I planted it in a shady bed and it spread so happily (and beautifully) that I wondered if it was going to become invasive. However, in the succeeding years, it has not become pushy. I enjoy seeing its bright colors among the irises, mahonia, and |

In this environment, tuberous begonias die out, impatients scorch their leaves, but Chinese Foxgloves.... thrive amazingly! This plant propagates on its own by producing new plantlets from underground runners. These are very easy to remove and I transplant them into making straight lines. They look awesome! |
| Positive | On Jan 28, 2010, annlof from Camarillo, CA wrote: I started six plants from seed (easy germination) and planted them in unimproved clay in full shade in my garden (zone 10, Southern California.) The plants spread by underground runners, and I suspect they might be quite invasive in good soil; mine are spreading but not at an unmanageable rate. Each flower spike continues to put out blossoms for a very long time, and so while the plant is never "smothered in blooms" there is almost always some color there. This plant is very tough and a good groundcover for shade. Slugs don't seem to bother it. |

| Positive | On May 21, 2008, MomKat from Mobile, AL (Zone 8b) wrote: This plant likes a bit more shade on the Gulf Coast, but is fairly easy to grow given even moisture. It spreads readily, but is also easily kept in check. It blooms all summer and is a great replacement for the more common types of foxgloves which won't grow in our heat and humidity! |

| Positive | On Mar 20, 2005, Zuzu from Sebastopol, CA (Zone 9a) wrote: This plant grows all over Sonoma County, in sun or shade, blooming for months and months, coming back reliably year after year, and reseeding liberally. It is not something I would categorize as a water guzzler, even in full sun. |

It has grown into one of the gardens highlighs. Beautiful glossy foliage and those mauve-rose "foxglove" flowers. Has been in bloom since Spring into early Fall. Another surprise for our Pacific Northwest gardens. |
| Positive | On May 14, 2002, M_Bond from Belmont, CA (Zone 10a) wrote: In the San Francisco Bay Area, this plant looks good all year. In the winter it is a nice clump of evergreen leaves, and in spring sends up many spikes covered in speckled deep pink flowers. It is a great plant for shady spots; even for rather dry areas. It is very easy to propagate by division, and does not seem to have any invasive tendencies in this area. I also have had no pest problems with this plant. I also have a beautiful white variety that is very hard to find, but very much worth the effort to locate. |
| Neutral | On Aug 30, 2001, Terry from Murfreesboro, TN (Zone 7a) wrote: This plant is also commonly classified under the Scropulariaceae family with other foxgloves. It can be invasive if given moist fertile soil; keep on the dry side to keep it in check. |
