info		 The blue, chalky, waxy leaves of this plant make it quite drought tolerant, though it will look its best when given water once dry. Shriveling or dropping of older lower leaves is a sign of underwatering (or possibly too little light.) Generally blue chalk sticks will want water every two to three weeks during the dry season to keep looking their best, with more frequent waterings in inland areas with dry heat.

Growing Notes

When grown as a groundcover, this plant will eventually begin to smother itself; once this happens it’s best to prune it back hard each spring, creating a cleaner form. These cuttings are easily rooted.
Blue chalk sticks will grow in the shade, but looks undesirable and as such this should be avoided. Also, avoid planting this plant where leaf litter accumulates as it is difficult to rake the leaves out without damaging the plant.
