Tabebuia tree seeds

Tabebuia tree seeds

Ok. I obtained some papery seeds from a Tabebuia pod. I planted some in a container with potting mix to see what would come up. This is what the mature tree looks like when it is in bloom. Does anyone know how long it takes the seeds to sprout? I'm in zone 9 so it's definitely warm enough down here for it to grow. I'd love to have some of the beautiful trees but it's been over a month and I'm still looking at an empty pot. I've got a bag full of these little seeds, do the majority just not make it? Please help.
