Isopogon formosus
Isopogon formosus (in their native Australia called " Rose Coneflower " ) is a plant of the family silver tree plants ( Proteaceae ).
Description
Isopogon formosus is a bushy upright to slender, evergreen, up to 2 m tall shrub. Young shoots are light brown to reddish- brown, silky, downy or short haired, later smooth or fluffy binding. The in tufts springing, stiff leaves are up to 6 cm long ( stalk to 2.5 cm, leaf blade to 3.5 cm). They are narrow - cylindrical, grooved, multi split, segmented and run into a stabbing tip. Young they are often hairy silky.
The pink to red-violet colored flowers appear from July to December and are cone-shaped, showy inflorescences of up to 6 cm in diameter at ends of branches or in the upper leaf axils. The bracts are ovate to lanceolate pointed, and hairy. The individual flowers can reach lengths up to 25 mm. When open, they tend to look down. The tepals are bald except for a tuft of hair on her head. The long pen is initially pale yellow and reddish colors later.
The fruits are ovoid, about 3 mm long, beaked and hairy nuts, containing a single seed.
Distribution and systematics
Isopogon formosus is in southwestern Australia in a predominantly coastal area endemic, extending south of Perth as of Brusselton and the Stirling Range on Albany to Esperance in the region, ie in a zone with a Mediterranean sclerophyllous vegetation. The species thrives in full sun to partial shade on well-drained, sandy to rocky soils over laterite or granite. The species tolerates light frost and temporary dry periods, however, no permanent moisture.
In Isopogon formosus two subspecies are distinguished, however, can not be consistently distinguish clearly between:
- Isopogon formosus subsp. formosus (leaves spreading, petals up to 25 mm long)
- Isopogon formosus subsp. dasylepis ( Meisn. ) Foreman ( smaller overall, leaves often close -fitting, flowers to 20 mm long
