - BECAUSE Datura spp. self-pollinate and while they are OP, the fact of the matter remains that even for those of us who effort to manually cross-pollinate for controlled pollination & trial, the result is more frequently failure to successfully cross-pollinate and still ending up with a self-pollinate bloom and subsequent seed pod. In other words the seller can't hide behind a statistically unlikely cross-pollinated bunch of seeds as an excuse for why they are all white instead of purple - they either mixed up their own seeds on ID or they were misrepresenting the seeds. Sorry, unethical Brugmansia and Datura sellers really get under my skin and make all Brug & Dat fanciers look bad. Grah!...See Moredatura vs brugmansia
Comments (3)Thank You for this tidbit. Years ago I walked out of my apartment smelling a sweet perfumy bouquet and went searching. I walked down the hall of the third floor got in the elevator and went to the lobby. When the door opened I noticed a four foot high potted flowering shrub and I was enchanted by the giant trumpet flowers and stunning fragrance. Since then I've grown a variety of daturas and brought them indoors to overwinter. But as it turns out, all those beautiful down pointing flowers indicate my adoration is truly for brugmansias! It seems that even seed catalogs don't know the difference. Thanks again....See MoreBrugmansia - Datura Hybridization; Any Info?
Comments (15)Hybrids, Hmmmmmmm. I did some of that 30 years ago. We used Colchicine. I did a search on plant mutation chemical. My times have changed. Ever more toxic ways. Anyway I thought I would throw 3 cents in. Being a reborn plant newbie of less than 3 months my thoughts had drifted to our old reseach. I could make a new Brung and name it. I could name it after my wife and give it to her as a gift. To those of you who would like to toy with some hybrid work at home here is a little info. It is a pretty safe and easy method. Since chromosome segregation is driven by microtubules, colchicine is also used for inducing polyploidy in plant cells during cellular division by inhibiting chromosome segregation during meiosis; half the resulting gametes therefore contain no chromosomes, while the other half contain double the usual number of chromosomes (i.e., diploid instead of haploid as gametes usually are), and lead to embryos with double the usual number of chromosomes (i.e. tetraploid instead of diploid). While this would be fatal in animal cells, in plant cells it is not only usually well tolerated, but in fact frequently results in plants which are larger, hardier, faster growing, and in general more desirable than the normally diploid parents; for this reason, this type of genetic manipulation is frequent in breeding plants commercially. In addition, when such a tetraploid plant is crossed with a diploid plant, the triploid offspring will be sterile (which may be commercially useful in itself by requiring growers to buy seed from the supplier) but can often be induced to create a "seedless" fruit if pollinated (usually the triploid will also not produce pollen, therefore a diploid parent is needed to provide the pollen). This is the method used to create seedless watermelons, for instance. On the other hand, colchicine's ability to induce polyploidy can be exploited to render infertile hybrids fertile, as is done when breeding triticale from wheat and rye. Wheat is typically tetraploid and rye diploid, with the triploid hybrid infertile. Treatment with colchicine of triploid triticale gives fertile hexaploid triticale.

Comments (8)Well, there are several reasons. One, it is very poisonous. Two, based on one, it is calles Jimson Weed, a shorting of Jamestown Weed for a very good reason...being the original Jamestown settlement. Three, if you ever have bruised the leaves or stems of this plant its smell very very foul. However, the frangrance of the blooms is unparelled. Wildcat...See Moremdahms1979
