There are other variegated polemoniums out there, but this is undisputably the best of the lot. With creamy white edges to the leaflets, it looks terrific all season (with some pink hints in cool temperatures). But when the pale lavender blue flowers are added to the mix, seemingly hovering around the clump of foliage – wow! Sun or semi-shade. Any reasonable soil. 12 to 15 in. 2 litre pot.
