Asparagus officinalis flowers

Asparagus officinalis flowers

Flowering - May - June.

Habitat - Pastures, fencerows, old cultivated fields, disturbed sites, open woods, roadsides, railroads.

Origin - Native to Europe.

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.
