Biology and ecology
 An annual plant reproducing from seed but with
the ability to re-root after cultivation
 It is persistent in soils that remain moist most of
the time
 This plant has been introduced from Europe and
has become a troublesome weed especially in
gardens and cultivated fields
 Seeds can remain dormant in the soil for years
before germinating
 Purslane is edible and is widely used as a salad
green or cooked vegetable in many areas
Control
Prevention – Learn to identify plants; start
monitoring early in the season
Biological – No known biological control in our area
Cultural – Plant competitive grass or other cover crop
Mechanical – The plants are too close to the ground
to be mowed, hand pulling can help reduce the density
and seed population if done before flowering
Chemical – Purslane is susceptible to many herbicides:
refer to the PNW Weed Management handbook for
specific chemical recommendations

Where found – Scattered areas throughout Stevens County and is a big problem in gardens
and flower beds where herbicides are not generally used
