The plant shown was labeled
as 'Rising Tide' but is is actually 'Rising
Surf'. We will try to get a picture of the true cultivar.
'Rising Tide' was registered by
Walters Gardens, Inc. of Michigan, in 1984 as a sport of a seedling of H. 'Helen Doriot'. It
forms a large size mound similar to H. 'Sieboldiana'
with blue-green foliage with a chartreuse to
white marginal variegation and thick substance.
The Hostapedia by Mark Zilis (2009), "...some plants sold under this
name have been white-edged, 'Fortunei' type (10-12 vein pairs).
That form has been renamed 'Rising Surf'...The true 'Rising
Tide' has the look of H. 'Sieboldiana'-type (14-16 vein
pairs), similar to 'Northern Halo' and other white-edged Sieboldianas'."
