Poseidon is now well over five feet tall by approximately 5 feet wide now and grew taller than my fence and continues to get larger and more impressive!
All the other roses in my yard which include hybrids and antique own root roses suffer from black spot and powdery mildew issues and don't do well or grow vigorously, which include losers in my climate such as New Zealand, Chicago Peace, Drop Dead Red, Arizona, Sonia, etc..
It survives through the winter like a champ and constantly blooms beautiful flowers that keep blooming through late October when it gets cold out. The are the only roses in my garden that start growing new shoots/leaves in early April. These roses are the prettiest shade of lavender purple. Highly recommended for the NYC/Long Island area.

This is the first true bluish/lavender/mauve rose with enough blackspot resistance to grow well on the US east coast and escape defoliation without weekly fungicide spraying.
Its cultivar name is 'KORfriedhar'. "Poseidon" is its North American trade name, and "Novalis" is its trade name in Europe.
Bred by Kordes. In 2014, this cultivar won an ADR (the German low-maintenance, no-fungicide trial that inspired the Earth-Kind tests in the US).
Hardy to USDA Z5b. Habit is a bush and not a shrub.
Don't allow the North American trade name to lead you to confuse this rose with Tom Carruth's 2005 mauve hybrid tea rose 'WEKhilpurnil', whose trade name is "Neptune".
