Pincushions, Leucospermum

Pincushions, belonging to the genus Leucospermum, are notable for their diverse growing habits and striking floral displays. These plants can range from upright shrubs to small trees, typically reaching heights of 1–5 meters, and sometimes exhibit prostrate growth, forming low mats. They are characterized by their alternately set, mostly hairless leaves, which can vary in shape from linear to spade-shaped. The leaves' edges may be entire or toothed towards the tip​​.

Leucospermum flowers are a highlight, displaying a variety of colors including yellow, orange, crimson, pink, or white. The flowers, subtended by bracts, form heads that are seated or stalked and can either appear singly or in clusters. These floral heads, resembling pincushions, contribute to the plant's common name. The individual flowers have a perianth tube that can be straight or curved, with lobes that may roll back or stick together, and brightly colored styles that extend prominently, adding to the pincushion effect​​.

Leucospermum is not a succulent, but an evergreen shrub in the Proteaceae family, native to South Africa and Zimbabwe. Its globe-shaped, pincushion-type flowers are primarily in shades of red and yellow. These plants are celebrated for their long flowering period, evergreen foliage, and attractive large flower heads, making them popular both as garden ornamentals and cut flowers. However, it's worth noting that many Leucospermum species have very limited ecological ranges and are considered rare or endangered​​​​.

Caring for Leucospermum involves ensuring well-drained soil and full sun exposure. They require regular watering, especially during the first two years of growth and in sandy soils or potted conditions. While Leucospermum is adaptable to various soil types, they thrive in well-drained, slightly acidic soil and can even be grown in pots with the right potting mix. These plants are deer resistant and attract birds and bees with their nectar-rich blooms, making them suitable for Mediterranean gardens and xeriscaping​​.
