I received Lydia's Regal Robe in 2017 and by 2019 it was beginning to settle in nicely. First bloom this year was on 6/23/21 in my zone 6b garden and there are still five or six buds left to bloom.
In 2018 it had 4 nice large fans and today I counted at least 10 fans, so it multiplies at a good rate. Nine scapes bloomed this year - one with 3-way branching and the rest had 2-way branching. One scape had 9 buds and the rest were lower with the lowest at 4 buds. It does have some bud-building ability which is always nice.

This year, it really showed off those beautiful dark blooms.
It is registered at 37 inches and I do believe it gets about that tall. I like it when the blooms are well above the foliage and the scapes hold them up.
