A new cultivar of Gypsophila named ‘Pearl Blossom’ particularly characterized by vigorous growth potency and uniform flowering; high yields, especially after pruning; low artificial light requirements; relatively late flowering (9 to 10 weeks during summer and 14 to 15 weeks during late autumn); long, heavy, and stable branches that are of high quality year-round, pinching increases the stem number to a range of 7 to 9 heavy stems and up to 15 stems of medium size and weight; has big, white flowers that are full and of uniformly good quality year-round without distortion or color change; is convenient to harvest and use in floral arrangements; has a long vase life; and has good tolerance to Powdery Mildew, is disclosed.


Genus and species: Gypsophila paniculata L.

Variety denomination: ‘Pearl Blossom’.


The present invention comprises a new and distinct cultivar of Gypsophila, botanically known Gypsophila paniculata L., and hereinafter referred to by the cultivar name ‘Pearl Blossom’. ‘Pearl Blossom’ was discovered as a seedling resulting from an open pollination in April 2007 in Moshav Amioz, Negev, Israel among a group of unnamed Gypsophila paniculata L. plants. A single plant selection was subsequently chosen for further evaluation and for asexual propagation.

The new cultivar was first propagated in September 2007 in Moshav Amioz, Negev, Israel and has been asexually reproduced repeatedly by vegetative cuttings in Moshav Amioz, Negev, Israel for two years (approximately 10 generations). ‘Pearl Blossom’ has been found to retain its distinctive characteristics through successive asexual vegetative cuttings.

Plant Breeder's Rights for this cultivar have been applied for in Israel on Aug. 21, 2008. ‘Pearl Blossom’ has not been made publicly available more than one year prior to the filing date of this application.


The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal commercial practices in open field cultivation (soil) in Moshav Amioz, Negev, Israel.

    • 1. Vigorous growth potency and uniform flowering;
    • 2. Relatively late flowering, 9 to 10 weeks during summer, 14 to 15 weeks during late autumn;
    • 3. High yield, especially after pruning;
    • 4. Low artificial light requirements;
    • 5. Branches are stable, long, heavy, and of high quality all year round;
    • 6. Pinching increases the stem number to a range of 7 to 9 heavy stems, up to 15 stems of medium size and weight;
    • 7. Big, white flowers that are full and of uniformly good quality all year round without distortion or color change;
    • 8. Convenient to harvest and use in floral arrangements;
    • 9. Long vase life; and
    • 10. Good tolerance to Powdery Mildew.

This new Gypsophila plant is illustrated by the accompanying photographs. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a plant about 10 weeks old in August 2009 and grown from rooted cuttings in open field cultivation (soil) in Moshav Amioz, Negev, Israel under conditions which approximate those generally used in commercial practice.

FIG. 1 shows a flowering stem.

FIG. 2 shows a close up of the flowers and buds.


The following detailed descriptions set forth the distinctive characteristics of ‘Pearl Blossom’. The data which define these characteristics were collected from asexual reproductions carried out in Moshav Amioz, Negev, Israel during the summer of 2009. The plant history was taken on 10 week-old plants in open field cultivation (soil) that were pinched once on June 30, 2009. The color readings were determined under natural light. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).
