Ipomopsis aggregata (Pursh) V.E.Grant

국표에 없다.

Ipomopsis aggregata is a species of biennial flowering plant in the phlox family, Polemoniaceae, commonly known as scarlet trumpet, scarlet gilia, or skyrocket because of its scarlet red flowers with lobes curving back as if blown back by rocketing through the air.

Description

Ipomopsis aggregata has characteristic red, trumpet-shaped flowers and basal leaves stemming from a single erect stem. Depending on elevation, height can range from 30 centimetres (12 inches) in Rocky Mountain alpine areas, to over 1.5 metres (5 feet) in areas of southern Texas. Trumpet flowers can range from white, red, orange-red, and pink. Pink flowers are especially common in high mesa areas of Colorado, such as the Flat Tops, Grand Mesa, or the Uncompahgre Plateau. Yellow flowers have been reported for plant but are extremely rare. Fernlike leaves are low to the ground, helping encourage warmth in colder areas, and have silver specks and a fine white pubescence. A well-known delicacy in nature, I. aggregata is well adapted to herbivory, as it can regrow multiple flowering stalks once lost. Although herbivory initially reduces seed and fruit count of the plant, intermediate herbivory and its stimulating factors could lead to the plant growing larger over time.

In its first year, the plant appears as a cluster of distinctive leaves, which collect energy into the taproot, from which it rapidly grows in its second year.

Chemistry

Patuletin glycosides can be found in I. aggregata as well as eupalitin and eupatolitin.
