This is large size sport of H. 'Krossa Regal' that was registered by Ron Snyder of Minnesota in 1994. It has a mixture of greenish white and mottled color in the center of the blue-green leaf. Lavender flowers bloom on extremely tall scapes in August.

According to The Hostapedia by Mark Zilis (2009), "Though 'Regal Providence' was registered as a sport of 'Krossa Regal', it should be thought of as a sport of 'Regal Promenade'...Both "Regal" cultivars are Ron Snyder's best and most valuable introductions."
