Calceolaria uniflora Darwins slipper flower seeds Calceolaria uniflora, known as Darwins slipper flower is discovered by Charles Darwin in his voyage around South America. These unique flowers almost look like little orange penguins marching over the rocks. The Darwin slipper flower is winter hardy and likes cool climate. The best germination temperature is between 10 - 23 C and the germination takes around 3-5 weeks. ?Please soak them in water and put in a plastic pot. Sow the seeds on the peat pellets and cover the seeds with a thin layer of peat (about 2 mm). Then put the plastic pot in a zip-lock bag - with a pot size of 6 cm , a zip-lock bag of size 12 x 17 cm is recommended . Fill in the zip-lock bag as much tap water with a few drops of universal fertilizer, so that after the absorption of the substrate a few mm of water remain on the bottom. Location: on the windowsill or in a small greenhouse in partial shade, daytime temperatures at about 75-83 F, somewhat lower at night at 68-75 F. The resulting micro-climate provides ideal conditions for germination. price is for 10 seeds
