Après un incendie, la première fleur ?

A pioneer species in secondary succession, particularly after fires; it is generally present for 3 to 6 years following fire. Characterized by rapid invasion and growth, most commonly on dry soils of disturbed sites, frequently after fire. Hence, common near campsites, especially dry sunny exposures near the shore

General Interest: Pale Corydalis is a member of the poppy family. It is a plant that grows in areas immediately after a forest fire.

Pink corydalis frequently invades recently burned areas [28]. Seeds
stored in the soil often germinate following fire [1,4,21,24,25]. Pink
corydalis biomass generally peaks the second growing season after fire
[23,25].

The species is generally not found in areas that have not been recently
burned, although seed may be present in the soil [2,13]. Pink corydalis
has been reported to increase in lightly, moderately, and heavily burned
areas [6,25]. In one case, it grew better after a summer fire (on a
warm, dry forest floor) than after a spring fire (on a cool, wet floor)
[17]. In another case, seedlings of pink corydalis and of Carolina
geranium (Geranium carolinianum) emerged soon after a severe fire in the
Appalachian Mountains of New Jersey and were well established 1 year
later [29].
