‘June’<br />
Application No: 97/238 Accepted: 24 Oct 1997.<br />
Applicant: Notcutts Nurseries, Woodbridge, Suffolk, UK.<br />
Agent: Plants Management <strong>Australia</strong> Pty Ltd, Warragul,<br />
VIC.<br />
Characteristics (Table 22, Figure 36) Plant: compact,<br />
rhizomatous, clump forming, herbaceous perennial. Stem:<br />
absent, with leaves radical in a basal mount. Leaf: flat to<br />
slightly undulate, petiolate, glabrous, glossy, ovate to<br />
lanceolate, apex acute, entire, variegated; veins prominent<br />
beneath, flat above; ground colour above, a mixture of<br />
greyed green (RHS 189A) and yellow green (RHS 147A-<br />
B), arranged at the margins and in stripes; variegated colour<br />
above is prominently green yellow (RHS 151A); ground<br />
colour below is greyed green (RHS 191A) at the margins<br />
and stripes; variegated colour below, yellow green RHS<br />
152D; petiole fleshy, revolute. (Note: all RHS colour chart<br />
numbers refer to 1986 edition.)<br />
Origin and Breeding Spontaneous mutation: of Hosta<br />
‘Halcyon’. The parental variety is characterised by compact<br />
growth habit but with non-variegated leaves. A variegated<br />
mutation was observed in breeder’s property in Lancashire,<br />
UK. The central tip of the mutation was excised and placed<br />
in tissue culture and selected through several generations to<br />
confirm the uniformity and stability of the original<br />
selection. Selection criteria: variegated foliage colour.<br />
Propagation: ‘June’ is commercially propagated by tissue<br />
culture. Breeder: Neo Plants Ltd, Freckleton, Lancashire,<br />
UK.<br />
Choice of Comparators ‘Halcyon’ was selected, as it is the<br />
parental variety from which the candidate variety was<br />
developed. ‘Gold Standard’ was selected on the basis that it<br />
is the closest in appearance of known varieties of common<br />
knowledge.<br />
Comparative Trial Comparators: ‘Halcyon’ and ‘Gold<br />
Standard’. Location: Nilma North (Lat. 38°S) VIC.<br />
Conditions: ambient under 50% shade; ‘June’ was raised<br />
from tissue culture and ‘Halcyon’ and ‘Gold Standard’ from<br />
division, all plants were grown in 70mm tubes from Sep<br />
1998 and transferred to 150 mm pots in Sep 1999 in a<br />
standard soilless media fertilised with controlled release<br />
fertiliser. Trial design: randomised block. Measurements:<br />
ten to twenty specimens selected from ten plants; time of<br />
measurement Feb 2000.<br />
