Special Attributes

'Cardinal' is a mophead Hydrangea that produces deep pink flowers that fade to red. Flowers are more red in acid soil conditions. Flowers are a standout in the garden during summer and are excellent for cutting and use in fresh or dried flower arrangements. The leaves are beautiful green and turn a lovely purple in the fall. Cardinal is a fast grower to about 4 to 5 feet in height and wide in 3 years.




Landscape & Garden Uses

Growing in a rounded mound 4 to 5 feet tall and wide, Cardinal Red Hydrangea is ideal for use as an accent, in groupings, or as a colorful hedge in landscape borders and home foundation plantings. A fine addition to cut flower gardens, cottage gardens and Hydrangea gardens.

Suggested Spacing:  3 to 4 feet apart for solid hedges;  8 feet or more apart for space between plants





Cultural Preferences

Cardinal Red Hydrangea is easy to grow in a moist but well-drained soil in full sun to part shade, depending on your climate. Plants will tolerate full sun in northern zones however appreciate some afternoon shade or filtered sun in warmer southern zones. We suggest at least 5 hours of direct sunlight per day or all day lightly filtered sun for best flowering. Mophead-type Hydrangea produce blooms only on old wood (growth from the previous year). This means that even though it is tempting to cut them back in the winter, when they are only bare sticks jutting out of the ground, don't do it. The flower buds are already formed and hidden in those bare sticks, so don't cut them off if you want flowers! 

Note:  Cardinal Red is a Hydrangea macrophylla species that produces its flowers from buds that formed on "old wood" (during the previous year). This means that even though it is tempting to cut them back in the winter, when they are only bare sticks jutting out of the ground, don't do it. The flower buds are already formed and hidden in those bare sticks, so don't cut them off if you want flowers.
