Flower colours are indicated using the colours given in The Heather Society's colour chart, with a code of the colour; thus, H9 is the code for the colour called beetroot.
Flowering periods are indicated by Roman numerals from I to XII (each equivalent to a month); thus, for example, IX-XII means September to December (in northern hemisphere).
Lilac-pink (H11) flowers, VII–IX, semi-double; mid-green foliage; broad compact habit; height 10–15cm; spread 31–45cm.
Seedling; found in their garden by Mr & Mrs W. D. Frearson (Coventry, Warwickshire, England) in 1970.
Named after the finders' daughter.
Heliotrope (H12) flowers, VII–IX, profuse, semi-double; mid-grey-green foliage; most hairs without glandular tips; erect habit; height 21–25cm; spread 31–45cm.
Wild-collected; a clone derived from the small population of E. mackaiana that grows near Carna, County Galway, Ireland, collected by Miss M. J. P. Scannell in 1970; introduced by Lawsons & Sons (Edinburgh, Scotland) in 1975.
Named by D. McClintock after Miss Maura Scannell, who collected it; former Head of The Herbarium, National Botanic Gardens, Glasnevin, Dublin.
Magenta (H14) flowers, VII–X, double and packed with extra "petals" to the point of bursting; dark green foliage; neat habit; height 10–15cm; spread 31–45cm. Suitable for ground-cover.
Wild-collected; found in Connemara, County Galway, Ireland, on more than one occasion during the last 130 years; the clone in cultivation was gathered in 1901 by Dr F. C. Crawford, but there is an earlier record (by A. G. More in 1869).
Named from plenus = full (i.e. double-flowered). The earliest names for this clone were 'Crawfordii', followed by 'Flore Pleno', but it may be argued that neither was validly published.
Lilac-pink (H11) flowers, VII–IX; dark green foliage; spreading habit; height 10–15cm; spread 31–45cm. This is fairly typical of the plants of Mackay's heath seen in Connemara, and it is named after the schoolmaster who first drew the attention of botanists to this species in the 1830s. However, there is no evidence it has any direct connection with him. Often listed as 'William M'Calla'.
