Description

Calibrachoa Superbells® Unique 'Wisteria Star' is a mini-petunia with lavender flowers finely veined in purple around a yellow eye, ideal for hanging baskets, window boxes and large containers on terraces and balconies. It is a well-branched variety, with a rounded then trailing habit, which flowers from May until the first frosts. This plant quickly and easily forms a pretty dome covered in flowers.

Calibrachoas, or Million Bells, are tender perennial plants grown as annuals. Very close to petunias, they differ by a few morphological characteristics; their flowers are smaller, their vegetation is of a herbaceous plant with a woody base type, their development is less significant, and they are more drought-tolerant. They belong to the Solanaceae family like tomatoes.
The Superbells® range and the Superbells® Unique series are developed in a network between Japanese breeders and European producers. They offer reliable varieties for window boxes and hanging baskets, presenting well-branched growth, uniform flowering and good performance under varied growing conditions, with better disease resistance than older calibrachoas. The Unique series brings together compact, regular, easy-to-grow young plants, with clear colours, often bicolour or star-shaped.
'Wisteria Star' belongs to this group of star-shaped calibrachoas; its light lavender to lavender-purple corolla has a radial purple pattern that forms a star around a golden yellow heart, reminiscent of wisteria clusters. In one season, the plant reaches 20 to 30 cm in height with a spread of 40 to 50 cm, its stems can trail 25 to 30 cm in a hanging basket. The fine, well-branched stems, slightly woody at the base, bear small, medium green, slightly sticky, ovate to spatulate leaves 1 to 3 cm long. The funnel-shaped, 2 to 3 cm diameter flowers open all along the stems, from May to October. This variety is largely self-cleaning: spent flowers dry and fall off by themselves. In practice, this mini-petunia is grown in a well-draining, rich and fresh potting compost, with liquid fertiliser applications every one to two weeks and a minimum of 5 to 6 hours of sun per day.

Calibrachoa Superbells® Unique 'Wisteria Star' is used mainly in hanging baskets or in deep window boxes, where its stems can trail freely and hide the edge of the container. You can combine it with Calibrachoa Superbells 'Cherry Star' with pink and yellow flowers, or Calibrachoa Superbells Unique 'White', which will highlight its lavender hues. In a large window box, it can be enhanced by trailing plants like Dichondra ‘Silver Falls’ or Helichrysum petiolare ‘Silver’.

Note: Please note, plug plants are products reserved for experienced gardeners: upon receipt, pot them on and store them under cover (conservatory, greenhouse, cold frame...) at a temperature above 14°C for a few weeks before being placed outdoors once all risk of frost has passed.

Planting and care

You can plant your Superbells Unique Wisteria Star calibrachoas in the ground or in pots. If you wish to plant them in the ground, wait until the last true frosts have passed. In the meantime, you can grow them on in pots in a warm, bright spot.
Plant them in a sunny, sheltered position. They require light, humus-bearing, and well-draining soil. Avoid overwatering at the start of the growing season, as they are sensitive to excess moisture. They can tolerate some drought but will need regular watering during intense summer heat, especially in containers.
They are very floriferous and fast-growing, hungry plants. We recommend feeding them with a liquid fertiliser for surfinias once or twice a week during the growth period. Remove faded flowers and dry leaves as needed to maintain their attractive appearance and prolong flowering.
