Description
The Thunbergia alata 'Sunny Suzy Brownie' is a variety of Black-eyed Susan that stands out for its more modest growth and especially for the almost brown colour of its flowers, against a burnt orange background. They open, like all 'Susans', around an almost black centre that earned them this lovely nickname. Invasive perennial in its country of origin, it is an adorable annual climbing plant in our climates, appreciated for its original 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 stunning hanging baskets that can be kept in the veranda. It appreciates heat and sun, fertile, fresh, and well-drained soil.
The Thunbergia alata 'Sunny Suzy Brownie' is a fast-growing, perennial, and voluble climbing plant that only tolerates 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 Brownie' reaches an average height of 1.60m (5ft) in just a few months. Its stems wrap around their support. They are covered with lush, dark green foliage, composed of evergreen (where it is frost-free) leaves, villous, with toothed edges, in the shape of a heart or an arrow. The flowering, rather early for a Black-eyed Susan, extends from June to October. The 3-4cm (1-2in) flowers, enclosed in a villous calyx, are borne on a peduncle in the axil of the leaves. The corolla is tubular at the base and extends into five flared lobes. The color of the flowers changes with the hours, sunlight, and temperature: starting orange, they gradually darken until they become almost brown. In the center of this flower shines a beautiful eye, with a characteristic violet-black color, whose role is to attract pollinating insects.
The Sunny Suzy Brownie 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 bloom in the most unlikely places, adding whimsy to rigid flower beds. It will also make a big 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 in a sheltered place (veranda, greenhouse, cold frame...) 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 Thunbergia alata 'Sunny Suzy Brownie' in the ground or in a pot. If you plant them in the ground, wait until the last frosts have passed (They cannot tolerate frost and don't do well in 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 warm, sunny, or partially shaded location. They need a light and humus-rich soil, as well as warmth. They tolerate short periods of drought quite well, but will need regular watering during hot summer temperatures to flower well. In pots, they should be watered very regularly. Very floriferous and with rapid growth, they reach 2 m 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.

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.
