Example

[0018]The plants shown in the figures are approximately 50 weeks old. The plant started out as cuttings, taken from the stem of a grown plant.

[0019]‘Grace’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length. Color determinations were made with The Royal Horticultural Society (R.H.S.) Colour Chart.

THE PLANT

[0020]Origin: Controlled cross. The new cultivar originated as a seedling from a controlled cross between the unpatented variety known as LK49 which was the seed parent and the commercial variety ‘Amsterdam’—non-patented—which was the pollen parent.[0021]Form: Upright, compact shrub. A typical plant with a mature inflorescence that is ready for sale is approximately 23″ high (with stakes) and has a diameter of 20″ when grown in a 6″ pot with appropriate soil amendments. The pictured plant had three stems with one inflorescence per stem with 1 cutti...

Abstract

A new and distinct cultivar of Hydrangea macrophylla (Thunb.) named ‘Grace’ originated as a controlled cross between unpatented varieties. The cultivar ‘Grace’ can be blue or red depending on the acidity of the soil and the presence of aluminum, but is preferably grown as a red variety. The variety ‘Grace’ has large attractive inflorescences with large sepalous florets, distinct sepal pigmentation and good tolerance to cold temperatures. The upperside of the sepals is R.H.S. 63 A (red-purple group), the underside of the sepals is R.H.S. 63 D (red-purple group)

Description

[0001]Botanical classification: Hydrangea macrophylla (Thunb.) ‘Grace’.[0002]Variety denomination: ‘Grace’.BACKGROUND OF THE INVENTION[0003]This invention relates to a new and distinct cultivar of the Saxifragaceae family. The botanical name of the plant is Hydrangea macrophylla (Thunb.) ‘Grace’.[0004]The new cultivar originated as a seedling from a controlled cross between the unpatented variety known as ‘LK49’ which was the seed parent and the commercial variety ‘Amsterdam’—non-patented—which was the pollen parent. ‘LK49’ is relatively compact plant with wiry stems, relatively small leaves, relatively small sepalous florets, and inflorescences that are resistant to being damaged by conditions in commercial coolers. ‘Amsterdam’ is a relatively compact plant with relatively thick stems, relatively large leaves, and medium sized sepalous florets. The inflorescences of ‘Amsterdam’ are not particularly resistant to being damaged by conditions in commercial coolers. The leaves or ‘Grace...
