Irrigation run time for irrigation uniformity tests was 45
minutes, with the tests were repeated four times for each
sprinkler type.
For CF testing, seven marketable-sized plants in 16-cm-
or cP diDPeter contDiners Zere SODced in Dn oIIset
pattern with one container diameter spacing between
rims of adjacent containers.
Twelve border plants were placed around the seven test
plants in the same spacing arrangement as the test plants.

for impact sprinklers and 35 minutes for Wobblers. CF was
measured for each of the seven test plants as described
in the first test Dnd three irrigDtion test DSSOicDtions Ior
each sprinkler type and container Size were carried out.
Plant height and width for all test plants was as described
in the Test One.
Results and Discussion
Test Two: 3lant species comparison
Plant species exhibited a wide range of water-capturing
abilities (See Table One).
CF values for marketable-sized plants ranged from 1.2
to 4.2 depending on container size and plant species.
%Dsed on resXOts it ZDs DscertDined thDt SODnts cODssified
as groundcover or globose exhibite the lowest CF values,
while semi broad spreading, broad spreading, and
spreading vine habits were seen to exhibit moderate CF
values. Upright spreading Habits were observed to enjoy
have moderate to high CFs.
In general, it was observed that large-leafed plant species
and species with greater height-to-width ratios tended to
have higher CFs than plant species with smaller leaves
and more spreading growth.
Test Two 3lant si]e and container spacing
CF was seen to increase as plant size of each plant species
increased (See Table Two), while container spacing was
