About Campanula lactiflora 'Loddon Anna'
Campanula lactiflora 'Loddon Anna' · also called Loddon Anna milky bellflower · flowering
'Loddon Anna' is a tall milky bellflower bearing airy panicles of soft lilac-pink, star-faced bells through midsummer to early autumn. A clump-forming hardy herbaceous perennial reaching around 1.2-1.5 m, it suits the middle or back of a sunny or lightly shaded border and reliably draws bees and other pollinators in cottage-garden plantings.
Preferred mix: Fertile, humus-rich, moisture-retentive but well-drained loam
Watch for — Flopping in rich soil or wind: Tall stems can lean or splay; provide pea-stick or ring supports in spring and site out of strong wind.
Why campanula lactiflora 'loddon anna' needs this mix
Campanula lactiflora 'Loddon Anna' hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Campanula lactiflora 'Loddon Anna' comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons campanula lactiflora 'loddon anna' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for campanula lactiflora 'loddon anna' — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets campanula lactiflora 'loddon anna' dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for campanula lactiflora 'loddon anna'?

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good peat-free houseplant compost works for campanula lactiflora 'loddon anna' straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
