Many, many people love and adore this flower but find it hard to get the right variety. By the right variety I mean the one that grows tight over rocks and stones and gets into crevices in walls. Well, 'Mrs. Rosholt' is the name of this variety. 'Mrs. Resholt' is a low-growing, spreading, semi-evergreen to evergreen perennial with small kidney or heart-shaped, toothed, mid-green leaves and racemes of star-shaped, mid- to violet blue flowers in summer. It is not a difficult variety to grow but a few rules apply:
Rule No 1
While campanula loves dry conditions it need to be well watered till it gets established .
Rule no 2
You will needs patience ,while this plants grows fast it does take a while to get established.
Rule no 3
The best time to stick this plant into crevices of walls is October, but you will not get this plant for sale then as it is always sold out in early May.
Rule no 4
Buy plants now and grow them on in the ground or in larger pots and containers - this will give you a ready supply of material that you can stick into crevices and holes. These will get anchored in over winter and start to grow the following Spring, giving you your required effect you had wished for.
Rule no 5
Campanula is good combined with other rockery plants, especially aubretia, the purple spring flowering rock plant that most people confuse with campanula. A combined planting will give you a prolonged flowering season from Spring right through to late summer.
Campanula loves well drained soil, so add lots of grit if you are planting in the ground or in pots. If planting into stones walls, just use some wet soil mixed with Westland slow-release fertilizer. Campanula can be evergreen in dry conditions, but in damper soils will lose its foliage for winter.
