You're right... the Lc Netrasiri should be "Fireball." I just bought the same cross you have, and mine was spelled Lc Netrasiri 'Faiball' x Thihty 'Casen's Choice'. I can't find a picture of Thihty 'Casen's Choice' anywhere one the web, but "Fireball" is sort of a waxy mauve flower that seems to be all one color.
At any rate, I think the two make a gorgeous cross together. Mine actually looks like it's on fire... and the fragrance is absolutely AMAZING!!
Here's my Lc Netrasiri 'Fireball' x Thihty 'Casen's Choice':
I do vote that, for such a gorgeous plant, it should get a better name than that awkward cross. Someone register this flashy beauty with an appropriately flashy name, please! :-)
Oh, and considering you got yours as a bag baby from Lowe's, I am now completely convinced I paid about three times as much as I should have for mine at a nursery. Ah, well... I do love it!
