Moss Phlox (Phlox subulata) is a richly flowering, clump-forming phlox that stays green in both summer and winter. In spring these plants produce innumerable crimson and white flowers that attract butterflies. Phlox feel at home planted in full sun.
Just to see the interior scale of one of these small sheds. My purpose would be a place to cook the broth outside of the house, perhaps run a dehydrator, have some shelves for lacto-fermenting, and a sink to wash garden produce.
