Do Iron Cross Flower Spread?

Iron Cross Flowers produce bulbs that help them store energy and return next year after the end of the frost. 

You can see the bulbs growing and multiplying naturally over time with the formation of small clumps. However, the spread is not vigorous.

Moreover, you can also multiply the plant from the rhizome division without facing the aggressive spread of the flowering plant.

Iron Cross Flowers also has the occasional self-seeding ability. The seed pods can burst in the suitable condition and spread the seeds near the parent plant.

Thus, if this perennial is spreading vigorously and taking over other native plants in your garden, you can simply deadhead the spent flowers to prevent the production of seed pods.

Overall, the Iron Cross flower is not an invasive species. This slow-spreading plant can fill the empty patches in your garden and make it look amazing.

However, make sure your pets do not roam around the Iron Cross plant as it is severely toxic to humans, cats, and dogs.

Moderate consumption may cause mouth irritation and swallowing problems while excessive amounts can lead to kidney failure and death.
