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.
