they do grow and fill in so amazingly! So another type of rupestre is the Blue spruce, which is a bluegreen, and it too spreads and grows so well! I have mine in semi shade, its full sun in winter, since around here they stay growing through the year - hooray! You can retry to take cuttings, and place them whereever you want, they should work with no big trouble!
There are a couple other rupestre's too, like Gold ball, and sea gold, which are slightly different but only up close would anyone be able to tell that it isn't angelina!
