Weedy bulbous plants

One of the reasons I used the term legacy plants, when working on
what species might naturalize in gardens, was to avoid the use of the
word invasive.
As several members have pointed out, not all species are aggressive
in all gardens. Behavior can vary within 50 to 100 miles. So, as also
pointed out, knowing where a member gardens, and the climate, and
specific growing conditions that trigger ebullient growth, to pick a
different phrase, will help all of us make decisions for our own
gardens.
