More information

The corollas of this Black-eyed Susan, with a black centre, display a very bright cherry red colour that becomes more pink as they ripen. It is a climbing perennial plant of modest size, sensitive to the cold, grown as an annual in our climate, which blooms from May-June to October. Its stems, covered with lush foliage, cling to trellises in large pots, wander through flowerbeds, or generously cascade from hanging baskets.

Description

The Thunbergia alata 'Sunny Suzy Cherry' is another Black-eyed Susan from the 'Sunny Suzy' series that brings together early, floriferous varieties with various colours. With a moderate habit, 'Cherry' offers intense red flowers for almost 5 months that open around an almost black centre. Perennial in theory, it is an adorable annual climbing plant in our climates. Its stems covered with lush foliage cling to trellises on their own, allowing for the quick creation of large and decorative pots or stunning hanging baskets that can be kept in the conservatory. It appreciates heat and sunlight, fertile, moist, and well-drained soil.

The Thunbergia alata 'Sunny Suzy Cherry' is a fast-growing, perennial, and voluble climbing plant that tolerates only very light frosts (-3 °C (26.6°F)). The species is native to tropical regions of East Africa. It is grown as an annual in our climates. The cultivar 'Sunny Suzy Cherry' reaches an average height of 1.40 m (5ft) and a width of 50-60 cm (20-24in) in just a few months. Its stems twine around their support. They are adorned with lush, dark green foliage, consisting of evergreen (except in frost) and villous leaves with dentate edges, shaped like a heart or an arrow. The flowering, quite early for a Black-eyed Susan, extends from late May-early June to October. The 3-4 cm (1-2in) flowers, enclosed in a villous calyx, are borne on peduncles in the axil of the leaves. The corolla is tubular at the base and extends into five spreading lobes. The colour of the flowers slightly changes as they ripen, ranging from cherry red to a slightly more pinkish red. In the centre of this flower shines a beautiful, characteristic blackish-violet eye. Its role is to attract pollinating insects that visit the flowers with enthusiasm.

The 'Sunny Suzy Cherry' Black-eyed Susan is suitable for both container and open ground cultivation for seasonal decorations, in sunny locations. Climbing, voluble, and lightweight, it pairs well with all 'Sunny Suzy' Black-eyed Susans. It can also be planted next to a perennial climbing plant such as a herbaceous clematis. It can also be used as ground cover. You can associate it with summer-flowering bulbs, such as gladioli: it will twist around their leaves and bloom in the most unlikely places, adding a touch of whimsy to rigid flower beds. It will also make a great impact in a large hanging basket.

Note: Our plug plants are professional products intended for experienced gardeners: upon receipt, transplant and store them in shelter (conservatory, greenhouse, cold frame etc.) at a temperature above 14°C (57.2°F) for a few weeks before being planted outdoors once the risk of frost is definitively passed.

Planting and care

You can plant your 'Sunny Suzy Cherry' Thunbergia alata in the ground or in a pot. If you plant them in the ground, it is imperative to wait until the last frost has passed (Thunbergia cannot tolerate frost and do not handle temperatures below 8° (46.4°F) well). In the meantime, you can prepare them in a pot in a warm and bright place to accelerate their growth.

Plant your Black-eyed Susan in a hot, sunny location. They need a light and humus-bearing soil and warmth. They tolerate short periods of drought fairly well, but will need regular watering during hot summer temperatures to flower well. In pots, they must be watered very regularly. Very floriferous and with rapid growth, they can reach 2m (7ft) in a single summer. Remember to provide support if you use them as climbing plants. Usually grown as annuals, they are actually very tender perennials: by bringing them indoors in September, you can extend their flowering into autumn and winter.
