Helichrysum umbraculigerum

Helichrysum umbraculigerum Less.

Common names: woolly umbrella helichrysum (Eng.); kerriekruie (Afr.)

Introduction

Helichrysum umbraculigerum was a relatively new addition to the herbaceous borders in Kirstenbosch in 2004. With its sulphur-yellow flowers and naturally long stems, it is a plant with great potential for most gardens.

Description

Description

Helichrysum umbraculigerum is a fast-growing, erect, perennial herb, reaching a height of ± 1 m and a spread of ± 1 m. It becomes woody with age. The leaf shape is extremely variable depending on its geographical distribution. According to Hilliard (1977) there are five very different leaf forms of this plant. The form growingin Kirstenbosch has ovate, untoothed leaves, 20-80 x 3-25 mm, witha long petiole (leaf stalk). The leaves are green above and slightly silvery and woolly on the underside. They become smaller upwards on the cobwebby, grey stems.

The flowers resemble large, flat, yellow umbrellas with a white woolly underside. They are irregular in shape and vary from 30-100 mm in diameter. Flowering time is in late summer, from late January to April. Flower heads become golden in colour as they age, remaining handsome for many weeks.

Distribution and habitat

Distribution description

The wide range of this plant stretches from the Eastern Highlands of Zimbabwe to the highlands of the Eastern Cape. It occurs in grasslands, forest edges and streambanks. The natural distribution implies a frost tolerant, summer rainfall plant.

Derivation of name and historical aspects

History

The genus name Helichrysum comes from the Greek (h)elios, meaning sun and chrysos, meaning gold; the Latin word umbraculigerum means, bearing woolly umbrellas.

The genus Helichrysum has 244 species in southern Africa with many noteworthy horticultural species. Mention ‘everlasting’ and most South Africans can immediately put a plant to mind! Several species, such as H.splendidum, H. populifolium and H. argryophylum have found their way into gardens.

From the common Afrikaans name kerriekruie (meaning curry herb) it can be speculated that Helichrysum umbraculigerum has been used for culinary or medicinal purposes. Many other helichrysums such as H. nudifolium are used for their wound-healing and antifungal properties.

Horticulturally, this plant has uses as an excellent filler in herbaceous beds, flowering at a time when little else is colourful and as a cutflower it lasts for over two weeks in the vase.

Growing Helichrysum umbraculigerum

This plant naturally occurs in the summer rainfall areas of southern Africa, but can be successfully grown elsewhere, with moderate watering in summer. Planted en masse it produces a wonderful display of colour. It can also be used in herbaceous borders as a background filler. It is an excellent cutflower, producing up to 50 long stems per adult plant.

Helichrysum umbraculigerum must be grown in full sun or dappled shade. It requires a well-drained, loamy soil with added compost. In the winter rainfall areas, a good watering every 4 to5 in days in summer is sufficient.

Easily propagated from tip and stem cuttings, H. umbraculigerum is fast growing and will flower in its first summer. By year three it produces many long flower stalks. Cut back heavily in winter to prevent the plant from becoming too woody.

Helichrysum umbraculigerum seeds

Hardy Annual, Strawflower, or Everlasting, is an easy plant to grow, with a wide range of colors. The true petals are found in the center of each flower and they are surrounded by colorful, straw-like bracts. The flowers bloom from summer to early autumn. Harvest flowers for drying before they open fully and hang them upside down in cool, dark place. Seeds need light to germinate; plant in porous soil. They prosper during hot summers, but high humidity or continual damp may cause stem rot.
Tips:
When seedlings are large enough to handle, transplant and grow on in cooler conditions. Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost 30cm (12in) apart in sun and ordinary well drained soil.
Harvesting:
Pick when foliage is quite dry and the flowers are well open, tie in small bunches and hang upside down in a dry, well ventilated place until dry.
