Dracaena sport? Nutrient deficiency? Odd variegation

Tiffany, purpleinopp GardenWeb, Z8b Opp, AL(8B AL)August 3, 2012

This tree is growing a branch with some completely white leaves. I keep expecting the leaves to "turn normal" but as you can see, it's been doing this for a while, this branch started popping out about 6-7 months ago. The other branches continue to grow the same, normal leaves they started with. What do you think of this? Sport? Nutrient issue? Response to prior damage/stress? Common or making you mutter, "what the...?"

I can get the real camera out if seeing something more clearly would help determine. Just LMK.

Previous pics of this tree, if interested. Scroll down to Apr. 27 to start seeing pics that include this new branch.

That would be a chimera (kigh MEER a), a mutation. A sport is a mutation that occurs in a new shoot rather than expressing itself like this....over the whole (or half) plant.

Here is a link that might be useful: Click for your study hour....there will be a test

Purple, I love it! The white foliage.

I too have a Dracaena that was given to me by a neighbor..She hates plants inside her house.

The other Dracaenas in the same pot are light green w/darker green striping. The whiter trunk grows well, whiter..lol

Problem is it's hard to keep alive.

Thanks for the link! I almost get it. Will have to read a couple times. Can we know from just looking at this which type of chimera? Or is it necessary to propagate it to see if it continues to make new shoots like this?

Still confused from the rudimentary searching I did when I initiated this discussion since some of the info is conflicting regarding defining the terms. BUT this stem of this Drac has progressed to producing all white leaves... Really, maybe it's just getting "gray" from old age? Ha!

It's definitely a mutation in that stem, and it is pretty, but it could not be propagated separately from the parent plant as, producing no green leaves, it has no chlorophyll and is relying on that produced by the regular shoots to survive. Still, as long as the other shoots grow green leaves and photosynthesize, it should continue to grow,

I had a similar mutation in a potted vinca vine "Wojo's Jem" where one stem sprouted and grew in completely white. It grew very slowly but survived for a few months as the plant still had green leaves to rely on. Eventually, it died out though.

This same thing happens to a mint perennial I have in one of our garden areas. It grows a few stems and leaves that are white, while the main plant, itself, is mostly green with some variegation here and there. I have no insight, and must assume it's a genetic mutation in nature having to do with variegation... these things do happen.

In the end... we can manipulate Mother Nature to a certain extent, but we can't control her.
