In the photos I see a Shadow in the middle looks like that growth is mature with 4 leaves. I think you have a spike on the way. Also the new growth is another sign you might have a spike since I have noticed on mine they send out new growth as they start to spike. So Give it a few months and you might have a spike.
sorry, all my pics go sideways!....this chu hua dancer has a spread of about 2', with thick strap leaves....it has bloomed beautifully like this for the past 6 years or so..i bought it from glen decker just on its first bloom cycle....lovely plant, thanks glen!
