Paeonia clusii is a relatively low (25–50 cm) species of herbaceous peony with scented, white or pink flowers of up to 12 cm in diameter. In the wild, the species can only be found on the islands of Crete and Karpathos (subsp. clusii), and Rhodes (subsp. rhodia). It has pinkish-purple stem up to 30 cm long and glaucous dissected leaves. P. clusii blooms in mid-spring.[2]
Description
Paeonia clusii is a
Root, stems and leaves
The main roots are slightly tuberous, up to 2½ cm wide, with thinner carrot-shaped side roots. The stems are mostly tinged purple, with several (up to nine) scales at their base. Leaves are split into three sets of leaflets, themselves further divided into twenty three to forty eight, 2½–4½ cm wide, ovate to lanceolate (subspecies rhodia) or to ninety five lanceolate to linear, ½–3¼ cm wide, segments (in the typical subspecies). The leaf is mostly hairless, but sometimes the lower surface carries a few hairs.[1]

Differences between the subspecies
Subspecies rhodia is characterised by twenty three to forty eight, ovate to lanceolate leaf segments, each between 2½ and 4½ cm wide. Subspecies clusii has between twenty three and ninety five leaf segments in the lower leaves. The segments are lanceolate to linear, each usually no more than 2⅔ cm wide, but rare exceptions to 3¼ cm.[1]
Taxonomy
In 1824, Joseph Sabine describes Paeonia cretica based on a specimen from the University of Oxford Botanic Garden, which later turned out to be synonymous to Paeonia arietina (named in 1818), and this plant probably originated from mainland Turkey, not from Crete. Another specimen, now from Crete, was described as P. cretica in 1828 by Tausch, but at that moment the name was no longer available, and hence invalid. Stern proposed P. clusii to replace Tausch's name. Stearn, in 1941, distinguished the population on Rhodes as a separate species and named it P. rhodia. Tzanoudakis however, points out it only differs in the number and shape of the leaf segments, and thus regards it as a subspecies of P. clusii.[1][4]
Etymology
Paeonia clusii was named in honor of the
Ecology
The typical subspecies grows in maquis on limestone between 200–1900 m altitude. Subspecies rhodia occurs as undergrowth of pines at an elevation of 350–850 m.[1]
Cultivation
Rhodes' peony likes well-drained, loamy soil or compost. It's hardy in the UK, but because it starts growing in late winter the leaves may be damaged by frosts. As can be expected from a plant from the Mediterranean, they suffer from wet soil.[5]
