littlekirstenjr, I cannot recall seeing a 'crown of thorns' blooming in a truly indoor environment.
They do well in well-lit atriums and shaded sidewalks; I suspect that it has to do with light intensity.

Of course they will bloom indoors, but you need sun! Do you have sun?

I have two...one with large leaves, and one with small leaves. The large-leafed milii is not blooming; the small-leafed is.

Hi Folks,

There's been a couple of threads about this pretty recently. I've commented on several & shared tips. Sorry I don't how how to provide links to them, but I believe the last discussion was with someone named Danielle & referred to COT in the title.

I've got 5 now I think, 2 in bloom now, here's one now.

Rona, this small plant blooms in a west window in NYC, pretty Indoor to me.

Thanks for they replies. Yes, the plant is in a south facing window and gets all day sun from morning to sunset. Perhaps there simply might not be enough hours of daylight in the winter? I'm not sure what else.

It seems relatively happy and healthy with new growth appearing in several parts of the plant. Just hasn't bloomed for months. See below.

Thanks pirate_girl. I'll take a look at your posts.

here's mine.
pot size is about 3 inches in diameter, medium is coarse builder's sand with pumice and about .5 grams of osmocote plus added.
the little guy gets full sun everyday.

i usually forget the plant and it stays bone dry for weeks but it's always full of cythea.

Hey Kirsten,

Turns out my prior post to which I'm referring is at the Cactus & Succulent site (next door, sort of, if you see top of this page). I can't quite tell what the mix is (looks rather peaty).

Am guessing (as in the post to which I'm referring), it wants more water (see the other post for explanation of why this is & would be OK). You'd probably need to change that mix too (to much more fast draining) to be able to water more.

Hey Keylyn,

Quite a bunch of blooms you've got there! Was thinking you'd be either in FL or CA given how tropical that growth looks -- I see you're in Australia, no wonder such lush growth, nice growing! Interesting markings on those buds, I haven't seen that before.

I have a red (bloom color) one & a smaller, white one ('Apache'?) sitting on a very cold (in winter - heat turned down to 50 at night) window sill in front of east-facing tinted windows that only allow 47% light transmission. They both have blooms now and throughout the rest of the growth cycle, though the white one is much more generous in offering up its blooms.

I wanted to know if there's anything I can do to help it bloom again. Don't be tempted to use a 'bloom booster' fertilizer, or any fertilizer with a higher P (middle number) content than either the first or third number. IOW - there should be more N and K than P. Make sure you're using a soil you can water until past the point of total soil saturation whenever you water, w/o having to worry about root rot or impaired root function. Plenty of light and warmth is what they like best, but you can see by what I offered above that they really aren't all that fussy, as long as you don't over-water.

BTW - most people are mildly to severely allergic to the toxic sap. I'm in the middle, but I can count on blisters like you get from poison ivy and lots of itchiness if I don't get the sap off immediately. I cut these plants back regularly - they look much nicer in a bush form, in my estimation.

This one keeps blooming, nonstop...red flowers in summer:

same plant after being inside for couple of months - I like the colors here:

and again this fall, still blooming the same even now. Planning on cutting it back as Al mentioned, to - hopefully - get a bush. I wonder if it stops blooming after being cut.
Rina

Nice!
I plan on whacking my E. milii, too.

While not as impressive as many of the ones already featured-- my little guy has started blooming Thought I'd share and update!

Lil K jr

It looks wonderful! Congrats! :-)

Josh

Looks pretty impressive from here, am happy for you. Nice work, Enjoy!
