Silver Star
Common name for a small epiphyte
in the family Bromeliaceae,
with the botanical designation
Tillandsia
stricta, and in Thai referred to as
ton
tillandsia
(ต้นทิลแอนด์เซีย), as well as by its generic
name,
sapparot
sih (สับปะรดสี), i.e.
‘coloured pinnaple’.
The common English name derives from both its shape and the
natural film of
glaucous
coating,
i.e. the fine, silvery powder-like
substance that covers the surface of
its leaves and which in Thai is called
nuan (fig.),
yet in the Silver Star it actually consists of
microscopically small umbrella-shaped hairs, that are used to collect water and nutrients from the air, and give it the silvery colour.
This thick-leafed evergreen originates from the subtropical and tropical regions
of the Americas, yet is widely found in Southeast Asia as an ornamental plant.
As it absorbs water and nutrients through its leaves, which it collects from the air, it grows without soil
while attached to other plants. Yet, it is not parasitic, using its roots as anchors and depending on the host only for support. Hence it
could also survive on rocks or rock cliffs. As an ornamental plant, it is usually mounted on logs
or bark of dead trees, or on
dried
pong pong seeds.
As a perennial flowering plant, it will
bloom from March to May, producing small tubular, dark violet to purplish
flowers, that grow from lilac
bracts. The Silver Star is related to
Spanish Moss
(fig.),
an angiosperm with the botanical name
Tillandsia usneoides.
