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

$3.95

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 in a spot protected from mice so they can get a chilling period and then germinate when conditions are right in spring.

If you sow after February, set the pot in a plastic bag in your refrigerator for about 2 months before moving it to a warm, bright place for germination. (Remove the bag if the pot will be exposed to any direct sun.)

It is possible that these seeds could germinate when sown 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 a chilling period as described above.

Description

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 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. I assume these seeds will 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 2020. At least 30 extremely small seeds.
