Description

provided by Fire Effects Information System Plants
More info for the terms: caudex, forb

Cusick's giant hyssop is a dwarf perennial forb, usually 4 to 8 inches
(10-20 cm) tall with a spiked inflorescence. Numerous simple or
branched stems arise from a woody taproot and branching caudex. Leaves
are mostly 0.4 to 1.0 inch (1-2.5 cm) long and are finely puberulent.
The fruits are nutlets [3,4,5].

Distribution

provided by Fire Effects Information System Plants
Cusick's giant hyssop is found in the Steens Mountains of southeast
Oregon; the Santa Rosa, White Pine, and Toiyabe mountains of north and
central Nevada; and the Tendoy Mountains in southwest Montana. It is
also found in numerous locations in central Idaho [3,4,5]. In addition,
populations are reported from other mountain ranges in Nevada [10].

More info for the terms: caudex, fire regime

Cusick's giant hyssop often inhabits talus slopes that are not generally
susceptible to fire. It may sprout from the caudex following disturbance.

Immediate Effect of Fire

provided by Fire Effects Information System Plants
Specific information on the effect of fire on Cusick's giant hyssop is
not available in the literature. However, aboveground parts of
nettleleaf giant hyssop (Agastache urticfolia) were completely consumed
by late summer and fall fires in the Great Basin Rate of Spread Study,
which was conducted in Nevada [13].

Key Plant Community Associations

provided by Fire Effects Information System Plants
Mid- to high elevation sites in the Santa Rosa and Toiyabe ranges in
Nevada are occupied by scattered limber pine (Pinus flexilis) and
pinyon-juniper woodlands at the lower elevational limits of Cusick's
giant hyssop. On Steens Mountain, Oregon, Cusick's giant hyssop may be
associated with western juniper (Juniperus occidentalis), curlleaf
mountain-mahogany (Cercocarpus ledifolius), quaking aspen (Populus
tremuloides), or high-elevation sagebrush-grasslands [1]. In the Tendoy
Mountains, Montana, Cusick's giant hyssop is common on limestone talus
with mountain big sagebrush (Artemisia tridentata) and Indian ricegrass
(Achnatherum hymenoides) [7].

Agastache cusickii

provided by wikipedia EN

Agastache cusickii is a species of flowering plant in the mint family known by the common name Cusick's giant hyssop. It is native to the northwestern United States from eastern Oregon and central Nevada to Idaho and Montana.[1]

This perennial herb grows 10 to 20 centimeters tall from a woody taproot and caudex.[2] Some of the stems spread horizontally underground. It has leaves covered in fine hairs and the fruits are nutlets. The spikelike inflorescence bears flowers with purple-tipped sepals and white corollas each about a centimeter long with protruding stamens.[1] Blooming occurs in June through August.[2]

This plant grows in sagebrush and alpine ecosystems. It grows in dry, rocky mountain habitat such as talus slopes. In Nevada it grows in limber pine and pinyon-juniper woodland habitat. On Steens Mountain in Oregon it has been observed among western juniper (Juniperus occidentalis), curlleaf mountain-mahogany (Cercocarpus ledifolius), and quaking aspen (Populus tremuloides). In the Tendoy Mountains of Montana it is associated with big sagebrush (Artemisia tridentata) and Indian ricegrass (Oryzopsis hymenoides) on limestone talus.[2]
