In
botany a rosette is a circular or spiral arrangement
of overlapping leavesgrowing at a
shoottip or on a shortened
stem often at or close to the
ground level. The
leaves in a rosette are close
together and arranged in a compact circular pattern or cluster
that resemble the petals of a
rose.
Many
leaf succulents as Crassula, Haworthia and Sedum,
exhibit rosette-type growth.
Rosette succulents capture the
water that
condense
from nocturnal dew on the leaves of the rosette allowing the
plant to survive for long
period of drought.
This habit is habitual in
biennials
in their first year.
In
plants that form rosettes, the
basal leaves are those that
arise directly from the
crown of the plant, and which often
differ from
leaves arising from the
stem or on the floral
scape.
