Plant very strong, with magnificent blue aerial clusters, very melliferous. Highly resistant to drought and difficult soil conditions (pebbles, rubble)
Prune the plants very shortly at the end of winter to favor vigorous and flowering young shoots.
Compact selection of Dutch origin (Herbert Oudshoorn), narrower than 'Blue Spire' and less spreading ; flowering a little paler than that of the latter. Ash gray foliage.
