Ctenanthe burle-marxii ‘Amagris’ (Fishbone Prayer Plant, Ctenanthe Amagris)
Though its variegated leaves aren’t that dramatic, the dark green fishbone pattern set against a light greyish-green background certainly attracted our attention and curiosity!
The purple-coloured underside of its leaves is an added bonus, to say the least.
They thrive well at this location which receives brief sunlight, depending on the planet’s motion around the sun. Air circulation here is rather cool and isn’t as dry as our garden at the front yard.
