Ilex purpurea Seeds | Red Holly

Red Holly (Ilex purpurea) with glossy toothed evergreen leaves and dense clusters of bright red berries — Red Holly (*Ilex purpurea*): Aquifoliaceae, the berry-loaded holly behind the Chinese medicine si ji qing.

LATIN NAME: Ilex purpurea

COMMON NAME: Red Holly

Plant Profile

The Red Holly is an evergreen tree of the holly family from the warm hills of eastern and southern China, growing to about ten metres with a dense, rounded crown of glossy, narrowly toothed leaves. In spring the small, whitish flowers open in the leaf axils, and on female trees they are followed by the display the name records: dense clusters of small, bright red berries that load the branches in autumn and hold through the winter, feeding a procession of thrushes and bulbuls.

It is the holly of the Chinese winter garden, and it is also a medicine tree: the dried leaves are the herb si ji qing, evergreen, a preparation with a long record in southern Chinese clinical tradition. Male and female flowers are borne on separate plants, so a berry display requires both.

Science & Biotechnology

Its taxonomic position has a footnote that matters: most current treatments merge this species into Ilex chinensis, treating the name purpurea as its synonym, and the garden trade has carried both labels for decades. The medicinal record is the more substantial science: the leaves, known in the pharmacopoeia as si ji qing, have been studied for their phenolic-acid content and for topical and oral preparations used in southern Chinese hospitals, particularly in wound-care and anti-inflammatory applications, with published clinical and laboratory work behind a tradition that long predates it. Like all hollies, the berries are mildly to moderately toxic and are bird food, not human food.

The genus Ilex as a whole is chemically rich, and its caffeinated teas, from yerba mate to the bitter ku ding cha, come from different species than this berry tree.

Uses & Benefits

In the garden it is the winter berry tree of the Chinese style: a dense, glossy evergreen that carries red fruit through the cold months and provides the berry display that European hollies give in colder climates. Birds strip the crop progressively through winter, and the evergreen crown gives year-round cover.

Its medicinal use, si ji qing, belongs with qualified practitioners and the hospital tradition that studies it; the berries belong to the birds. For the gardener, the pairing of one male tree among several females is the whole secret of the display.

Growing from Seed

Holly seed wants a long, double dormancy: clean the pulp from ripe berries and sow into a moist, humus-rich compost, then leave the pots outdoors for eighteen months, or warm-stratify for three months and cold-stratify for three before sowing and expect germination the following spring. Keep the trays shaded and just moist throughout.

Grow the seedlings in part shade for two seasons, pot on deep, and plant out into moist, well-drained soil in sun or part shade, setting one male among the females and spacing for a ten-metre crown. Mulch annually and water in dry summers until the roots are down; after that the tree manages itself.

Our Take

The red-berry holly of the Chinese winter garden, and the source tree of the herb si ji qing. Plant a male among the females and the winter display is guaranteed.
