Can anyone explain to me how these stripes formed?
Sorry for this very basic question...
It could be related to sunlight...but in this case the stripes are very regular ??? , could you please post a pic af the plant?
thanks
It grows in a greenhouse in Northern Italy and was the only one of that Astro collection to be that striped.
I found it rather peculiar but then I am no expert!
it is possible in hybryds of onzuka/whyte myrio with nudum myrio... but this one is nice anyway!=)
It is very nice and interesting too! Maybe the making of a new cultivar?
Could it be the stripes were caused by variations in growth during different seasons as a response to heat or strong light? Maybe each white and green line represents a year's growth..
@ C&D: It's difficult to believe that it depends on light, this is the only plant among many others that grow normal.
@ fanecchissimo: Have you see any similar ones around?
@ Simon: I thought also that it could be the annual growth, but then why the change? I don't think that it is a new cultivar but will enquire sometime 8)
seen some, yes. not as marked as this, but seen some. but i never buyed them,because i like most working with pure lines, and those looks really like hybrids. it depends on sun too a lot, as C&D told you. it could be that the plant is not in complete rest during winter and it develops some stripes, in fact i always leave in the same place white plants, because if you move them, thay can change a lot! =) hope it helps.

yes, it does! but i wonder whether the plant would not be a bit etiolated, if it grew also in winter...

I don't think that this is a matter of light, because plant looks very compact, and if it would not have a light it would grow like "totem" (or. looked like f.columnare). I just have to say : "Big up !"
i agree with you ToKra :)
actually i do not know exactly the reason of this growth, but light influences a lot the distribution of trichomes on the plant.
You can notice it putting some onzuka in full sun or keeping them in the shade...

...distribution of trichomes on the plant...
do you mean distribution i.e. less spots, or are they smaller or even absent?
in some nudal forms you can obtain stripes putting them to full sun for some months. but they are usually hybrids.
the same is the process C&D just told you... they can vary in density, dimension and "wool"...
@eve: why should a plant growing in winter be etiolated? the metabolism of the plant would be slower and the plant would grow a little without direct summer sunlight.
i have 50% shading in summer, but my plants are not etiolated.. this is because plants (even CAM ones) have a better metabolism in certain light exposures.
anyway this is not a bad form, just nothing never seen... ;D
