A field experiment investigating the phytoremediation potential of six plant species—Goosegrass (
Eleusine indica
), Bermuda grass (
Cynodon dactylon
), Sessile joyweed (
Alternanthera sessilis
), Benghal dayflower (Commelina benghalensis), Lovanga (
Cleome ciliata
), and Chinese violet (
Asystasia gangetica
)—on soil contaminated with fuel oil (82.5 ml/kg of soil) have been conducted from March to August 2016. The experiments consider three modalities—Tn: unpolluted planted soils, To: unplanted polluted soils, and Tp: polluted planted soil—randomized arranged. Only three (
E
.
indica
,
C
.
dactylon
, and
A
.
sessilis
) of the six species survived while the others died 1 month after the beginning of experimentations. The relative growth indexes showed a strong similarity between the growth parameters of
E
.
indica
and
C
.
dactylon
, each on polluted and control soils, unlike
A
.
sessilis
. Total petroleum hydrocarbons (TPHs) removal efficiency were 82.56, 80.69, and 77% on soil planted with
E
.
indica
,
C
.
dactylon
, and
A
.
sessilis
, respectively; and 57.25% on non-planted soil. According to the bioconcentration and translocation factors,
E
.
indica
and
A
.
sessilis
are involved on rhizodegradation and phytoextraction of hydrocarbons whereas
C
.
dactylon
is only involved into rhizodegradation. Overall,
E
.
indica
and
C
.
dactylon
out-yielded
A
.
sessilis
in the phytoremediation capacity of fuel oil-contaminated soils.
