Forsythia a deciduous shrub which blooms February to April and has beautiful green foliage for the rest of the season. They can grow 8 to 12 feet high. You should prune established plants, cut down to the ground third of the branches that have bloomed, and get rid of old-growth. This keeps vigorous blooms each season.
The most popular species is Forsythia Intermedia Spectabilis which has this beautiful yellow display of blooms. The semi-pendulous Forsythia Suspensa makes a great shrub for planting against the north wall. For smaller gardens, there are Forsythia Ovata which grows to 5 ft.
I remember Forsythia since I was a child it was a symbol of spring and not only we had it in the garden but we would also purchase it as cut flowers to decorate the house. The bright yellow flowers were a welcome brightness after a dark and cold winter. sometimes the cut branches would start a root system in the vase and we would then plant it in the garden. The bright yellow blossoms of Forsythia are an excellent way to add colors to the garden specially in spring where before the leaves appear you have a splash of color. Forsythia is not hard to take care of and rewards you with beautiful flowers in spring and beautiful green bush for the rest of the year.
