“Kenilworth Ivy” is one of my all-time favorites and I’m happy to have been able to establish it (I hope) here in its native region behind some gabions where it gets enough shade in summer.
I love its French name “Ruine de Rome” and I love its dainty snapdragon-like blue flowers blooming from April to October, depending on the climate. It grows out of cracks between stones and in walls and quickly spreads into shady corners. It is very frost hardy to -20 ℃ and drought-resistant (code secheresse 4/6) but needs a shady or half-shady location in well drained soil.
Cymbalaria muralis is a short-lived perennial but reseeds itself in an usual way: its flower stalk seeks the light until it is fertilized, then it turns itself away from the light to drop its seeds in shady crevices where they are more likely to germinate.
