A new cultivar of Andromeda named ‘Blue Lagoon’, characterized by its grayish blue foliage, its freely branched habit, its pink flowers in spring, and its hardiness at least to U.S.D.A. Zone 5. See US Patent page at http://www.google.com/patents/USPP22004
Not absolutely certain I have a ‘Blue Lagoon’ or a ‘Blue Ice’ variety! This plant seems to be difficult to grow, see e.g. this discussion.
2016.- No flowers this spring. However, this remaining specimen looks in good health and even starts to sucker in late June. I keep it watered through the summer.
2015.- No progress during the winter. 1 specimen is OK, the other one poorly. Added peat and sand. One specimen is dead and removed in June. The other specimen is fine and it flowers.
Planted 2 specimens autumn 2014.
