Tumbleweed
While
Baby's Breath is used commercially by florists for flower
arrangements and bouquets, in the wild it is sometimes
considered a noxious weed.
A perennial
plant, it grows mostly in waste places,
fields,
roadsides, beaches and other open, sandy, disturbed sites. It
forms sizeable local populations in soils that are not strongly
acidic.The
plant can reduce the crude protein content of hay in fields it
infests.Livestock
will graze on the weed. In
Europe, the root is used for its saponin content.
The
white (or
rarely light purplish pink) flowers
appear in the summer and fall, then the plant dries back to its
skeletal form where it becomes tumbleweed-like.
At
maturity, the plant has a thick, deep penetrating root system
which allows it to survive in arid conditions. It survives by a
persistent root system which may extend four meters into the
soil. The overwintering roots, with abundant food reserves, give
rise to new shoots in the spring.
The
first shoots appear in late April. Branching develops on the
shoots in early May. The plants appear leafy at this stage.
Flower buds, which do not appear until the third year of growth,
appear in early June and occur in clusters. Buds appear from
early July into August. Fruits begin to form in mid-July and
mature and split open by late July.
Seedlings
emerge in early May. The seedlings grow to an average height of
six cm after six weeks of growth. Only one shoot (with no
branching) develops per plant during the first year. The shoots
remain green until killed by frost in the fall. Root growth
during the first two years of growth is rapid.
The
weed is able to invade and compete with other species in a
number of habitats. The greatest density of plants usually
occurs on protected slopes and in ravines where the supply of
moisture and opportunity to trap mature tumbling seed-bearing
plants is greatest.
Botanists
do not know how Baby's Breath pollinates but the floral
structure suggests cross-pollination. A single plant averages
13,700 seeds with wind appearing to be the most prevalent
disperser. Most seeds drop to the ground near the parent plant,
but if the seed capsules do not open completely, the seeds may
be carried lengthy distances before being dropped.
Botanical
varieties of Baby's Breath have been developed for compact
habit, abundant large petals, and/or pink petals. Occasional
naturalized plants are purple-tinged.
