From 12 february until 26 february 2018 we made another tour in Oman, together with Peter and Truus Groot. Also during this trip we found Dionysia mira in flower at the same location as in march 2003. On this occasion we also visited the Oman Botanic Garden, which is still under construction and not open to the public yet.
We were guided by Mrs. Annette Patzelt, senior manager of the garden. The Oman Botanic Garden has the unique aim of collecting, propagating and displaying the complete indigenous flora of the Sultanate of Oman.
Tufted perennial to 40cm across, the stems becoming woody with age, covered in the remains of leaf-bases. Leaves in lax rosettes, oblong to oblanceolate, 2.5-8.3cm long, with a slightly scalloped and blunt-toothed margin, covered on both surfaces by hairs and glands and with white woolly farina beneath. Bracts leaf-like, but smaller. Flowers borne in a scapose inflorescence composed of 3-7 whorls of flowers, one above the other; corolla yellow, the tube 15-18mm long, the limb above the other; corolla yellow, the tube 15-18mm long, the limb 7-9mm diameter, with entire oval lobes. Oman, Jebel Akdar, Jebel Aswad and Jebel Sharm, on sloping limestone rocks or cliffs, 1500-1900m. The most primula-like species, relatively easy in cultivation; treat it in a similar way to Primula floribunda or P. forrestii, keeping plants relatively dry in autumn and winter. Can be increased by stem and leaf cuttings, by division or from seed. It is not often seen in cultivation other than in Botanical Gardens, probably due to it’s somewhat ungainly habit.
