A weird plant profile: Penstemon digitalis ‘Husker Red’

It seems strange to write a profile of a plant I would never encourage you to add to your  garden, but I think we all have those that we are grateful to have, even if they are not the best behaved

Penstemon digitalis  ‘Husker Red” is truly a self-seeding thug.You let those flower stalks stay one mili-second past the their bloom time and several million seeds will find their way to all corners of the garden and you will be weeding it forever plus one day. Once it has seeded and started to grow it requires more than a tiny pull to evacuate, and will often nestle right in at the base of other plants forcing you to work very hard indeed to extricate it,DSC_0006

BUT , ( there is always a but , huh?) It is 100% rabbit  proof. They never touch the stuff and I am pretty sure it has to do with the reddish leavesDSC_0004 (2).I have been diligently  reading  what little research is out there on anthocyanins,, a chemical  present in plants in part responsible for the reddish pigmentation. It comes into play in New England’s spectacular Fall color, and will also appear in green leaved plants when they are exceptionally dry. It is clearly prominent in Husker Red in the leaf coloring and there is work being done to see if there is an olfactory component ( in other words can it be detected by smell/taste ) that make it a deterrent for herbivores and insects. The research is so far scarce and the questions being raised show it is a very complex subject , but  I have noticed that plants that either emerge with red leaves or have them season long suffer far less predation than their green counterparts. That is anecdotal evidence  at best, but if it means that I can have asters if I plant “Lady in Black” instead of ” Alma Potschke’. I am a believer.

This penstemon , like all others, is also a pollinator magnet ,attracting all sorts of bees and that long tubular shaped flower along the dramatic red stalks tell you the hummingbirds will adore it ( and they do)DSC_0003.It brightens up the areas of the garden I let it seed in, and is one of the very few things that is planted in drifts here because I love the long delicate wands of white tinged with lavender  bringing color and life to the garden over a long period of time.  and the leaves remain through the winter  providing some interest when the ground is bare of snow and many of the other perennials are completely devoid of vegetation.DSC_0001 (2) DSC_0005

if left un-dead- headed , the seed heads are very cool  for texture later in the season, but they come with a price of more weeding out. They also smell like dirty feet , but in an arrangement that is placed out of the way , they look great.

On a rainy day like today it is a joy to look at at the garden and see  the Husker Red flowers bringing such a spark of life , via color and pollinator action. It is certainly not the only Penstemon I grow, or even close to my favorite, but it certainly has it’s place in the great scheme of things over here.DSC_0001

    I also have “husker red” in my garden. Nice contrast to the yellow berried holly in back of it and coordinating color to the heuchera in front of it. Perversely, I’d be happy to have it proliferate, but it’s very mannerly and is staying put.
