Plant Name |
Veronicastrum sibiricum "The etymological root of the binomial name Veronicastrum is named for Saint Veronica, who in Christian mythology gave Christ her veil to wipe his forehead while carrying the cross. Sibiricum is derived from the Latin meaning from Siberia." from Davis Landscape Architecture - "We are a London based landscape architectural practice, located at Elephant and Castle, within hearing distance (when the wind is in the right direction) of Big Ben in central London. Where applicable, we advocate the use of shared space in the public realm. This is where the boundary between carriageway and footway become unclear, creating uncertainty for the road user, encouraging them to slow down and pay more attention to pedestrians. This often creates a more inclusive space which is actually (counter intuitively) safer." |

Comment |
Erect Form. Pruning Group 14. "All in all, this is a great plant for the middle to the back of your perennial border. Height has been 36”-48” in my garden, and the several week long bloom period starts in early to mid Summer. Full sun to part shade is OK, and I am sure that the window of tolerance for light and soil conditions is extremely wide. The genus Veronicastrum was separated from the genus Veronica. You wanna get technical and understand why?? I put together this little chart to help you understand the workings of a Taxonomists mind." from Sunshine Farm and Gardens - "I envision Sunshine Farm & Gardens to be a bridge between the most knowledgeable people in a particular genus of plants and the home gardener. In the past 32 years we've managed to amass a diverse collection of well over 10,000 different, hardy to zone 5 perennials, bulbs, trees and shrubs from every corner of the Earth on our 60-acre mountain top at 3000 feet in beautiful Greenbrier County WV. The Display Gardens were completely redesigned by Mr. Matthew Bishop of Devon England in 1993 and several thousand new plants were planted in the existing 24-year-old garden. Take a virtual tour of the gardens through the photographs taken in June 2000 by world-famous garden photographer Mark Turner of Turner Photographics. Visitors are welcome with advance notice. While we are primarily a wholesale nursery serving the Garden Center, Landscaper, Landscape Architect, Landscape Designer and Wholesale Regrower market, we do offer limited mailorder to Home Gardeners where we have no established retailers." "This species has multiple 5- to 7-foot-tall, tapering spikes of pinkish-lavender flowers from summer to fall. They look like elegant, living candelabras and add a vertical accent to the back of a mixed border or wild garden." from Fine Gardening. "The landscape architect may find Veronicastrum sibiricum useful in an informal prairie type scheme or as part of a mixed herbaceous planting scheme. Ecologically, Veronicastrum sibiricum is attractive to pollinating insects. Veronicastrum sibiricum prefers moist, fertile, well-drained soils. It tolerates most pH of soil. Veronicastrum sibiricum requires little maintenance. Large clumps may be divided in spring or autumn." from Davis Landscape Architecture. Available from Fine Gardening in the UK with Digging Dog Nursery and Sunshine Farm and Gardens in America. Available as seed from Jelitto Seeds. |
