READY LATER IN THE SEASON. A very special Jacob's Ladder, this one. A compact plant, forming a neat mound of the usual ferny fingered foliage, from late spring onwards, short upright stems holding clusters of clear blue flowers which are unique within the genus in being fragrant. Very, very nice indeed. Semi-shade preferred. Any reasonable soil. 15 in. 2 litre pot.
