Polemonium Stairway to Heaven
There are other variegated polemoniums out there, but this is the best. 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 – wow! Sun or semi-shade. Moist but well drained soil. 12 to 15 in. 2 litre pot.
