I compiled this list last year. I thought you might like to see it.
The following was taken directly from the book by Ulrike and Hans-Georg Preissel, Brugmansia and Datura, Angel's Trumpets and Thorn Apples and credit should be given to them for this information.
Datura stramonium (funnel-shaped small flowers with five sharp peaks; flowers are white- to creamy-colored or violet)
Datura stramonium var stramonium
Datura stramonium var stramonium f. stramonium
Datura stramonium var stramonium f. labilis
Datura stramonium var inermis
Datura stramonium var tatula
Datura stramonium var tatula f. tatula (has violet coloring in the center of the flower corolla)
Datura stramonium var tatula f. bernhardii
Datura stramonium var godronii
Datura ferox (five-peak small 2- to 2 1/2-inch flower of yellowish white; the flower usually does not open completely)
Datura quercifolia (oak-like foliage leaves; unremarkable small violet flowers with five short peaks; the flowers do not open completely)
Datura inoxia (flowers measure four inches across, are funnel-shaped, and are pure white; greenish veins end in five longer peaks)
Datura wrightii (flowers measure five inches across and are five to nine inches long; the upper section is usually violet to pale violet and have five peaks)
Datura ceratocaula (10-peak flower with inner sides of white to violet-pink and outersides have a bluish coloring.)
Datura discolor (One of the largest of the datura flowers; ten-peak flower with white upper section and a dark ring-shaped color of pale to dark violet in the center)
Datura metel (flowers are white or yellow or violet to red; fruits have conical humps)
Datura metel var metel (flowers are simple, white and double)
Datura metel var muricata (white flowers)
Datura metel var chlorantha (yellow flowers)
Datura metel var rubra (single flowers)
Datura metel var rubra f. rubra (single violet flowers)
Datura metel var rubra f. sanguinea (single red flowers)
Datura metel var obscura (flowers are single, violet or red)
Datura metel var obscura f. obscura (single violet)
Datura metel var obscura f. atropurpurea (single red)
Datura metel var fastuosa (outer portion of flowers are violet or red; inner portion is white)
Datura metel var fastuosa f. fastuosa (outer portion of flowers is violet)
Datura metel var fastuosa f. malabarica (outer portion is red)
Datura leichhardtii (ten-peaked small inconspicuous yellowish white flower, which do not open completely)
Datura leichhardtii ssp. pruninosa
Datura leichhardtii ssp. leichhardtii
sec. = sectio, section
ssp. = sub-species
var = varietas, variety
f. = forma, form
Seeds are plentiful of the Datura metel var. chlorantha (double/triple yellow) and Datura metel var. fastuosa (double/triple purple) and Datura wrightii and Datura inoxia and Datura stramonium. However, the others are harder to find quite frankly because they are not commerically appealing because the flower size is small, etc. or because they are rare.
Rj, I grow Daturas in containers, and I just use regular potting soil, but Daturas will have a problem if the roots sit in wet soil. They like really good drainage and often do best if they are a little rootbound. They are heavy feeders and need fertilizer to bloom well, but I wouldn't use compost or composted manure in containers because they contain too many gases. If the compost or composted manure is mixed into the topsoil, then they should be fine for Daturas.
Sure, Shelly. Your white is either Datura wrightii or Datura inoxia, and you should know that it is very difficult to tell the two apart. I have difficulty telling the two apart myself sometimes. The main difference lies in the peaks, and there are some other subtle differences as well. Both are beautiful and both are fragrant. Here's a link which attempts to distinguish them: http://www.americanbrugmansia-daturasociety.org/datura_inoxia.htm Dr. Preissel's book also attempts to distinguish them.
Okay. The leaves on yours looks so much better than mine. Do you feed them miracle grow? Thanks alot for the tip. I didn't know that about the wet. I may have mine too damp. Mine are all in pots except the currant swirls. I think the heat here must play a roll as well. I have my swirls in the ground and they are about 6 fee tall. They stop blooming when the temp hits 90 on a daily basis. When it cools down in Oct, they will start blooming again. I have a couple of double cream ones that are root bound, but they're leaves are scrawny. They are also very tall, about 4 feet in a pot. I was wondering if they like more acidic fertilizer?
If you don't mind, I will take a picture of the tops of the double cream and see what you think.
Many thanks again.
Daturas will grow as big as the root system will allow. Confining the root system will confine growth so, if you want more compact daturas, grow them in a container that crowds the roots.
The leaves of the Datura stramonium var tatula are indeed large, and there are varients which have smaller leaves as well. The Datura stramonium in the picture above does happen to have large leaves.
Yes, I do feed my Daturas and all my heavy feeders Miracle Grow, and I also feed them with a Bloombooster/Bloombuilder formula, which has a high middle number (phosphorus) such as 10-52-10. Both Miracle Grow and Schultz makes a Bloombooster/Bloombuilder formulas, and some other companies do too.
I don't think they prefer acidic fertilizer, which has a high nitrogen number, but I could be wrong. Plants which prefer acidic are gardenias, azaleas, magnolias, etc.
Daturas do quite well in part sun. You could move your containers to a part sun area, which may be cooler, and that may help to continue blooming in the heat.
Did you get Dr. Preissel's book? You will love it!
I didn't realize there were so many datura varieties. I too would like to know where to get seed for these varieties. I have not seen most of the varieties listed available for sale anywhere. After being on this forum for only a month, I think I'm hooked.
Kathyvm, most of the desirable varieties -- Datura metel, Datura wrightii, Datura inoxia, and Datura stramonium -- are commerically circulated, and seeds are easy to come by. The ones that are not desirable -- due to flower size, fragrance, growth habit, etc. -- aren't sold commercially and are hard to find.
My wrightii or inoxia (whichever it is) bloomed a couple blooms. It smelled wonderful! The 1st thing I thought of was a spicey lemony smell. The bees (which I havent seen one for a very long time) LOVED them! I couldnt help but wonder what the honey would taste like if you were to give the bees a field of these.
I'm new to all this daturas stuff but the flowers look great and I think I'm going to give them a try. I've notice that the white ones look just like moonflowers. The seed pods look the same too. Are they related? Is there much difference between duturas and brugs? Does anyone know if its better to buy seeds from Ebay or go though a store on the internet? I'm interested in the double yellow and double purple. Thanks
What a great thread. I have learned so much, and would love to try
many of the Datura varieties. I have only Datura Metel a lavendar color,
single bloom, which after a month, has failed to germinate. Watch-
I'll go check after this posting, and find it's come up!
Would anyone like to share any of the black currant swirl, or one of
the double yellow variety seeds? Clorintha or possibly fastuosa?
I have some flowering shrub seed, other than datura, I could share.
Does anyone have seeds for the yellow (doesn't matter is it's single, double or triple) dats in exchange for postage reimbursement? I currently have a dat with huge purple-tinged leaves (very similar looking to the 3rd picture from the top) and tons of bloom buds which are in various stages of "about to open" but are testing my "patience"...OPEN ALREADY!!! LOL...
Thanks for any consideration!
Jan...who is, in actuality, an impatient gardener :)
An excellent source of Datura seeds is J. L. Hudson, Seedsman (www.JLHudsonSeeds.net) I have had excellent success with their Dats (also everything else they offer)!! For a few dimes more, you should order the Datura seeds treated with Gibberllic Acid (GA-3).. Those are the seeds that have a"G" at the end of their ID #. All of these are listed as $3.00 each packet - generous amount ot seeds! The postage for 1 - 20 packets is only $1.50 , 21-40 packets is only $2.00 (this is not per packet, but rather, the whole batch!) The processing time is really fast - about a week. Once you order from them, you will get their catalogue in December every year - no pictures, but very accurate descriptions. You will be very pleased!!!!
I am new to brugs and daturas. I just bought this one, but it had no name. Can any one help ID her please.
Right now it is about 3 foot tall, and it has it's 2nd bllom. It is duoble yellow, and maybe triple. I know the pictures are fuzzy, but I will try to get better ones later.
I have alot of Daturas. They were given to me by a friend years ago when she moved. She gave me some seeds. I had no idea what they were but they were pretty and smelled great. With the help of you folks from DG I now know what they are. I have some seeds but they are old and I do not know if they would do anything so I would not like to share them, but in the late fall early winter I hopefully will get more and I will be glad to share. Through the years mine podded like gangbusters. I have found through experience they don't transplant well, I was succesful with transplanting some but, they are fussy about it. Are they for yall?
I just transplanted 16 seedlings, and all but 2 have made it so far. One of them all of about 6 inches tall, has a tiny bud on it. So far they are all doing well. I am going to the east texas roundup, Oct 11, in Tyler, Texas and will trade them there.
