Title: Argemone pleiacantha for Houston
Answered by: Nan Hampton and Joe Marcus
Since it is now growing in a more tropical area than its native range (New Mexico and Arizona), Argemone pleiacantha (southwestern pricklypoppy) will probably act more like a perennial in Houston. That doesn't guarantee that it will bloom all summer, however.
We would like to recommend that you consider substituting Argemone albiflora (bluestem pricklypoppy) or Argemone mexicana (Mexican pricklypoppy), two species that are native to the Houston area.
