The flowers are the most striking feature, being sweetly fragrant white trumpets up to {{convert|20|cm|in|abbr=on}} long, sometimes tinted purple, especially at the margin. Five narrow points are spaced symmetrically around the rim. The plants often can be seen as a ground vine in habit, growing close to the ground and spreading in a very exposed environment with full direct sunlight (cleared roadside).  ''D. wrightii'', blooms from April through October.<ref name=Cronquist/>  In clear weather, flowers open in the morning and evening and close during the heat of the day (depending on water availability); in cloudy weather, they may open earlier and last longer.

The seeds are borne in a spiny, globular capsule 3 to 4&nbsp;cm in diameter, which opens when fully ripe.<ref name=Cronquist/>

In Europe ''D. wrightii'' has often been confused with ''[[Datura innoxia]]'' as both are hairy with hanging spined fruits. They can be differentiated by the hairs on the stems and stalks, which for ''D. wrightii'' are densely appressed (visually and in photos this makes the stems look near-uniformly dull) and for ''D. innoxia'' projecting (making the stems dull at the edges and brighter, greener or shiny along the centre where the hairs project toward the eye). The flowers of ''D. wrightii'' are larger (14-26 cm) and have 5 cusps, with stigmas above the anthers often exserted, vs. ''D. innoxia'' smaller (12-16 cm) with often 10 cusps and stigmas below the anthers. <ref>{{cite web |url=https://alienplantsbelgium.myspecies.info/sites/alienplantsbelgium.be/files/2660771.pdf |title=Datura wrightii (Solanaceae), a neglected xenophyte, new to Spain |author=Filip Verloove}}</ref> and [https://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=gn&name=Datura NSW Key]
