Bonjour Paul, Also a bit late: Gladiolus splendens indeed spreads well by stolones, but is in no way an invasive thread. The mother bulb seems not to survive very long. I regluarly find it reppearingin our nursery . Again yesterday when showing around a group of visitors we had a lovely surprise to see its beaitful coral red flowers in a most unexpected place.

The issue of invasiveness always concerns us when planting out new material. Paul Licht, Director Univ.
