Description
Proboscidea louisianica is an herbaceous annual with the appearance of an orchid and a strong fragrance. Its claw-shaped fruit is what gave it its common name of devil's claw.
Proboscidea louisianica is a member of the Pedaliaceae family. It is native to the southern United States and Mexico. It is particularly found in Louisiana. The orchid-like flower consists of 5 fused and irregular petals forming a trumpet with undulating edges. It blooms from July to September. Both the calyx and leaves are hairy. The highly fragrant flowers measure 5cm (2in) in diameter and are white with pinkish-purple to violet spots. The throat is often speckled with purple.
The fruit is what draws the eye, and is the reason this plant has so many unique nicknames! The fruits form a double, strongly curved claw. When still green, they can be pickled and consumed. Once dried, they take on a characteristic hooked or claw-like appearance. These dehiscent capsules tend to cling to anything that brushes against them, dispersing their seeds far and wide.
The devil's claw is a highly branched spreading annual herbaceous plant. It reaches a height of 50 to 60cm (20 to 24in). It grows very rapidly under favourable conditions. Its foliage is rather heart-shaped and very hairy.
The devil's claw prefers sheltered locations that are warm and sunny. It thrives in light, organic-rich soils. It will look stunning in pots, or as a standalone plant to fully appreciate its flowering from July to September... and of course, its spectacular fruiting.

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.
