Whilst we are all familiar with the common Foxglove there is a whole world of Digitalis out there that are not seen often enough (here in the UK at least). What follows are some of the better ones that I've grown;
Digitalis parviflora is a truly perennial species. The flowers are small and brown but it is a really eye catching plant..............




Digitalis lutea is another truly perennial species...............




Digitalis ferruginea is a biennial or at best a short lived perennial..............




For some reason this is the only photo that I can find of Digitalis lanata var. Lutea............


Likewise D.laevigata which appears to be fully perennial so far.................


Digitalis Illumination Pink is a hybrid between the tender Digitalis canariensis (formerly Isoplexis canariensis) and another hardier species (there appears to be a lot of speculation about which but I've not found a definitive answer so if anyone knows). Hardy in a sheltered spot it's performance does diminish over three or four years. A bit of a gem though............




Finally, Isoplexis isabelliana. Much too tender for the UK and like all the other Digitalis it was easy from seed............

Beautiful collection of Foxglove , they are one of my favorite flowers, although I think a bit harder to grow in my garden.
Do they self-sow for you?
I have read other comments from people in the UK that come just short of calling them weeds.
Keep believing ,hoping,and loving
all else is just existing.

@gardengus - they mostly self seed. The Illumination series are sterile though.

The common Foxglove (D.purpurea) are what I would term weeds although that definition is a matter of personal taste. Over the years though I have bought several packets of supposedly pure white D.purpurea which have always ended up with speckled throats. So a few years ago a volunteer seedling appeared in a patch that was not ready to be planted up so I let it grow on. Lo and behold the following year I had a pure white Foxglove.............

Nice to see some great pics of unusual Digitalis! Thumbs up

I have grown Digitalis lanata 'Cafe Creme' and it is a beautiful and floriferous cultivar, easy to grow from seed, but unfortunately also short-lived - at least where I live.

I have also tried D. parviflora (species) and D. par. 'Milk Chocolate', both are easy to grow from seed and they last longer than the lanatas for me.

The purpureas grow well and self-sow, but I just move any 'volunteers' if they are in the wrong place, so I never think of that as a problem.
You don't know if it will grow until you try!

No, I haven't tried that one - not yet at least! Big Grin

I have a bunch of D. Stewartii that I grew from seeds last year and they should bloom this year, if they have survived the winter. Crossing Fingers!
