To plant or not to plant?

To plant or not to plant?

Earlier this year I bought a couple of hellebores and all was well until one of them started to go limp. I gave them a water as I'd been leaving them to the rain but it didn't help. I moved the compost so I could see what was going on and lower down the stem had gone brown and had something white and fuzzy on it. I removed the stem and the compost which had the white fuzz assuming that that would be the end of it but unfortunately not. The stems kept dying off so I repotted them with brand new compost after removing as much of the existing as I could on the presumption that it was contaminated (they came from the same place). They still kept dying so I wrote them off and just left them. I noticed the other day that on one of the plants a couple of stems were still alive and new shoots were coming up. Even more to my surprise, the one that had to all intents and purposes completely died also had new shoots. This makes me a very happy bunny and I would love to put them in the flower bed for which they were intended but I don't want to contaminate the rest of my plants. Does it sound as if they are safe enough now to mix with other plants without endangering them?
