Other info. - The flowering
period is not really as important with this plant as the sprouting period.
This is when you can go out and collect the young shoots to eat. Why spend
$2 a pound when you can drive down the road and collect 5 or 6 pounds in
less than an hour? You just have to know where to go. White asparagus,
very trendy these days, are actually sprouts which have been grown under
a layer of mulch so that they do not produce chlorophyll. White and green
asparagus come from the same species or even the same plant.
The upper leaves of this species
are not really leaves at all but are, in fact, reduced branches. The true
leaves are scalelike and on the main stem. A officinalis
is a dioecious plant meaning that male (staminate) and female (pistillate)
flowers are produced on different plants.
