Polemonium reptas jacobs ladder division

Question

I’ve native Jacob’s Ladder in my garden. I’ve read that it only lives two years and comes back from seed, is this true? Because it appears mine has been there 5 years. I can’t find any info about cultivating the native variety and I hesitate to use the info for whatever the common plant is, because I don’t want to kill it. Can I divide this as for the common plant?

Answer 1

If you have five, I would try dividing one and see how it goes. I didn't find anything about dividing the native online. This article has a lot about the perennial and says it produces every two years.
