Presence in Maine

Please note that the lupine is by no means extirpated in Maine — Preceding unsigned comment added by 98.11.132.140 (talk) 11:50, 11 June 2020 (UTC)[reply]

I added some better inline referencing to that section. Looks like USDA PLANTS, BONAP, NatureServe, and the Maine Natural Areas Program list it as extirpated in Maine. The latter says:

Aids to identification: Wild lupine [Lupinus perennis] is very similar to the common lupine (L. polyphyllus) that has naturalized itself in fields and on roadsides. Both have blue-purple to pale pink pea-like flowers and palmately compound leaves. Wild lupine has 7-11 leaflets, only reaching 5 cm in length, compared to the naturalized lupine which has 11-17 leaflets that reach 13 cm in length. [...] Conservation considerations: Unknown, has not been seen in Maine in several years. Possibly mistaken for the common, introduced lupine. Some populations may have succumbed to residential development.

Can you provide some alternative references for the presence of Lupinus perennis in Maine? I also checked GBIF and iNaturalist observations and all of them were misidentified (mostly Lupinus polyphyllus) and/or planted by people. Not that iNaturalist could be used as a reliable reference itself, but just to check another source of potential observations, since sometimes new things pop up there before making it into official sources :) —Hyperik ⌜talk⌟

Article on lupine and communication

while I'm sure that this article is authoritative, it is likely that most readers will not benefit from reading it. It is full of jargon that it simply uninterpretable toost readers. No doubt that the author(s) intended to succinctly tell readers what the plant looks like without misleading, perhaps the description would have benefitted from drawings, illustrations, or photographs. As written, the article belongs in a botany tome for experts--who can access the article in their university's library. Why write the article if it doesn't coummunicate to most readers? 76.18.180.220 (talk) 18:02, 21 May 2023 (UTC)[reply]

Hello, I will be adding two citations including germination and land management. I will be adding this:

The germination of this plant isn't too selective over day and night as both still occur equivalently. Researchers found that the seeds of L. perennis require scarification to germinate and ideal temperatures range from 24–29C (75–85F).

Wayne A. Mackay, Tim D. Davis, Daksha Sankhla, Don E. Riemenschneider; Factors Influencing Seed Germination of Lupinus perennis. Journal of Environmental Horticulture 1 December 1996; 14 (4): 167–169. doi: https://doi.org/10.24266/0738-2898-14.4.167

Impacts of primary habitat loss have led to decreasing populations which are small and scattered which makes it harder for pollination to occur. Changes in land management such as prescribed burning, mowing, and mechanical thinning, would help protect and promote this plant and other plant diversity. Further research is still needed for future interventions.
