First C. Walkeriana Flower of the Season - ‘Mirtha Isabel Oliveros'

I've grown indoors about half the time over the years and greenhouse the other half. I confess that I have had mixed results getting walkeriana to flower indoors. Some articles I've seen say that the primary reason this species fails to flower is insufficient light. I think this is likely because there are other day length orchids that are easier to flower. If you use lights, be sure to have the on time vary with the actual day lengths.

That said, one problem with this hobby is that asking 10 people you can get 10 opinions. The one thing I think we can say for sure is that a lot of people have trouble getting them to flower.

My suggestion, for what it's worth, is to buy a mature plant of high quality of a well-known variety other people have had success with, then give it a try. See if it flowers for you next year.

I can't say why, but I find walkeriana to be more interesting orchids than their larger cousins. I like growing them even when they don't flower.

Really kicking myself I didn't buy a "manhattan blue" last year when it was available.

I did get a Cattleya Final Blue. That is 75% walkeriana, not quite the right one but a nice one does seem to be quite rare.

I'm not fond of the blue walkers because the flowers are of significantly lower quality than most others. Actually, I find the blue cattleyas unimpressive in general.

I also have a Tokyo #1 from Krull Smith that was a surprisingly nice three plants, though it hasn't flowered (yet?) this fall.

If anyone is interested a couple of these nurseries sell through facebook and I am quite happy with them.

Interest here.

Missed that you are in the UK. I have a 'Manhattan Blue' its a nice coerulea with great color and vigor, but not the pinnacle of walkeriana breeding.

It might be worth investigating importing some if you are really wanting a nice coerulea or other uncommon color forms.

I had a good experience importing a bunch of walkerianas from Orquidário Americana. Free shipping, good communication, no paperwork (may be different for you), and 1k order minimum.

I got a 4 bulb division with a spike that looks like this for $250

This photo shows that the Brazilians are light years ahead of us in terms of line breeding, including coerulea walkeriana. This is nearly as good a shape as any tipo.

I asked Dwayne Johnson if he could find me a Brazilian Jewel.

He said he only does that in movies.
