Description
This perennial herb produces one or more stems up to 35 centimetres (14 in) tall from a woody root crown. It is hemiparasitic, obtaining water and nutrients from other plants by tapping their roots. This Castilleja species has been observed parasitizing eastern redcedar (Juniperus virginiana) and oldfield juniper (J. communis var. depressa). It reproduces sexually and vegetatively by resprouting from its root crown.[1]
The petals are fused and form a curvilinear tube.[2] The sepals are shorter, with narrow lobes.[2] Altogether, the inflorescence is green, yellowish, and pink.[2]
This plant grows in several habitat types, including prairie, shinnery, Texas savanna, and shrubsteppe.[1] It is pollinated by a hawk moth.[2]
