PLANT VARIETIES JOURNAL 2000 VOL 13 NO. 1 a full-sib of ‘Lindwall’, while ‘Gairdner’ A (Onslow//Triumph/Shannon) is related to ‘Lindwall’ through the common parent ‘Triumph’. The parents of ‘Lindwall’ (‘Triumph’ and ‘Grimmett’) were also included in the trial. Comparative Trial Comparator(s): ‘Gairdner’ A , ‘Gilbert’, ‘Tallon’, ‘Triumph’, ‘Grimmett’. Location: Hermitage Research Station, via Warwick, QLD (28° 12´ 45´´S 152° 06´ 15´´E). Conditions: sown into a deep cracking black clay soil on Jul 2nd, 1999. Sowing Rate 60,000 plants/ha. No irrigation applied. The trial was subjected to light moisture stress prior to anthesis (during Jul-Aug, 1999). A light infection with powdery mildew (Erisyphe graminis) was observed on susceptible cultivar ‘Grimmett’. Trial design: a 3-replicate latinised row column design. Measurements: 30 random plants sampled per trial entry per characteristic (10 observations per replicate). Prior Applications and Sales No prior applications. First sold in Australia in 1997.

Applicant: Notcutts Nurseries, Woodbridge, Suffolk, UK. Agent: Plants Management Australia Pty Ltd, Warragul, VIC. Characteristics (Table 22, Figure 36) Plant: compact, rhizomatous, clump forming, herbaceous perennial. Stem: absent, with leaves radical in a basal mount. Leaf: flat to slightly undulate, petiolate, glabrous, glossy, ovate to lanceolate, apex acute, entire, variegated; veins prominent beneath, flat above; ground colour above, a mixture of greyed green (RHS 189A) and yellow green (RHS 147A- B), arranged at the margins and in stripes; variegated colour above is prominently green yellow (RHS 151A); ground colour below is greyed green (RHS 191A) at the margins and stripes; variegated colour below, yellow green RHS 152D; petiole fleshy, revolute. (Note: all RHS colour chart numbers refer to 1986 edition.) Origin and Breeding Spontaneous mutation: of Hosta ‘Halcyon’. The parental variety is characterised by compact growth habit but with non-variegated leaves. A variegated mutation was observed in breeder’s property in Lancashire, UK. The central tip of the mutation was excised and placed in tissue culture and selected through several generations to confirm the uniformity and stability of the original selection. Selection criteria: variegated foliage colour. Propagation: ‘June’ is commercially propagated by tissue culture. Breeder: Neo Plants Ltd, Freckleton, Lancashire, UK. Choice of Comparators ‘Halcyon’ was selected, as it is the parental variety from which the candidate variety was developed. ‘Gold Standard’ was selected on the basis that it is the closest in appearance of known varieties of common knowledge. Comparative Trial Comparators: ‘Halcyon’ and ‘Gold Standard’. Location: Nilma North (Lat. 38°S) VIC. Conditions: ambient under 50% shade; ‘June’ was raised from tissue culture and ‘Halcyon’ and ‘Gold Standard’ from division, all plants were grown in 70mm tubes from Sep 1998 and transferred to 150 mm pots in Sep 1999 in a standard soilless media fertilised with controlled release fertiliser. Trial design: randomised block. Measurements: ten to twenty specimens selected from ten plants; time of measurement Feb 2000. Prior Applications and Sales Country Year Current status Name Applied UK 1991 Granted ‘June’ The Netherlands 1992 Granted ‘June’ EU 1996 Granted ‘June’ ‘June’ was first sold in UK in November 1993.
