This deciduous shrub blooms with deep yellow flowers in areas usually too cold for most variety of forsythia. New Hampshire Golden Forsythia is finer branched and more compact than other forsythia, and it is an easy and excellent way to bring early color to your springtime landscape. This is a great choice if you live in a cold, windy spot. It is a shrub that grows up to seven feet high and up to eight feet wide, which is not as tall as other forsythia. Used as a border, it makes an excellent privacy screen. Its habit is drooping and mounded, and the blossoms arrive in late winter or early spring for a beautiful display of golden blossoms. The flowers bloom before the foliage appears. Weakly acidic soil is best, and the shrub thrives in U.S, Hardiness Zones 3-8. Privet plants works well with forsythia shrubs too. The dark green adds character to the yellow blooms.
It grows best in full sun and well-drained soil, but it tolerates a wide spectrum of growing conditions. It is deer resistant, pest resistant, and drought tolerant. This shrub grows quickly, and it is easy to plant and transplant. Planting a newly acquired forsythia in spring or early fall will ensure best growth. It should be planted far from buildings, walls and decks to allow roots and branches to spread freely. Monitor watering for the first two years, until the plant is well established. It will need to be watered weekly and deeply throughout the first growing season. After this point, it will be well enough established to survive without too much water maintenance. This Forsythia's companion plants include Blue Spruce, Privet and Fritillaria.
New Hampshire Gold Forsythia works well as a specimen, in a group or in mixed borders. The leaves will take on a surprising red and purple tint in the fall. For natural, early indoor color, the stems can be cut in winter and made to bloom indoors in water. No protection from the cold is necessary in winter. In the spring, apply a balanced fertilizer according to the package. Pruning one-third of the old wood after blooming will help the shrub maintain its shape and size. As with other forsythia, the buds grow in the summer and fall, and then open in the following springtime. This shrub does not produce significant fruit. New Hampshire Gold Forsythia is a cross between Korean Forsythia and Forsythia Hybrid 'Lynwood,' and was developed in New Hampshire. Its scientific name is Forsythia x New Hampshire Gold.
