The usual pink-flowered foxgloves cause my fingers to drum on the desk. Yes, the spikes of flowers have the English it-will-never-get-truly-hot early Summer lushness. (But yes, they often need a bit of staking.) And yes, I like how they very considerately die after flowering, getting out of the way for the hot-weather show of the heat-lovers that make the July, August, and September garden such a thrill. Just let one or two die in peace, to ripen seed, and you'll have pink foxgloves forever.
But, they are pink. And that limits them to the few places (I hope) where you don't also have a lot of fun yellow and chartreuse foliage. Why not a foxglove that loves to pal around with yellow? Then you could have foxgloves anywhere, no matter what other colors were happening. Here's the answer: Digitalis 'Flashing Spires'. Narrow all-green leaves and narrow spikes of pale-yellow flowers are both self-supporting. (Take that, pink foxgloves.) And the color goes as well with pink as it does with red or yellow or orange. (Take that, pink foxgloves.)
Yes indeedy, Flashing Spires self-seeds with gusto. But the plants are very easy to yank, or (if by some miracle you don't have Flashing Spires everywhere) transplant.
Like all foxgloves, deer avoid them completely. And Flashing Spires comes absolutely true from seed, so your spires will always be the same soft-yellow. (Take that, pink foxgloves, whose offspring vary from white to pink to rose.)
I've had Flashing Spires for year (and years), and in forty years or so, look forward to passing it on to my inheritors.
