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 />

and stripes; variegated colour below, yellow green RHS<br />

152D; petiole fleshy, revolute. (Note: all RHS colour chart<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 />
