LAVENDER
Lavandula stoechas ssp. pedunculata
‘Pukehou’
Application No: 96/140 Accepted 22 Jul 1996.
Applicant: Pukehou Nursery, Manakau, New Zealand.
Agent: Plant Growers Australia Pty Ltd, Wonga Park,
VIC.
Characteristics (Table 13, Figure 28) Plant: compact
aromatic shrub Stem: erect, pubescent. Leaf: short, linear,
strongly aromatic, pubescent, grey green (RHS 189B).
Inflorescence: terminal spike (mean length 37.9mm) with
basal flower whorl persistent below spike, conspicuous
large terminal bracts, oblanceolate, undulating margin,
purple (RHS 86D). Corolla dark purple (RHS 88A). (Note:
all RHS colour chart numbers refer to 1995 edition).
Origin and Breeding Open pollination followed by
seedling selection: ‘Pukehou’ arose as the result of a single
cycle of selection from a large number of open pollinated L.
stoechas ssp. pedunculata seedlings grown at applicant’s
property in Manakau, New Zealand. The open pollinated
seedlings were raised as part of a planned breeding program
to develop novel floral characteristics. The resultant
seedling selection has a unique flower colour, which is
darker than common L. stoechas ssp. pedunculata
seedlings. The selection has been propagated vegetatively
through many generations to confirm uniformity and
stability of its floral characteristics. Selection criteria: dark
bract and corolla colour. Propagation: ‘Pukehou’ is
commercially propagated by vegetative cuttings. Breeder:
Mary Robertson, Pukehou Nursery, Manakau, New
Zealand.
Choice of Comparators ‘Helmsdale’ A , ‘Magenta
Aurora’ A , ‘Marshwood’ A , ‘Major’ and ‘Merle’ were
initially considered as comparators. ‘Helmsdale’ A was
excluded because it is more compact in habit with shorter
internodes. ‘Magenta Aurora’ A was not finally considered
for its pink bract colour. ‘Major’ and ‘Merle’ both were
excluded because of their shorter flowering stem. Only
‘Marshwood’ A was finally chosen for its similarity in floral
characteristics. At the time of the trial this was considered
the most similar variety of common knowledge although
subsequent releases such as ‘Avonview’ would be more
appropriate comparators now. ‘Avonview’ can be easily
distinguished form ‘Pukehou’ on the basis of habit, leaf and
internode length and the consistent presence of a basal
whorl of florets below the spike in ‘Pukehou’ which is
absent in ‘Avonview’.
Comparative Trial Comparator: ‘Marshwood’ A . Location:
Wonga Park, VIC, Winter-Spring 1997. Conditions : plants
were propagated in Dec 1996 and raised in 150mm
containers in a pinebark-based medium with Osmocote,
grown outdoors under overhead irrigation. Trial design:
twenty plants of each variety were incorporated in the trial
with four random blocks of five plants. Measurements: one
sample per plant.
Prior Applications and Sales
No prior applications.
First sold in New Zealand in 1996. First sold in Australia in
1996.
