Plants in genus glaucium
Glaucium grandiflorum
Glaucium grandiflorum is a perennial plant native to the Eastern Mediterranean, known for its scalloped blue-gray leaves and bright orange-red flowers. It blooms from late spring into summer and is self-seeding in well-drained, gravelly soils. This plant is used medicinally for its anti-inflammatory and analgesic properties and requires full sun to thrive.
Glaucium flavum
Glaucium flavum, also known as the yellow horned poppy, is a short-lived perennial with soft, toothed grey leaves forming an evergreen rosette. It produces 24-inch tall spikes of yellow poppy-like flowers in spring, and its silver-grey foliage remains attractive throughout winter. This plant prefers sunny spots with good drainage and is drought-tolerant. All parts are toxic, and it is considered a noxious weed in North America.
