Pauline Banyai of Michigan registered this open-pollinated H. 'Blue Boy' seedling in 1987. It has heart
shaped, blue green leaves and forms a medium size (12 inches high
by 18 inches wide), dense mound. The pale lavender flowers are borne
July into August.
The Hostapedia by Mark Zilis (2009), this cultivar is "... very similar to 'Blue Cadet' in foliage & flower."
