ALSTROEMERIA 'Tesronto'

Commonly known as the Peruvian Lily, Alstroemeria 'Tesronto' is arguably one of the most ornamental of all the Alstroemeria hybrids and cultivars. It is noted for its gorgeous burned orange and yellow flowers which bloom against a backdrop of dark green-purple leaves making it is one of the most striking of all late summer flowering plants. There is some confusion with the cultivar name as it is can also be found under the perhaps more descriptive name of  Alstroemeria 'Indian Summer'.

Despite its exotic looks Alstroemeria 'Tesronto' is a frost hardy, deciduous herbaceous perennial making it a perfect, if not comparatively expensive, specimen for northern European gardens. It has an upright, and clump-forming habit with lance-shaped leaves. Under the right condition you can expect Alstroemeria 'Tesronto' to achieve an ultimate height of  between 60 - 100 cm in 2 -5 years.

The eye-catching, fiery blooms are produced early on in the summer but continue in succession until mid-autumn. The flowers open in funnel-shaped, cluster and are intricately marked with red tones and brown flecks on the inner petals.

Alstroemeria 'Tesronto' is protected by plant breeders rights and is not available from seed. Pot grown plant should be available in the spring but will need to be kept under protection until the threat of late frosts have passed. There is no reason why you cannot pot on established specimens into larger containers at his time.

Once the risk of late frosts has passed, plant Alstroemeria 'Tesronto' in a sunny or semi-shaded position in fertile, moist, well drained soil. If you wish to grow your Alstroemeria in a patio containers then use good quality soil based compost such as John Innes No.3.

Water regularly over the growing season and feed container grown plants with a water soluble plant fertilizer one a month. 

Old stems can be cut back to near ground level in late autumn and a dry mulch of bark chips, straw or bracken. This will help to protect the roots during extended periods of freezing weather. Container grown plants can be brought into a cool frost-free position.

Alstroemeria does not like to have its roots disturbed, but mature specimens can be divided in the autumn or spring if clumps become overcrowded.
