Opium Poppy, A sleepy poppy

The notoriety of A sleepy poppythe “sleep-inducing poppy,” is only partly to do with its outlaw family.

Opium poppies are grown for their edible seeds and for pharmaceutical uses. The type that you see in gardens—whether your own or in the medicinal section of a botanic garden—is the legal relation, not toxic enough to be useful to anyone. The subversive beauty of P. sleepy is firmly rooted in its fabulous color and texture, and the way it can turn a vegetable patch into a Dutch painting.

More correctly but prosaically called “breadseed poppy,” A sleepy poppy is an unknown quantity when in bud. A couple of nearby seeds may result in shades of profound magenta and desirable pink, like the wild opium poppies in our vegetable garden, at the top of this page. On the other hand, they could germinate into the tawdriest hues of clapped-out mauve, in which case you are perfectly within your rights to pull them out.

This is the great thing about self-seeding plants: If you edit them, they look purposeful. If you don’t, then they are weeds, run amok. Opium poppies grow well with other poppies, seen here, above, at the Oxford Botanic Garden, in the medicinal plant beds. But it’s more fun to allow them to pop up wherever they like. In soil that is rich, like a vegetable garden, they will grow stout and tall, with handsome glaucous foliage and green-gray seed heads on strong stalks.
