Veronicastrum virginicum (Culver’s Root) [40 Seeds]
Germination Information: I recommend these seeds for experienced seed-starters only, because they are extremely tiny and need careful handling, and because they benefit from or require a chilling period.
The easiest approach is to surface-sow (do not cover) the seeds in fall to late winter, setting them outdoors so they can get a natural chilling period and then germinate when conditions are right in spring.
If you sow after January, give the pot an artificial chilling period of 2 to 3 months.
It is possible that these seeds could germinate (though perhaps at a less than optimal percentage) if you start them in moist, bright conditions, ideally around 55°F to 60°F. But if you try that and no seedlings appear within a month or so, then try the artificial chilling period.
Note that this information will not appear on the seed packet you receive.

Culver’s root (Veronicastrum virginicum) produces slender, spiky clusters of white flowers in mid- or late summer, followed by long-lasting seedheads atop stems that can reach anywhere from 5 to 7 feet tall. (Cutting the stems back by about half their height in late spring to early summer can encourage somewhat shorter, bushier growth, if desired.) The flowers of this US native attract many bees, syrphid flies, butterflies, and other pollinators and look right at home paired with other tall native plants, such as switch grasses (Panicum), Joe-Pye weeds (Eutrochium), and giant coneflower (Rudbeckia maxima). Full sun to light shade. Perennial; Zones 3 to 8.
Collected in early September 2023. At least 40 seeds. Unknown ecotype. Shipping to US addresses only.
