This is a sport of H. sieboldiana 'Elegans'
that has a chartreuse margin. Registered by
Walters Gardens
in 1993. It forms a large sized (27 inches high) plant with
moderately corrugated, wavy leaves with thick substance. Near
white flowers bloom in mid June into July.
According to
The Hostapedia by Mark Zilis
(2009), "I have yet to figure out why
'Northern Star' has been a failure in the garden. It should have
been a non-burning improvement on 'Frances Williams'...Skip this
one unless you have to have them all."
