Petasites frigidus, the Arctic sweet coltsfoot[2] or Arctic butterbur, is a species of flowering plant in the family Asteraceae. It is native to Arctic to cool temperate regions of the Northern Hemisphere in northern Europe, northern Asia and northern North America.[3][2]
It is a herbaceous perennial plant producing flowering stems in early spring, and large leaves through the summer. The upright flowering stems are 10–20 cm tall, and bear only 5-12 inflorescences, yellowish-white to pink in colour. The leaves are rounded, 15–20 cm broad, with a deeply cleft base and shallowly lobed margin, and rise directly from the underground rootstock. The underside of the leaves is covered with matted, woolly fuzz. It grows in moist shaded ground, preferring stream banks and seeping ground of cut-banks.[4][5][6]
P. f. var.
palmatus fruit and leaves
While there is some disagreement, some sources identify five varieties of P. frigidus:
-
Petasites frigidus var. frigidus
-
Petasites frigidus var. nivalis, sometimes referred to as P. nivalis or P. hyperboreus. This variety is common at subalpine and alpine elevations.[7]
-
Petasites frigidus var. palmatus, sometimes referred to as P. palmatus, palmate coltsfoot, or western coltsfoot; mâl-ē-mē’ (Konkow language);[8] or tä-tä-tē’;[9] pē’-wē is the root.[10]
-
Petasites frigidus var. sagittatus, arrowleaf sweet coltsfoot.
-
Petasites frigidus var. vitifolius[11][2]
Uses
The leaf stalks and flower stems (with flowers) are edible,[12] and can be used as a vegetable dish. A salt-substitute can also be made by drying and then burning the leaves. This black, powdery substance will provide a salty taste. However, given the high likelihood of the presence of toxic unsaturated, diester pyrrolizidine alkaloids in this species, consumption should be very limited.[13]

Petasites frigidus, coltsfoot dulce del ártico,[1] es una especie de planta del género Petasites nativa de regiones frías a templadas del Ártico en el Hemisferio Norte en el norte de Europa, norte de Asia y norte de América del Norte.[2][1]
Es una planta perenne herbácea que produce tallos con inflorescencias a comienzos de la primavera, y hojas grandes durante el verano. Los esbeltos tallos con flores miden 10 a 20 cm de alto, y poseen de 5 a 12 inflorescencias, de color entre amarillento-blancuzco a rosado. Las hojas son redondeadas, midiendo de 15 a 20 cm de diámetro, con una base hendida profunda y un margen superficialmente lobulado, la cual surge directamente desde el rizoma enterrado. La cara inferior de las hojas se encuentra recubierta de pelillos enmarañados y lanosos. Crece en suelos húmedos a la sombra, con preferencia en bordes de arroyos y laderas expuestas por las que filtra agua.[3][4][5]

Si bien existe cierto desacuerdo, algunas fuentes identifican cinco variedades de P. frigidus:
-
Petasites frigidus var. frigidus
-
Petasites frigidus var. nivalis, a veces designada P. nivalis o P. hyperboreus. Esta variedad es común en altitudes subalpinas y alpinas.[6]

-
Petasites frigidus var. sagittatus, arrowleaf sweet coltsfoot.
-
Petasites frigidus var. vitifolius[10][1]
Usos
Los tallos de las hojas y de las flores (con sus flores) son comestibles. Se elabora un sustituto de la sal mediante el secado y posterior quemado de las hojas; el polvo negro que se obtiene posee un sabor salado. Sin embargo, a causa de la elevada probabilidad de presencia de diésteres alcaloides pirrolizidínicos tóxicos no saturados en esta especie, su consumo debe ser muy restringido.[11]
