Lobelia siphilitica ‘Alba’ (White Great Blue Lobelia) [30 Seeds]

(1 customer review)


Germination Information: I recommend these seeds for experienced seed-starters only, partly because they are very tiny and partly because they may require some patience. The easiest approach is to surface-sow 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 February, give the pot an artificial chilling period of about 2 months.

It is possible that these seeds could germinate (though perhaps at a less than optimal percentage) when started in pots in warm conditions, either indoors or outside. If you don’t see any signs of sprouting after about 3 weeks, then give the pots an artificial chilling period as described above.

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

The species great blue lobelia (Lobelia siphilitica) produces spikes of blue flowers in mid- to late summer or early fall on 2- to 3-foot-tall plants. This white-flowered form of this U.S native popped up in my Bucks County, PA, meadow a few years ago. When I sowed seeds I collected from that surprise plant, about 70 percent of them had white flowers; the rest were the regular (still beautiful) blue. These seeds should produce similar results. Full sun to partial shade, with soil that is on the moist side. Perennial; Zones 3 or 4 to 9.

Collected in September 2022. At least 30 seeds. PA ecotype.
