Burgundy Lace Filbert

Corylus avellana 'Burgundy Lace' (USPP28216) is a named European hazelnut selection grown chiefly for its deeply cut burgundy foliage. The patent identifies the cultivar as 'Burgundy Lace' and describes moderate vigor with an upright-spreading habit ([USPP28216P3](https://patents.google.com/patent/USPP28216P3/en)). ## Foliage and form The patented selection develops dark burgundy leaves through spring and summer, with burgundy leaf buds and catkins ([USPP28216P3](https://patents.google.com/patent/USPP28216P3/en)). Patent observations describe plants reaching about 5 metres in height and spread; use this as an indication that the shrub can become substantial, not as a guaranteed landscape measurement. ## Flowering and nuts The patent describes small abnormal catkins that produce little pollen, late pollen shed and female receptivity, and incompatibility alleles S6 and S20 ([USPP28216P3](https://patents.google.com/patent/USPP28216P3/en)). Nut production therefore depends on a compatible, well-timed pollen source; do not assume this plant is a reliable pollinizer for every hazelnut. The patent calls the nuts edible but reports small nuts, low yield, and noncommercial kernel quality, so the crop is secondary to the ornamental display ([USPP28216P3](https://patents.google.com/patent/USPP28216P3/en)). ## Disease The patent reports resistance to eastern filbert blight associated with a Gasaway-derived resistance allele ([USPP28216P3](https://patents.google.com/patent/USPP28216P3/en)). Resistance is not immunity, and the patent does not guarantee performance against every disease strain or at every site. ## Maintenance Allow room for the mature form and retain the distinctive foliage when pruning.
