About Bacopa 'Scopia Gulliver Purple'
Sutera cordata 'Scopia Gulliver Purple' · also called Scopia Gulliver Purple Bacopa, Large-flowered Purple Bacopa · flowering
'Scopia Gulliver Purple' is a trailing Sutera grown for unusually large purple-violet five-petalled flowers held above small green leaves from spring until frost.

Preferred mix: Moisture-retentive yet free-draining potting compost
Watch for — Root rot in stagnant compost: Waterlogging with poor drainage rots the root system. Use a free-draining mix and ensure pots drain even under frequent summer watering.
Why bacopa 'scopia gulliver purple' needs this mix
Bacopa 'Scopia Gulliver Purple' hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Bacopa 'Scopia Gulliver Purple' 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

- A free-draining, gritty mix dries too fast for bacopa 'scopia gulliver purple' — 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 bacopa 'scopia gulliver purple' dry out. It needs a moisture-retentive but still airy blend.
