Simple to grow! These seeds originated from Thomas Jefferson's Monticello, purchased in 1995. We have been growing them ever since. It's very hard to find celosia like this that isn't hybridized. Fortunately we grow isolated plants to keep the strain true to the original giants. We have won many awards with these amazing flowers. This celosia is also particularly notable for retaining it's color when dried. This makes it an excellent addition to dried flower arrangements and wreaths!
