Lobelia kalmii and other Seeds
Moist seeds speaking, Caulophyllum thalictroides inventory has been replenished. I know it seems there is a lot of time left until the temperatures will start to plunge, but there are other things to take into consideration, like some seeds starting to germinate (Asarum seeds emerge their radicles at some point in November) or being sold out (Medeola virginiana, Trillium flexipes).
Dry seeds speaking, the inventory has been replenished for:
Campanula rotundifolia (still flowering, on-going collection)
Drosera linearis
Pinguicula vulgaris and
Primula mistassinica
For those who like to plan their orders, next to follow next week from the native species side: Houstonia canadensis, Clinopodum arkansanum, Gillenia trifoliata and maybe Delphinium exaltatum. Stay tuned…
Lobelia kalmii, Kalm’s Lobelia
And a short plant portrait for a new offering – Lobelia kalmii, Kalm’s Lobelia
A bit similar in look to the previously offered Lobelia spicata, Lobelia kalmii is a small size, floriferous and delicate looking plant with blue/lavender flowers that can be found in moist places such as sandy, gravely meadows, fens, tamarack (larix) swamps. It is also common growing in rock crevices and among boulders on the rocky shores of Lake Huron.
Looks like a perfect species to incorporate in the moist side of a rockery, or any other slightly moist garden location (edge of a border, ponds, waterfalls….). It may be delicate looking, just like Campanula rotundifolia, but perfectly cold hardy.
It is easy to grow from seeds and flowering in the second year after sowing in my garden. I just kept the seedlings with too much shade and they got elongated, but otherwise it is an easy going species (beware acidic substrates though).
The species and common names honor Pehr (Peter) Kalm, a Swedish-Finnish botanist, explorer and naturalist, student of Carl Linnaeus, who undertook the exploration of Northern N. American regions around 1748. Linnaeus will cite Kalm for about 90 species, many of them new, also naming the genus Kalmia in his honor.
At the end of the season, it is difficult to differentiate L. kalmii from L. spicata when they are found growing in the same locations. I suspect that last year, at least part of the seeds offered as L. spicata were from L. kalmii, so those who purchased seeds please get in touch to learn how to differentiate them after flowering: Contact form.
