Bill, you have a really beautiful plant here! Congrats on the gorgeous blooms! How old is your plant? What caught my eye were the leafless p.bulbs. I also have a burana beauty - an older bushy plant I bought some 5 or 6 years ago and it doesn't have a single leafless p.bulb yet... I wonder what would be more typical of this plant - for the p.bulbs to keep the leaves or to go leafless? Maybe fellow burana growers will also chime in with their observations?
Here's my plant:
