5. Tillandsia Airplants
Tillandsia plants can grow and prosper
without soil. They belong to Bromelia
Family and grow on trees ,rocks,walls or
where they can grap hold. Their roots serve
only to give the plants a firm anchor to
whatever they are growing on .They are
provided with a particular mechanism for
deriving the moisture and nutrients they
need to survive. Tillandsia leaves have
specially developed cells called trichomes
that allow water and nutrients to be taken in
from rain, the air, and dust.
The trichomes work like trap doors; as the
plant dries out, the trichomes open to absorb
more moisture and nutrients. Once sufficient
hydration is achieved, the trichomes close to
retain the moisture. The dense concentration
of trichomes on the leaf's surface allows the
plant to absorb more moisture and to reflect
the harsh effects of the sun. These trichomes
are what give many of the air plants their
characteristic gray color. They are native to the
warmer climates of the Americas and leave
and grow in sunny areas

Natural Stabilized plants and flowers are
The result of a unique process of conservation of plants consisting in the substitution of the lymph with a product for a stabilizing treatment.
Plants and flowers do not need any maintenance:
No water
No soil
No need of light
and they last for approximately 10 years
