Polemonium pauciflorum description
Beautiful yellow trumpet flowers with apricot markings in late spring and early summer.
I totally agree with the comment on the Rob’s Plants website  where he says:
I don’t know what it is with this plant, but its seed seems to be happiest as an imposter….We were surprised one spring (two seasons after we had first grown them) to find several self-seeded plants, blooming. I find it’s actually more charming when mixed at random into other plantings …
A pollinator friendly plant including bees.
This is a butterfly friendly plant.
How easy is it to grow:
Good for the middle of a border, or near a patio, but it is a little tricky and behaves like an annual if not happy. Once one or two self sown seedlings (which are not a nuisance) have found a comfortable place then they will continue on.
Common name: Yellow Jacob’s Ladder.
