Gladiolus splendens weediness

I'm thinking that invasiveness is much like pornography.  You know it when you see it. But the criteria and the specifics vary with the place and time, AND the reputation of the supposed perpetrator, viz., is O. discolor the true perpetrator? Or has it been misidentified?

Dear Paul,

Gladiolus splendens is grown (propageted) by Annie's Annuals. You might ask them whether they've noted any tendency for the species to become invasive. I have had my plant for just over a year, and it has remained well-behaved.

On the other hand, I bought a Nothoscordum felipponei at the UCB garden in 2008. It turned out to be infected with Nothoscordum gracilis. As I couldn't separate the bulbs, I discarded the lot. I noticed later that N. gracilis had become an invasive nuisance in the UCB garden.

Our propagator has grown some Gladiolus splendens from wild-collected 
seed, but we are concerned about its weed potential due to its growth 
habit of sending stolons out from the main corm (and its ready 
germination).I wonder if any others in our coastal Bay Area California 
climate have observed any spreading of this plant. The issue of 
invasiveness always concerns us when planting out new material.
