I've been doing this regularly, which entails essentially getting
inside the thing. It is rewarding me with rebloom! After a brief
hiatus after the first flush, it has pretty much stayed in bloom.

Cass, do you deadhead this rose? You had mentioned that it pretty much
had just one bloom at a time--and mine did last year in its first
year. But this year it is staying full, and very pretty.

For those of you who are not familiar with this rose, it is a single,
a china from the 1890s, with five petals and a pleasing, mounded bush
shape. It buds coral and each flower runs the color gamut from orange
to yellow to pale pink to hot pink. (I hope I got the order right!)
The catch about deadheading is that it makes many many many many
blooms. It is a zennish thing, hanging out with a good-sized mutabilis
long enough to find all the spent bloom nubbies and remove them.
