Well, I was going to say about the same as Zach. You said it was growing rather fast, which is good, but malipoense tends to have such a tall spike so it could be a while. Though, delenatii might speed it up a little, and make it a little bit easier to bloom.
Strangely...I just had a dream about this. I was in the kitchen (my kitchen so I don't know how your plant got there John...) and I was doing some mundane thing, and I glanced over at your Lynnleigh, and the spike was growing, like, audibly growing, as in Jack and the Beanstalk or, rather, like Pinocchio's nose....it grew like three inches and stopped and I thought, "Boy, John wasn't kidding, his spike really *is* growing fast!"
