Sanguisorba tenuifolia var. purpurea ex compact forms (Purple Japanese Burnet) [12 Seeds]


Germination Information: I recommend these seeds only for gardeners who have experience with seeds that benefit from or require a chilling period. The easiest approach is to surface-sow the seeds in a pot in fall to late winter, setting them outdoors in a spot protected from mice so they can germinate when conditions are right in spring. (The winter-sowing method works very well with these seeds.)

If you sow after February, give the pot an artificial chilling period of about a month.

It is possible that these seeds could germinate (though perhaps at a less than optimal percentage) if you start them in warm, moist, bright conditions. But if you try that and no seedlings appear within 6 weeks or so, then try the artificial chilling period. However you sow, it is not unusual for germination to be slow and irregular.

Note that this information will not appear on the seed packet you receive.

I’ve had purple Japanese burnet (Sanguisorba tenuifolia var. purpurea or S. tenuifolia ‘Purpurea’) growing here at Hayefield for many years, producing its typical reddish purple flower heads atop 5- to 7-foot-tall stems in late summer into fall. Nearly a decade ago, I spotted a clump that repeatedly flowered at about 3 feet tall without any pruning. I collected seeds from it, and the offspring were also compact: in the 30- to 40-inch-tall range. There is some variability in the foliage and flower size but all had the usual bloom color. The compact clumps are growing well away from typical species plants here but I can’t guarantee these seeds will produce naturally compact plants; still, if you are a fan of Japanese burnet, or if you enjoy investigating uncommon variants, you may find them worth a try. Full sun to light shade; soil that’s on the moist side is best. Perennial; Zones 4 to 8.

Collected in mid to late October 2023. Each packet contains at least 12 seeds. Shipping to US addresses only.
