Description
The Thunbergia alata 'Sunny Suzy Rose Sensation' is a Black-eyed Susan with moderate growth that will charm with its flowers coloured from pink to black, delicately enhanced with fuchsia pink. Perennial in its country of origin, it is an adorable annual climbing plant in our climates, appreciated for its unique flowering that only ends with the first frost. Its stems covered with lush foliage cling to trellises on their own, allowing for the quick creation of large and decorative pots or astonishing hanging baskets that can be kept in the conservatory. It appreciates warmth and sun, fertile, cool, and well-drained soils.
The Thunbergia alata 'Sunny Suzy Rose Sensation' is a fast-growing, perennial, and voluble climbing plant that can only tolerate very light frosts. Its ancestor is native to the tropical regions of East Africa. It is grown as an annual in our climates. The cultivar 'Sunny Suzy Rose Sensation' 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 wrap around their support. They are covered with lush, dark green foliage composed of evergreen ( where frost-free) hairy leaves with toothed edges, shaped like a heart or an arrow. The flowering, which is rather early for a Black-eyed Susan, extends from June to October. The 3-4 cm (1-2in) flowers, enclosed in a hairy calyx, are borne on peduncles in the axils of the leaves. The corolla is tubular at the base and is followed by five flared lobes. The colour of the flowers, finely veined with pink, changes as they mature, ranging from true pink to almost white, with all shades simultaneously present on the plant. At the centre of this flower shines a beautiful eye, characteristic in a violet-black colour but bordered with intense pink in this 'Rose Sensation' variety. Its role is to attract pollinating insects.
The Sunny Suzy Rose Sensation Black-eyed Susan is suitable for both pot and open-ground cultivation, in sunny locations. A voluble climber, but lightweight, it pairs well with a perennial climbing plant like a herbaceous clematis and can also be used as ground cover. You can associate it with summer-flowering bulbs, such as gladioli: it will twist around the leaves and flower in the most unlikely places, adding whimsy to rigid flower beds. It will also make a great impact in a large hanging basket.
Note: Please be aware that our young plug plants are professional products reserved for experienced gardeners: upon receipt, transplant and store them under shelter (conservatory, greenhouse, cold frame etc.) at a temperature above 14°C (57.2°F) for a few weeks before being installed outdoors once the risk of frost has definitively passed.

Planting and care
You can plant your Thunbergia alata 'Sunny Suzy Rose Sensation' in open ground or in a pot. If you plant them in open ground, wait for the last frosts to pass (Black-eyed Susans cannot tolerate frost and do not cope well with temperatures below 8°). 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 or semi-shady position. They need a light and humus-rich soil and warmth. They tolerate short periods of drought quite well, but will need regular watering during hot summer weather to flower well. In pots, they need to be watered very regularly. Very floriferous and fast-growing, they reach 2m (7ft) in the space of one 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 period into autumn and winter.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
