Another flower in the 5 lobe famila is Datura stramonium (I think also called Angel Trumpet flower), see link below. It has poisonous, hallucinogenic, and medicinal properties. It has been used for asthma attacks, and as a substitute for opium. An interesting plant as an ornamental, but use for other things with great caution.
Same family; the datura flowers are large and showy plants (and in frost-free climates can be kept year around to shrub out), the blossoms smell terrific though they don’t last long, and if they fruit, do not eat them, even though they look like eggplants (another relative, see the keywords). The fruit is also known as the “zombie cucumber” and is the source of the drug described in “Serpent and the Rainbow”.
Duuuuude....what?😆
Some are beautiful, some not so much. Thanks.
