More info for the terms: fern, follicle, fruit, shrub

Desert sweet is a densely branched, aromatic shrub 3.3 to 6.6 feet (1-3
m) tall. The stems and herbage are glandular and stellate-pubescent
when young. Desert sweet leaves are 0.4 to 3.2 inches (1-8 cm) long and
are twice-pinnately compound. They resemble minute fern fronds. The
inflorescence is a panicle or raceme and the fruit is a follicle with
few seeds [7,8,12,13,20].

Desert sweet is distributed from Oregon, Idaho, and Wyoming, south
through eastern California, Nevada, Utah, and northern Arizona
[7,8,12,13,20].

No information on fire ecology or related topics (conditions for
regeneration, sprouting ability, or successional role) was found in the

Desert sweet is generally found in dry, rocky habitats [7,12,13] from
4,500 to 8,000 feet (1,360-2,400 m) elevation in Arizona [8], and from
about 3,000 to 11,000 feet (900-3,300 m) elevation in California [7,13].
In eastern Nevada desert sweet is found in mountain brush communities at
intermediate elevations on xeric, rocky sites, usually on soils of
limestone parent materials [18].

Desert sweet grows well on gravel, sandy loam, loam, and clay loam soils [2].

Desert sweet is browsed by sheep, goats, and deer, but is not abundant
enough to be considered an important browse species [6,8,12].

Desert sweet and purple Dorr's sage (Salvia dorrii ssp. carnosa)-desert
sweet habitat types at Lava Beds National Monument, California, occur on
rocky basalt lava flows where disturbance by man, fire, and grazing are
very low [3].

Desert sweet occurs in pinyon (Pinus spp.)-juniper (Juniperus spp.)
woodlands in Arizona with true pinyon (P. edulis), singleleaf pinyon (P.
monophylla), Utah juniper (J. osteosperma), and oneseed juniper (J.
monosperma). Other associated species include broom snakeweed
(Gutierrezia sarothrae), scrub oak (Quercus turbinella), cliffrose
(Cowania mexicana), dwarf rabbitbrush (Chrysothamnus depressus), rubber
rabbitbrush (C. nauseosus), antelope bitterbrush (Purshia tridentata),
Fremont barberry (Berberis fremontii), green ephedra (Ephedra viridis),
Saskatoon serviceberry (Amelanchier alnifolia), banana yucca (Yucca
baccata), cholla or prickly pear (Opuntia spp.), blue grama (Bouteloua
gracilis), Arizona fescue (Festuca arizonica), and prairie junegrass
(Koeleria cristata) [10,11,14].

At upper elevations of the singleleaf pinyon (P. ,omophylla)-Utah
juniper (J. osteosperma) zone in the White Mountains of California,
desert sweet is associated with Great Basin bristlecone pine (Pinus
longaeva), limber pine (P. flexilis), wax currant (Ribes cereum), green
ephedra, desert bitterbrush (Purshia glandulosa), oceanspray (Holodiscus
spp.), and low rabbitbrush (Chrysothamnus viscidiflorus) [16].

More info for the terms: fresh, stratification

Little information concerning reproduction in desert sweet is available
in the literature. No pregermination treatment is required for fresh
seeds, although stored seeds require 3 months of cold-moist
stratification prior to planting [21]. Desert sweet layers when twigs
contact the ground (Fryer 2015 personal observation).
