Lithodora diffusa 'Star'

Plant details

Lithodora, once called lithospermum, has gentian-like flowers during the middle of the summer when few true gentians are blooming. Lithodora is, in any case, easy to grow and flowers well. The evergreen mats of foliage spread slowly to make good ground cover on a rock garden or scree. Unlike many rock plants, Lithodora needs a humus-rich soil, rather than a gritty one, so make a special planting pocket for them. Place several rocks close to the plant so the soil underneath remains cool and moist in a hot summer, giving the roots a reliable comfort zone. Lithodora ‘Star’ produces flowers that have a white edge, making the radiating blue colour of the flowers appear star-like.

The soil type shown above is chalky/alkaline but my Lithodora plant label says "acid soils" which is confirmed by a web search. Is your information incorrect?

I'm trying the soil type as above reading:
"Unlike many rock plants, lithodora needs a humus-rich soil, rather than a gritty one, so make a special planting pocket for them. Place several rocks close to the plant so the soil underneath remains cool and moist in a hot summer, giving the roots a reliable comfort zone."
as I'm planting in a narrow border by pond edging, seems ideal for that place.
It would be useful to keep in touch.
