Year-round
This plant contains toxic tropane alkaloids in every part, especially the seed pods, and it is genuinely dangerous to children and pets, not just an ordinary flower. It also spreads wide and can look sprawling, so think about placement before you plant it in a front yard.
- Every part of the plant, especially the seeds and flowers, contains tropane alkaloids (atropine, scopolamine, hyoscyamine); keep it away from areas where small children or pets play and never leave seed pods lying on the ground.
- Grows about 1 to 4 feet tall and 3 to 6 feet wide, so give it at least a 4 foot circle of space.
- Needs full sun and moderate water; once rooted it tolerates North Texas heat and short dry spells.
- Large white trumpet flowers open at dusk and fade by mid morning, blooming June through September.
- Wear gloves when pruning or removing spent flowers and pods, the sap can irritate skin.
Its sprawling, somewhat weedy habit and large spiny seed pods can read as unkempt to an HOA reviewer, so keep it out of the street-facing bed and deadhead regularly if front-yard visibility matters.
Fall
Bloom continues into fall until the first freeze, typically mid November in North Texas, and this is when spiny seed pods are most likely to be present in the bed.
- Expect blooming to continue through October and taper off at the first hard freeze.
- Walk the bed weekly and remove spiny seed pods before they split and drop seed, especially if kids or pets use the yard.
- Fall is not the planting window for this plant; spring is better. Save fall for woody trees and shrubs instead.
- Cut the plant back to the base once the first hard freeze blackens the foliage.
Blackened, frost killed foliage left standing reads as neglected; cut it back within a week or two of the first freeze.
Winter
Top growth dies back to the ground after a hard freeze, but the root usually survives a typical North Texas winter and resprouts in spring.
- Cut the dead stems back to 2 to 4 inches above the ground once frost has blackened them.
- A mild winter with only short freezes rarely kills the root; a severe Arctic outbreak can, so it can behave like an annual in a hard winter.
- Clear away and dispose of any leftover seed pods over winter rather than leaving them on the ground where pets or kids play.
- No fertilizing or watering needed while it is dormant.
A neatly cut back bed reads as intentional over winter; leaving dead, floppy stalks in a front bed does not.
Spring
Spring is when new growth appears from the root or from self sown seed, and it is also the planting window if you are adding one from a nursery pot.
- Plant nursery starts after the last frost (mid March in North Texas) once nights stay reliably above 45F.
- Watch for volunteer seedlings from last year's pods and pull any you do not want, wearing gloves since the whole plant is toxic.
- In heavy black clay, plant high on a slight mound or amend for drainage; in the sandier soils west of the metro it will need water more often through the first summer.
- Water new plantings twice a week until you see fresh growth, then taper off as the plant establishes.
A young plant stays low and unremarkable in spring, so there is little curb appeal concern yet.
Summer
This is bloom season: expect large white trumpet flowers that open in the evening and close by mid morning through the hottest months.
- Flowers open at dusk and fade by mid morning, with the heaviest bloom from June through August.
- Water deeply once or twice a week during 100F stretches; the plant is drought tolerant once established but blooms best with consistent moisture.
- Deadhead spent blooms before the spiny seed pods harden, this cuts down on both self seeding and the amount of toxic seed sitting in the bed.
- Hornworm caterpillars sometimes feed on the leaves; this does not change the fact that the plant itself is toxic to touch and eat.
The large white flowers read well from a distance, but spent blooms and seed pods left in place make the bed look ragged fast; deadhead weekly if it faces the street.
