Josephine, I apologize - I should have caught this when the first images came into the queue. I'm wondering if this is actually Datura 'Double Purple' which also has a white center. If not, can you give me some citations for this cultivar name? I wasn't able to locate any sources (commercial, academic or otherwise) that cite it.

I understand there's should be a checklist of Brugmansia and Datura registered names that was to have been made available to the public in late July or August, but I haven't been able to obtain a copy of it. (If anyone has the finished checklist, and can send it to me so we can verify our PlantFiles entries, I'd be very grateful ;o)

Hello Terry, I really don't know what to say a bout this. I don't have a list of named Daturas, I just named it like the way it looked to me.
I found this little 8 inch plant a produce market, and it said Datura Purple, but when it started blooming the blooms were not really purple, but white with streaks of purple.

I looked in the files and saw nothing like it so I dicided that I had a mutation, which can very well happen. Also the form was very different from the others I had seen.

However, the flowers on this plant are a little different every time it blooms, and the picture you showed is of the last bloom.

I joked that I should have called it Surprise Datura, since every bloom is different.
If you don't think it belongs in a new category, then remove it and put it where you think it belongs, I honestly thought that I had something really different, and may be I do, I don't know, but everyone said they had not seen one like it.
I leave it up to you, I know that you will make tha right decition.
Sincerely, Josephine.

Hi, Josephine...I went ahead and moved it to the entry for Datura 'Double Purple' - it fits the description (even if the blooms are somewhat variable.) For all plants submitted to PlantFiles, we use the following criteria to check the name:

1) If it is a species (including subspecies, varietas and formas), we look for citations in the standard encyclopedias and reference books such as AHS or RHS, Hortus, Gray's, etc. We also look to see if the name is considered valid by Kew, RHS, USDA (ARS/GRIN), MOBOT, etc.

2) If it is a cultivar, we first check for an international registry through ISHS/ICRA. Each registry is responsible for maintaining a checklist of recognized cultivar names and preventing the same plant from bearing more than one name, (or the same name being used twice for different cultivars.)

3) In the absence of a registry, we look for trademark/patented names, or at least widespread common usage - i.e., the plant has been sold and/or traded under a name for a good deal of time, and has become a generally-accepted name then we can use it, too.

Anyone can "dub" a plant whatever they want to call it in their personal records, but we have to use these standards for PlantFiles to keep our records as accurate as possible, even if it makes us unpopular from time to time ;o)

Dear Terry, thank you for the explanation, I didn't know about all those procedures, now I do and will know better next time.
I will look for my plant under the Double Purple category.
Josephine.
