I don't know what they are either but they are so different and so elegant they make a lovely picture!!!

I love these flowers, too. I only have the pink, and the white of the angel trumpets (datura), but have had the double purple, too. If you get the chance, go by them in early morn, or evening, to get a smell of their wonderful aroma. White, to me, is the strongest and sweetest. Also, if you feel especially bold, perhaps ask the people where this plant lives, for a cutting- they root very easily. Just take off the bigger leaves, to help the cutting focus on roots.

Zone 9-10

Datura is a succulent shrub with brittle wood native to Brazil, but some say the mountains of Chile and Peru. There about 20 different species

The Datura grows fast, upright, often forming an umbrella-like canopy, under which huge 9-12 inch trumpet shaped flowers descend. The flower opening can easily be 5-6 inches and Datura is also very fragrant

A mature shrub may reach 15-18 feet if it's happy. Blooms are seen from late spring through fall. A healthy and happy brugmansia may sport 100-200 flowers simultaneously - an extremely dramatic display

Notice in the picture newly forming flowers, green and unopened. Also see three shades of open flower - light green, off-white and peach. That is the flower color development sequence in this variety

Plant in full sun to partial shade in most soils. Provide some wind protection so as not to spoil the flowers. This shrub is best planted as a free standing specimen to show off the blooms without crowding from other plants. Water to establish, then Datura is normally carefree. Protect from frost to be sure of success in zone 9

You may have heard this plant is poisonous and it is. On the other hand, natives in Brazil smoke the leaves for a strong narcotic affect said to relieve asthma

There are several colors of Datura. Datura sanguinea has bright orange-red flowers. Datura suaveolens shows off white flowers. Some datura blooms are one solid color, some two toned or even three shades of color

Datura candida is rarely seen and sports a complex triple flower - a trumpet in a trumpet in a trumpet

Datura metel is a double bloom, purple trumpet in purple trumpet, much smaller and not nearly as dramatic as Datura aborea. Sometimes seen with white flowers.

In south Texas I am able to grow these in clay soil very easly from seeds. The purple and white that i have are triples and grow up to 8 feet tall. In early fall after rain they bloom very intensely and each bloom will produce a seed pod. The pod is round shape with sharp points and green with some purple shade. The purple and white will bloom all year long as if it does not get under 40 degress.Harvest the pod after it is about one inch in diameter and let it dry out. Caution use rubber gloves.

The plant produces a white sap if cut. I have made contact with it and devolped a large rash on my skin. Yes the plant is poisonous.

If you grow the plant please be careful It is beautiful but deadly.

Yes, they are indeed beautiful!!! i love it too!!
