Great Blue Lobelia [Blue Cardinal
Flower] Started from on November 16, 2011 shows
that Nodding Onion Garden's seeds are fertile.
Most interesting point . As you know
most sources, such as the Prairie Moon Nursery where you get some of your native
plant seeds say these seeds need to be stratified. That is, exposed to a cold
cycle like it would get in normal outdoor winter setting and should include
light .The book "Growing and
Propagating Wildflowers' by William Cullina gives a different appraisal .
Cullina says the Lobelia will behave like an aster without stratification but it
must have light to propagate. This photo that shows the plant about an inch high
supports his claim.
