Opening the flowering season all over the park and many other locations in Patagonia, it is one of the first flowers to bloom in this area.
It is an endemic species to the southernmost continental Patagonia. This genus comprises no more than 15 different species living in the andean mountain range.
Like most legumes, it is quite resistant to the hard climate conditions of Patagonia. This is in part explained by its adaptations like short stems to avoid the full impact of the dehydrating and cooling, almost permanent Patagonian winds and to keep it closer to the relatively warmer ground.
