Question: Which species is an evergreen, Fatsia or Petrocosmea?

Context paragraphs:
Boninofatsia: Boninofatsia is a genus of shrubs of family Araliaceae, with two species.  The genus is sometimes included in "Fatsia".

Fatsia: Fatsia is a small genus of three species of evergreen shrubs native to southern Japan and Taiwan.  They typically have stout, sparsely branched stems bearing spirally-arranged, large leathery, palmately lobed leaves 20–50 cm in width, on a petiole up to 50 cm long, and small creamy-white flowers in dense terminal compound umbels in late autumn or early winter, followed by small black fruit.

Petrocosmea forrestii: Petrocosmea forrestii is a species of flowering plant in the family Gesneriaceae native to China, and sometimes cultivated as a houseplant.  It grows among rocks in shady places.  Like other species in its genus, it does not develop a stem above ground, but spreads by rhizomes.  The entire rosette of leaves is less than 15 cm in diameter.

Tetrapanax: Tetrapanax papyrifer (rice-paper plant, or "通草—tong cao") is an evergreen shrub in the family Araliaceae, the sole species in the genus Tetrapanax.  The specific epithet is frequently misspelled as "papyriferum", "papyriferus", or "papyrifera".  It is endemic to Taiwan, but widely cultivated in East Asia and sometimes in other tropical regions as well.  The species was once included in the genus "Fatsia" as "Fatsia papyrifera".

Petrocosmea: Petrocosmea is a genus of the family Gesneriaceae, the African violet family.  Most of the species within this genus are endemic to high-altitude areas in Western China, although some are native to other parts of Asia.  It is a rosette forming genus that generally grows on wet mossy rocks or forests.

Petrocosmea kerrii: Petrocosmea kerrii is a species of flowering plant in the family Gesneriaceae, sometimes cultivated as a houseplant.  In the past, it has been erroneously placed in the genus "Damrongia".  It was first described by William Grant Craib in 1918.

Fatsia japonica: Fatsia japonica(syn.  "Aralia japonica" Thunb. , "A. sieboldii" Hort.  ex K.Koch), also glossy-leaf paper plant, fatsi, paperplant or Japanese aralia, is a species of flowering plant in the family Araliaceae, native to southern Japan, southern Korea, and Taiwan.

Oplopanax: Oplopanax is a small genus of flowering plants in the family Araliaceae, consisting of three species of deciduous shrubs, native to western North America and northeastern Asia.  "Oplopanax" is closely related to the Asian genus "Fatsia".

Petrocosmea rosettifolia: Petrocosmea rosettifolia is a species of flowering plant in the family Gesneriaceae.  A new species "Petrocosmea cryptica" J.M.H.Shaw was described in 2011, long known in cultivation but mistakenly identified as "P. rosettifolia".

Fatsia polycarpa: Fatsia polycarpa is a species of plant in the Araliaceae family.  It is endemic to Taiwan.  It is threatened by habitat loss.
