I saw this question on “Why is the foliage turning yellow on this climbing indoor vine?” and have a tangential question. Plants in question are pictured. All indoor plants.
So understand the concept of natural variegation in these leaves but I am puzzled. On the left-hand side of the picture the green leaves are fairly solidly green. On the right-hand side, there is clearly some variegation of yellow spots.
For a bit of background, I live in NYC. The deal is clippings of this specific plant have existed in my family since the 1970s. Basically my dad bought this in the early 1970s, and kept it alive up until the 1990s when he passed away. I took the plant and I would start making clippings to make more plants and more plants.
As far as I remember, for the past 15 years or so the leaves were solidly green. But in the past 2 years I moved into a new building and the water from the pipes is—frankly—not so great. I drink bottled and filtered water personally but use tap water to water these plants.
Many of these clippings were just sitting in jars of water until a few months back when I potted them. But after I potted them and placed them in a sunny window I was stunned not only by the mottling of yellow, but also the size of the leaves and stems on these mottled clippings is noticeably larger than what I ever remember them to have been in the past. Growth also seems quite aggressively faster than what I remember.
Which is all to say: What would cause this big difference between the plants on the left-hand side of the picture versus the right-hand side of the picture? Could it be something in the water from the tap? The fact they are now in a pot? Level of sunlight in a new location? Maybe something connected to the terra cotta pots? Some are pots made in Italy and others made in Germany if that matters.
In the great scheme of things, I’m not complaining about any of this. But as someone who essentially has grown up with clippings derived from this plant for decades, I am a bit baffled as to why this kind of sudden change has happened now.
