A cute little foxglove. I can't figure out its blooming habit. Mine bloomed this year in late November.

Subshrub from Spain and very close to Digitalis'relative Isoplexis. Flowers in its 2nd year with surprisingly dark orange flowers with deep red veins. Flowers last about one month and as with most Digitalis they produce a lot of seed.

This is what they like to call a short lived perennial and usually lasts for 3-5 years before dying. Needs a very well drained soil to over winter and isn't fully hardy (especially where wet winters prevail) so winter protection may be needed.

Cuttings and seeds are the best forms of propagation and will germinate in 4-5 weeks. The seeds are small and require light to germinate so they are best surface sown and kept at a temperature of 65-75 degrees F.

It can be a prima donna to grow.
