Growing peppers (sili) from seeds use pretty much the same method as growing tomatoes. I actually planted my hot pepper seeds the same time I planted my okra seeds, eggplants seeds, and tomato seeds.
Kai-lan, also known as Chinese broccoli, is a leaf vegetable featuring thick, flat, glossy blue-green leaves with thick stems and a small number of tiny, almost vestigial flower heads similar to those of broccoli. Broccoli and kai-lan belong to the same species Brassica oleracea, but kai-lan is in the group alboglabra [Latin albus+glabrus white and hairless]. Its flavor is very similar to that of broccoli, but a bit bitter. It is also noticeably stronger. Broccolini is a hybrid between broccoli and kai-lan, produced by Mann Packing Company, Inc.
