are they wild flowers

I pulled a bunch out last night thinking they were just weeds as they overgrowing. I doubt if I got all of the roots - will they grow back and if so any idea how long it would take?


Doug says that Rudbeckia are North American native plants but they have been hybridized to form a large range of gardening plants.

You pulled them out. OK - if you got most of the roots but left some, it is entirely possible they will throw new shoots. But that depends on a ton of variables that I know nothing about.

Similarly - how long will it take? It depends on your garden, your soil, your watering etc etc. Again, it could force them into dormancy and they'll reappear (or not) next spring. There's no one-size-fits-all answer when you do something this drastic to a plant.

Sorry not to be able to give a definitive answer here but there are too many variables.
