Personally, I think this variety of Pieris is great grown in a large container, using ericaceous compost. It will look terrific all year round, but especially at this time of year when it is beginning to flower. Long racemes of flamingo red lily of the valley type flowers adorn this plant. 'Valley Valentine' is wonderful planted with witch hazels and evergreen azaleas and hydrangeas.
Shade loving: All Pieris can tolerate shade quite well, and 'Valley Valentine' is no exception to this.
Some of my other favourite Pieris:
Pieris 'Forest Flame': New growth is brilliant scarlet red, often mixed with lighter shell pink leaves. I think the new foliage growth which appears after the white flowers, is as attractive as the flowers. This one is a cross between the japonica and forrestii types. Grows up to 6 to 8 feet.
Pieris 'Japonica': Lily-of-the-valley shrub. By far the most common one. Cascading white flowers are followed by pink to bronze new growth. Ultimate growth can be up to ten feet, unless pruned.
Pieris japonica 'Mountain Fire': Brilliant red new foliage growth, turns dark green with maturity. Drooping clusters of showy white spring flowers. Grows up to 6 feet tall.
Pieris japonica 'Variegata': This one is best known for the attractive leaves that are green with white margins. Drooping flower clusters are white. Ultimate growth is about 5 feet.
