Description (by 't Hart & Bleij in IHSP, 2003) :


Glabrous herbs with a strong and woody rhizome and numerous spreading-ascending stems.


Leaves alternate, broadly ovate to narrowly oblanceolate or linear-lanceolate, spatulate or rhombic, obtuse, usually dentate, glabrous, shortly petiolate, 3.4 – 5 (-7) cm long, dark green; flowering branches 7 – 25 (-40) cm.


Inflorescences terminal, flattish, with (1-) 3 (-5) cincinni, bracts small, lanceolate, entire.


Flowers 5- to 6-meros, (sub-)sessile, sepals linear to lanceolate or ovate, obtuse, to 4.5 mm, petals connate for up to 2 mm, oblong to lanceolate, apiculate or rather long-mucronate, carinate, 7 – 9 mm, yellow, filaments nearly as long as the petals, yellow, anthers orange.


Cytology : 2n = 32, 48, 48 – 64, 64, 80, 96, 112, 128.


Note :

Ph. kamtschaticus is a very variable species and common in cultivation. The probably most widespread forms are Ph. kamtschaticus var. floriferus and its cultivar ‘Weihenstephaner Gold’ - both fairly rapid growers.
As plants are not especially succulent they enjoy a rather wet climate and suffer from drought.
