Well your peacock certainly seems to be thriving. I'm sure by Friday, the mystery of the leaves and scapes will be solved. Everything the bulb needs to bloom is in the bulb. I've had bulbs bloom without a single root visible. Just because you don't see any roots on the Samba doesn't mean it won't put up new growth. The problem with a bulb not having roots is it isn't anchored well in the pot and can get very top-heavy. If the bulb doesn't have extra support, the whole thing can topple over and destroy the flowers, which is heartbreaking after waiting so long for the blooms. That has happened to me several times when I had pots sitting outside and a breeze came up. I go outside and discover an Amaryllis, which had no roots, laying on the ground, its fallen out of the pot. I think you said that your bulbs are sitting well down in the containers, and the containers are pretty heavy, so that should help in stabilizing things. That brings up another issue. I've learned the hard way that 4 or 6 inch plastic pots are just not heavy enough for Amaryllis, which have so much top growth. Its too easy for the whole pot to topple over. I switched over to clay pots for that reason.
