    This dwarf cultivar of the Greenstem Forsythia is still sold occasionally at many conventional nurseries in the Midwest, the Mid-Atlantic, and the Northeast USA. It tends to be used more by landscape architects & designers than the general public. I see it occasionally in some public and professional landscapes. I don't find it to be wonderful plant. Back in the Chicago Region in Zone 5a in the 1970's into the 1990's it often did not bloom well from flower buds killed during a strong winter, unless they were sheltered by snow. In Zone 6 and higher it tends to bloom well. It has no fall colour like other forsythias. I remember one person in the past digging one out of the ground because she did not like how it got untidy when older; it needs lots of selective pruning to keep looking good.
