Because hairs on their speckled daybeds baffle the little bees,
Foxgloves hang their shingles out for rich bumbling hummers,
Who crawl into their tunnels-of-delight with drunken ease
Plunging over heckles caked with sex-appealing stuff,
To sip from every hooker an intoxicating liquor
That stops it propagating in a corner with itself.
And this is how the foxglove keeps its sex life in order.
Two anthers – adolescent, in a hurry to dehisce –
Let fly too soon, so pollen lies in drifts about the floor.
Along swims bumbler bee and makes an undercoat of this,
Reverses, exits, lets it fall by accident next door.
So ripeness climbs the bells of Digitalis flower by flower,
Undistracted by a mind, or a design, or by desire.
Ada Lovelace (1815-1852)
