I am trying to find a rockery type plant that I believe is named La-Cappanal, its foliage is similar to Abrietia & the flower is like a bluebell but its white. This plant will grow through walls & even make its way through cement. My mate has it in his garden & says its called La-Cappanal, yet I cannot find any info on it, I can only assume we've got the wrong name. Any help/advise will be greatly appreciated.
Cerastium tomentosum, (snow in summer) is quite able to push through small crevices and in walls and concrete?
