Tienito, I believe we a local strains here for a lot of bulb flowers, due to the local climate. E.g. I have a local Narcissus , and Narcissus that I bought in Europe. I planed both of them this winter in similar soil. Local one has already 6-7 inches leaves, Europe one has barely a inch long. Same all other plants. Only Pancratium maritimum will bloom first (before the rain ,in the end of the summer without any leaves) , and then in winter it will grow green leaves.
At least amaryllis grows all year around, and increase size of the bulb very quickly. It can grow from miniature bulb of about an inch in diameter to big bulb , 2 inches in diameter in one summer year (even less, mine grown from April to September). I heard that Beladona blooming here in the end of the summer, I will check it out,
