Acacia 'Gold Lace'

Acacia cardiophylla 'Gold Lace'

SYNONYM: Acacia 'Kuranga Gold Lace'

ORIGIN: Acacia 'Gold Lace' was selected for its prostrate growth habit in 1980 from seedlings of Acacia cardiophylla sown and grown on the breeder's property. The breeder is E P Clucas of Kuranga Native Nursery. Material has been vegetatively propagated since selection and further evaluated by the applicant for its growth characteristics.

DESCRIPTION: Acacia ' Gold Lace' is a perennial shrub with a trailing prostrate growth habit. Its flowering is observed to differ from the standard A. cardiophylla form. Flowering occurs from August to mid September, when the plants produce many mildly perfumed golden yellow globular heads about 1cm in diameter in dense ancillary racemes 3-5cm, long. The foliage of 'Kuranga Gold Lace' is typical A. cardiophylla and not observed to differ from the standard form. The stems' prostrate growth habit is the main characteristic distinguishing 'Kura nga Gold Lace' from other A. cardiophylla. The stems of 'Kuranga Gold Lace' also differ from those of the standard A. cardiophylla in becoming tortuous with age.

DIAGNOSIS: This variety is distinct from all other known varieties in having the following combination of characters: a prostrate trailing growth habit (attaining little more then 20cm height) with stems becoming slightly tortuous in age.

All characteristics described and comparisions are from comparative growing trials conducted at Wandin North, Victoria in 1989. Trials consisted of 25 plants 'Kuranga Gold Lace' grown from cuttings (potted January, 1989) with 25 plants grown from A. cardiophylla seed (sown August 1988 - potted January 1989), all in 15cm pots outdoors. Potting mixture was 'Debco' soilless mix. Measurements of 20 randomly selected plants were taken in April, 94 days after potting. Four year old tub grown plants of the variety were also measured.

CULTURE: Acacia 'Kuranga Gold Lace' is propagated vegetatively from cuttings. It is considered by the applicant to be suitable for growth outdoors in temperate regions of Australia. It is frost tolerant and requires a well drained soil.
