GOLDILOCKS or GOLD CURL is a new forsythia cultivar that is noted for its compact shape with short internodes, abundant early spring flowering, dark green foliage that begins to emerge during flowering, good winter hardiness and suitability for containers. It is a small, upright, deciduous shrub that typically grows to only 2-3’ tall with a slightly larger spread. Golden flowers clustered around the stems bloom in profusion in late winter to early spring. Ovate leaves are dark green in summer. GOLDILOCKS is the product of certain experiments in Angers, France, in which plants of Forsythia x intermedia ‘Spring Glory’ were irradiated with gamma rays. Seed from subsequent open pollination was collected and planted, and one of the resulting seedlings was named ‘Courtacour’. It should be further noted that this cultivar is listed by The Royal Horticultural Society (RHS) under the French trade name of BOUCLE D’OR. BOUCLE D’OR or ‘Courtacour’ is in turn sold in the U.S. under trade names of GOLD CURL and GOLDILOCKS. U. S. Plant Patent Applied For (PPAF).
No serious insect or disease problems. Some susceptibility to leaf spot and crown gall. Although vegetatively winter hardy to USDA Zone 5, the flower buds are sometimes damaged by cold winter temperatures and late freezes in Zone 5.
