Where a dense cushion effect of deep blue is desired in early Spring, procure a packet of Aubrietia seeds and sow in the open where they are to flower, covering the seeds very lightly; September is the best time to sow. As soon as the seedlings are well up, thin them to three inches apart and encourage them by watering, never allowing the soil to become very dry. They may also be sown in September in a cold frame, and transplanted in November or December to where they are to bloom. Where there is a stock of old plants they may be propagated by cuttings any time after flowering. There are several varieties, all of them very useful for carpet effects in early Spring.
