General Description:

Leptospermum is a genus of about 83 species, all but three occurring in Australia. They are commonly known as ‘tea trees’ due to the practice of early European settlers of using the leaves of some species as a tea substitute.

Leptospermum ‘Rhiannon’ is one of a number of colourful cultivars developed at Bywong Nursery at Bungendore, New South Wales. It is a hybrid between between Leptospermum rotundifolium and Leptospermum spectabile. L. ‘Rhiannon’ is a medium shrub which grows to about 2 metres high with an upright growth habit. It has narrow, lance-shaped leaves to about 10 mm long. The 5-petalled, mauve-pink flowers are larger than is typical for the genus being about 20 mm diameter with numerous small stamens surrounding the central stigma. The flowers have a green centre and are followed by woody fruits containing many seeds; the fruits remain unopened until they are removed from the plant or the plant dies.

Leptospermum ‘Rhiannon’ is a very attractive cultivar which should become very popular in cultivation. Based on the characteristics of its parents, the cultivar can be expected to be a hardy shrub for moist soils in temperate climates. Plants prefer full sun or partial shade and should be pruned after flowering to promote dense growth and promote flowering for the next season. The flowers which arrear in spring are reported to be long lasting and suitable for use as a cut flower.

To retain the characteristics of the cultivar, propagation by cuttings is needed. Cuttings of hardened, current season’s growth strike readily. Propagation is easy from seed but seedlings will vary in characteristics from the cultivar and cannot be named ‘Rhiannon’.
