  We construct a new set of boundary conditions for higher spin gravity,
inspired by a recent "soft Heisenberg hair"-proposal for General Relativity on
three-dimensional Anti-de Sitter. The asymptotic symmetry algebra consists of a
set of affine $\hat u(1)$ current algebras. Its associated canonical charges
generate higher spin soft hair. We focus first on the spin-3 case and then
extend some of our main results to spin-$N$, many of which resemble the spin-2
results: the generators of the asymptotic $W_3$ algebra naturally emerge from
composite operators of the $\hat u(1)$ charges through a twisted Sugawara
construction; our boundary conditions ensure regularity of the Euclidean
solutions space independently of the values of the charges; solutions, which we
call "higher spin black flowers", are stationary but not necessarily
spherically symmetric. Finally, we derive the entropy of higher spin black
flowers, and find that for the branch that is continuously connected to the BTZ
black hole, it depends only on the affine purely gravitational zero modes.
Using our map to $W$-algebra currents we recover well-known expressions for
higher spin entropy. We also address higher spin black flowers in the metric
formalism and achieve full consistency with previous results.
