More information

A compact habit flower, with stems of 55cm (22in) that do not require staking. They bear daisy-like flowers of 5cm (2in) throughout the summer, shiny and golden around an orange heart. This perennial is closely related to Helianthus, the famous sunflower, to which it bears a strong resemblance. Not demanding, resistant to powdery mildew, it can be easily grown in any well-drained soil, in full sun or partial shade. Its vigour and simplicity make it suitable for stem flower arrangements, in the garden, in flower pots, but also in vases.

Description

Heliopsis helianthoides 'Tuscan Sun'® is the smallest cultivar of false sunflower available to date. This cousin of the sunflower forms a clump of neatly leafed stems and is adorned with a very long summer flowering period, both unassuming and full of good cheer. Its daisy-like flowers in warm golden yellow with an orange centre shine like little suns. This compact and branched variety, well suited to container gardening, is also more resistant to powdery mildew. Plant Heliopsis, they are excellent perennials for wildflower gardens, whose cultivation is within the reach of all gardeners, even beginners! 

 

Heliopsis belongs to the Asteraceae family. H. helianthoides, from which this new variety 'Tuscan Sun' originates, is native to North America, where it is usually found in open woodlands and tall grass prairies.

'Tuscan Sun' is a perennial plant with non-spreading woody roots. It forms a bushy clump, made up of many strong and well-branched stems, not exceeding 55-60 cm (22-24in) in height  with a spread that is almost equivalent.  Its growth is moderate to fast. Flowering occurs from June to September if faded flowers are regularly removed. The inflorescence appears at the end of each stem and consists of several heads (flower heads), 5 to 6cm (2in) wide. The flower heads bear golden yellow ray florets, arranged in a collar around a beautiful rounded orange central disc that turns brown in autumn. After the flowers, which are highly visited by insects, come seeds that birds love.  The foliage is distributed up to the top of the stems, it is bright green, rough, the leaves are 10cm (4in) long, lanceolate and dentate, somewhat cordate. The vegetation disappears in winter and regrows each spring from the stump.

 

Trends are quite inscrutable because the upright habit of Heliopsis, its long flowering period and its low requirements, are all keys that should open the door to every garden... but no! However, all specialists agree that they are excellent plants. 25 years ago, Alan Bloom, a famous perennial plant breeder in England, said: "These are certainly the last plants I would part with if I decided to eliminate the yellow colour from the borders in my garden". Combine 'Tuscan Sun' Heliopsis with other easy-going and exuberant perennials or annuals in wildflower gardens and sunny borders, such as mulleins, Scabious, dwarf daisies, Buenos Aires Verbenas, love-in-a-mist, and Cosmos, for example. It is a very good plant for flowering containers and homemade bouquets.

Planting and care

The false sunflower is an easy-to-grow plant. It adapts to any well-drained soil and only fears excessive winter humidity and slightly dry soil in summer. However, it tolerates clayey, poor, and occasionally dry soils. The 'Tuscan Sun' Heliopsis helianthoides prefers a sunny exposure, but it tolerates partial shade, which will give it a slightly looser habit. This compact variety does not require staking and is resistant to wind. It is preferable to deadhead the flowers to promote a second flowering. The plant can be divided every 2 to 3 years to maintain its vigour. You can also cut the plant back by half in early June to promote the strength of the clump.

Note that some varieties of Heliopsis are susceptible to powdery mildew and rust when growing conditions are not optimal. A preventive treatment against fungal diseases should be carried out towards the end of winter. Afterwards, treatment should only be applied if necessary, in case of confirmed presence of parasites on the plant, using targeted treatments whenever possible. In any case, it is important to avoid any treatment during flowering to avoid harming pollinating insects.
