Caulophyllum thalictroides (L.) Michx.
Caulophyllum thalictroides is a perennial.
Caulophyllum thalictroides was already described and the name validly published by Carl Linnaeus. It was AndrÃ© Michaux, however, who reclassified it into todays valid botanical systematics in 1803.
The perennials reach heights of 60 to 75 centimetres, the main growing season is in spring and summer. They have a erect habit.
Caulophyllum thalictroides is deciduous. The dark-green, ternate leaves are alternate. The leaflets are ovate. The foliage is porous.
Flowers and Fruits
Caulophyllum thalictroides produces cymes of light-green six-stellate flowers in May.
From spring to summer the perennials carry only few ornamental, edible brown fruits.
Caulophyllum thalictroides is native to eastern Canada, the Northeast of the US, the central Northeast of the US and the Southeast of the US.
The perennials prefer a half-shady to shady situation on moist soil. The substrate should be comparatively rich with a pH between 4,5 and 7. The plants need a soil depth of at least 41 centimetres for good growth. They tolerate temperatures down to -18Â°C (USDA zone 7) and need a frost-free period of at least 17 weeks.
Tolerance of special soil conditions
- none: soil salinity
- low: anaerobic soil, drought, calcareous soil
The recommended planting distance is 30 to 40 centimetres, the perennials are best planted in groups of 3 to 5.
