- Description and general information
- Vitaliana primuliflora is a member of the Primrose family and is closely allied to Androsace and Douglasia. The genus is named in honour of Donati Vitaliano (1717-1762), who was a professor of botany at Turin, Italy. The species is native to alpine regions of southern and west-central Europe.
- This species has a tufted habit, making it ideal for troughs, crevice gardens and the rockery in general. In spring (June in Newfoundland) plants produce nearly stemless 5-petalled yellow flowers.
- In the north, Vitaliana seems to thrive best in full sun but further south, shade from mid-day sun may be suggested. In the wild, they often grow on open, north-facing slopes. Soil should be on the alkaline side, well-drained yet not prone to drought.
- Bloom period
- In the Pyrenees I have seen this species blooming in early May; in Newfoundland, June is its bloom time. (In Calgary, it blooms through May.)
- Cuttings, seed and division
- These are the directions suggested on the Ontario Rock Garden Society website. Sow at 20C for 6 weeks, then place at 4C for 6 weeks, then slowly raise temperature to 10C for 6 weeks. If there is no germination, repeat the cycle.
- I've had mixed results with dividing; essentially they fall apart into seperate stems when divided. Bits with roots can be planted a little deeper and may root along the buried stem similar to taking cuttings. Unrooted bits can be used for stem tip cuttings.
- Probably the easiest way to propagate Vitaliana is by cuttings. Plants root quite easily from stem tips taken just after flowering. I have rooted them in a mix of peat/sand in a shaded frame.
