Mandelbrot’s Family Heirlooms is the name given to our high-end line of seeds. This title and the lengthy process required to produce these boutique seeds is reserved for our most coveted lines. They were meticulously refined over many generations to lock in the desirable traits they were bred for. These seeds, refined by Mandelbrot himself, offer something truly special in their attributes and are guaranteed to produce a stable and consistently positive result. They come with a higher price point and a satisfaction guarantee. We feel it’s important to make our customers aware of the different intended applications of our two lines of products.
