Callistemon 'Glasshouse Country'

ORIGIN: Callistemon 'Glasshouse Country' is an F2 selection from a hybrid cross between Callistemon sp. (Tinaroo) and C. salignus. A selection was made from a number of seedlings germinated from seed taken from a Calllistemon sp. (Tinaroo) plant in the mid 1960's. Seed was subsequently collected from these original plants, one of these seedlings being Callistemon 'Glasshouse Country'. The name 'Glasshouse Country' refers to the district in Landsborough Shire around the Glasshouse Mountains where the cultivar was first selected. The cultivar was first received by the Authority in March 1985. Registration applied for by Mrs E J Morgan of Glasshouse Mountains, Queensland.

DESCRIPTION: This cultivar grows to 3-5m tall by 1.5m wide. The growth habit is very upright. The trunk is covered in a soft fissured bark that is papery underneath. The mature foliage is rather stiff and prickly while the younger growth is paler and is covered with silky hairs. The young foliage is one of the features of this plant. The flower spikes are from 50-55mm long with some spring inflorescences reaching 70mm long by 40mm wide. The flowers are produced in the spring and autumn with occasional flowers during the summer. The anthers are a light gold in colour and the filaments are a deep pink.

DIAGNOSIS: This plant closely resembles C. salignus in most respects and it is difficult to distinguish it. The hybrid origin of the cultivar has been established only because the original seedlings were raised from seed taken from a plant of Callistemon sp. (Tinaroo). The leaves are slightly smaller than is usual for C. salignus, being up to 60mm long although often smaller. The ultimate height is also less. The bark is soft but fissured on the outside with papery bark underneath as compared to the papery bark of C. salignus. Otherwise, the general appearance is as for C. salignus. A similar cultivar form the same hybrid cross, Callistemon 'Glasshouse Gem' can be distinguished by its slightly lighter pink flower colour and its deep pink new growth.

CULTIVATION NOTES: The cultivation conditions required are as for C. salignus. Propagation of this plant must be by vegetative means to ensure retention of the cultivar features. The plant is tolerant of drought. Frost hardiness is not known though is suspected to be similar to C. salignus.

COLOUR CODE: RHS Colour Chart 1966

ADDITIONAL INFORMATION: Seed was originally collected off Callistemon sp. (Tinaroo) in the mid-1960's. C. salignus occurred naturally in the district and the resultant seedlings showed distinct characteristics of the latter species. Seed was collected from the better forms of the hybrid seedlings and plants were subsequently planted in the applicant's new garden in 1980. Callistemon 'Glasshouse Country' is the result of one of these seedlings. Mr WG Trapnell of Save The Trees Nursery in Zillmere examined some of the seedlings and concluded that Callistemon 'Glasshouse Country' had a good habit and attractive flower colour. The new growth was also attractive. Mr Trapnell is growing Callistemon 'Glasshouse Country' for sale through his nursery outlet.
