My plants don't know or care whether they are "in" or not. They are simply happy to grow, unless conditions are not right.
It's true that i aim for an aesthetically pleasing garden--blues and yellows together, silvers and pinks. At the same time, i realize the impermanence of my entire undertaking. Twenty years from now, very little of "my" garden will remain. My collections will scatter and be overgrown and replaced by something or someone else.
Every curated collection is impermanent.
And so are we.
