"Tall spike" is in its genes. L anceps on one side, the other side is a primary hybrid of two Laelias that used to be Schomburgkias - that have loooong spikes. Those buds will likely still take a month or 6 weeks or maybe more, but they're on their way. Not a plant for windowsill growing... Fortunately the footprint will stay fairly reasonable. I like the way you have secured the spike to the house!
