Thunbergia alata Tangerine
Black-eyed Susan
Delivered express, the package of mini root balls was "perfect"! After soaking, repotted into buckets, the 'Orange Susans' will wait indoors. I hope they'll have the same vigor as the yellow one that hasn't stopped flowering since last summer, cold or not! These mini root balls are truly a success!

Description
The Thunbergia alata, or more poetically Black-eyed Susan, is an annual climbing plant with charming orange flowers with a black heart.
With rapid growth, your young green plant will reach 2m in just one summer and will continuously flower until September.
It is suitable for pot cultivation as well as in open ground, in sunny locations. A voluble climbing plant but light, it pairs well with a perennial climber and can also be used as ground cover.
We often combine it with summer flowering bulbs, such as gladioli: it twines around the leaves and flowers in the most unexpected places, adding a touch of whimsy to somewhat rigid borders.
Young plants of 4 to 8cm in plug plants of 5 small plugs of 3.6 cm in diameter and 4 cm high. Our plants are at least eight weeks old and strong enough to be planted in open ground.
Note: Please note, our young plug plants are professional products intended for experienced gardeners: upon receipt, transplant and store them under cover (veranda, greenhouse, cold frame...) at a temperature above 14°C for a few weeks before planting them outdoors once the risk of frost has passed.

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).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
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 planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
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.
