Inflorescence 12 cm high, slender, very pubescent, covered with hairs up to 2 mm long, with two simple branches, with about 15 flowers, with very short pedicels.

Flowers 9- merous, 2.3 cm in diameter, red, buds ovoid-acute, calyx 6 mm long, sepals acute, ovate-deltoid, 4 x 1.5 mm, 0.6 mm thick, petals 10 x 2.9 mm, broadly lanceolate, apiculate, narrowed at the base, red, with a very narrow whitish margin, pubescent dorsally, strongly ciliate, filaments red, thinly glandular pubescent below, anthers red-spotted.

 

Some authors consider S. giuseppii a hybrid of S. arachnoideum x S. cantabricum, however the latter is not growing where the former is occurring.
