Question 11) Of these five plants, do you consider them invasive in your area? Does your business sell or plant them?
Question 11 asked respondents to identify five plants as
to whether they were invasive in their area and whether or not they sold
(or planted) them. The five plants used in each survey depended on the
region in which the respondent was located.
14 respondents stated that they both consider one or more
plants (in Q11) invasive in their area and
also sell or plant it (Table Q11a). These
plants were Lythrum salicaria
(Purple loosestrife) (sold as cultivars or hybrids), Lonicera
japonica (Japanese honeysuckle),
Ligustrum sinense
(Chinese privet), Hypericum perforatum
(St. John's Wart), Elaeagnus
umbellata (Autumn Olive) and E. angustifolia (Russian Olive),
and Cytisus scoparius (Scotch broom).

1 respondent (from
Wisconsin) offered examples of other problem plants in their area, writing
in buckthorn? Tatarian
honeysuckle? (yes to both)".
Two more respondents
explained the use of particular plants. One from Michigan said that E.
umbellata is sold by the US Soil Conservation service. One from
New York said that E umbellata,
L japonica, and C
orbiculatus are "overused as [they are] cheap".
For some respondents,
they may have recognized a plant example as growing locally, but not consider
it a problem. One respondent from Pennsylvania answered that, yes, C
orbiculatus is invasive, but then wrote in It grows here. It's
not a problem.
