- - - -
Asphodeline lutea, commonly known as king's spear, yellow asphodel, is a drought tolerant perennial that is well suited for Mediterranean plantings.
Asphodeline lutea was already described and the name validly published by Carl Linnaeus. It was Heinrich Gottlieb Ludwig Reichenbach, however, who reclassified it into todays valid botanical systematics in 1830.
The perennials have a stemless growth and reach heights of 80 to 150 centimetres. The plants reach a width of 30 to 50 centimetres.
Asphodeline lutea is deciduous. The fern-green, simple leaves are alternate. They are linear and clasping with entire margins and parallel venation. The leaves are around 60 to 80 centimetres large.
Flowers and Fruits
Asphodeline lutea produces racemes of erect, yellow six-stellate flowers from May to June.
The perennials produce ornamental brown loculicidal capsules from summer to autumn.
Asphodeline lutea is native to the Mediterranean.
The perennials prefer a sunny situation on dry soil. The substrate should be sandy-loamy, gritty-loamy, sandy clay, loamy clay or peaty soil with a pH between 8 and 10. They tolerate temperatures down to -18Â°C (USDA zone 7).
Classification after Prof. Dr. Sieber:
- flower beds (rich soil)
- open areas
Tolerance of special soil conditions
- none: waterlogging, winter dampness
Asphodeline lutea is considered a very valuable wild perennial. The recommended planting distance is 40 centimetres, the perennials are best planted in groups of 3 to 5. Suited for rockeries and for beds and borders, as well as suited as slope plant, specimen plant and as bee pasture.
