Liatris spicata is not a bulb, its an herbaceous perennial with roots. If you have a packet with just roots in it, I'd be inclined to pot those up and keep them somewhere sheltered over winter - a cold frame would be good, but otherwise, a sheltered spot against a wall, out of cold winds, and plant out next spring.

Thankyou flag
What Ihave is three rather knobbly bulbs labeled liatris spicata they came with lots of perennials I purchased, they had no growing advice hence the question.
So thanks again

It does have a small knobbly tuber at the base though this is as said not technically a bulb.

I had 3 of these as well. I just stuck them in 3" pots and have put them in the greenhouse...was too busy to even Google them! Tch! tch! Thanks Bamboo!

Thanks again Bamboo,
The bulbs? are now in pots fingers crossed
