Very nice, how would you describe the light you give this plant?

Right now it gets about 2-3 hours of direct sun, and bright, indirect sun the rest of the day. I have grown them in much sunnier conditions, and they're healthy enough but don't get as big. When they come in for the winter they're under very bright LED lighting

 

[adnedarn]

Do you see it shrink under the bright led as in the sunnier conditions?

'Nice plant! I really love this species The form I have shows reddish/pink streaks in winter during cooler weather. I don't know if that is the norm or not. Right now they're just big and green.

No I don't. Last winter it definitely put on some size.

I have one that is supposed to turn a nice red color, but so far it's just green.

Maybe fall/winter temps will bring out the color for you. I haven't seen the red form, though I've heard of it.

Gigantea is also an excellent parent plants in crosses. I've got a hybrid with P. agnata, red form that a much better hybridizer than me produced and it shows some real promise.

Sub, does yours flower white? I was disappointed when mine flowered lavender as I really was looking forward to a white.

Nope, this one flowers lavender as well. I picked up 2 other clones, one of which is supposed to be the alba form, but I haven't seen it bloom yet. It's big enough that it should late winter/early spring, so hopefully I'll find out then. I'll propagate it as well, so if it's true to the tag I'll be in touch.

Why my Alfred Lau, and, propagations are flopping their leaves?. They are seated on a capillary mat, with a little oscillating fan, on a window sill without direct sunlight, temps are around 85F during the day, 77F at night, humidity is around 20%, but I don't trust this cheap barometer...lol. They were doing this since the last week, so, I added top water them, and a little light.
Any advice is welcome!. Thank you in advance.

Thx! Twill be much appreciated!

Hopefully the mother plant blooms this winter, and true to the tag!

Here's a current pic of my P. gigantea 'Red'. I was really starting to wonder what was up with it, sitting out in full sun all summer and looking as green as my other gigantea.

 

[adnedarn]

Cool! So the red did activate with the cooler weather.

 

[SubRosa]

Indeed it did!

 

[madrone]

Very cool - and good to know re: bringing out the red. Only have typical gigantea / Alfred Lau types myself, but have admired the red gigantea (at least from vendor sites). Nice to see it being grown well 'at home'.

 

[Rocketgirl]

Thank you for the advice.

Same plant today. For our non US friends, that portrait of Mr Washington is about 160mm long:

Impressive! Mine has never tried to get that big.
