Nursery contributed plant descriptions

Clark' is unique in that is it precocious (early maturing) so you can start harvesting the delicious buttery nuts earlier, the nuts are smaller, but have a good nut to shell ratio and are well-suited to commercial or home growers; it has a very upright growth habit that makes it better suited for smaller spaces and you can plant these more densely than other cultivars; another great introduction from Oregon State University, Filberts need a partner to produce fruit Halls Giant is the best partner for Clark.
