The plant patent states: "The male parent was the variety Peace and an unnamed seedling as the female parent - the latter coming from a strain similar to Morning Mist." Therefore, the seed parent is NOT Morning Mist, but a related seedling.
A correspondent writes: Although 'Sterling Silver' is stingy with bloom production, a weak grower, a host to a variety of diseases, and not very winter hardy (unusual for an offspring of 'Peace'), it is the true and original lavender rose, being nearly thornless, and having a sweet and citrusy fragrance, and a certain prowess in the vase. The parent or ancestor of nearly every single modern lavender variety today.
That comment inspired this response from a fan of 'Sterling Silver': I totally disagree with the statement posted under this rose relative to bloom production. My 'Sterling Silver's are my TOP producers. They outbloom every other rose I own including 'Princesse de Monaco' who is a bloom machine. It is true that this rose needs TLC in the first 2 - 3 years; however once it becomes established it is a fabulous rose. It is not for those who are not willing to give it this TLC though. I am in No. Va. Zone 7A.
CAMBEL writes: I, like another person who commented about 'Sterling Silver' on this page, live in Northern Virginia. I stuck a 'Sterling Silver' in the ground, didn't do much beyond watering it, and out of three origional stallks, two survived the first year and produced blooms pretty regularly, it is already sprouting strongly for the second year. Is there perhaps something in the Soil of the Northern Virginia area that is particularly good for this variety? I've heard from friends in other areas that 'Sterling Silver' wouldn't grow in their areas.
