Holmskioldia sanguinea aka Chinese Hatplant

Holmskioldia sanguinea is a shrub in the mint family, Lamiaceae. Its native range runs from the Himalaya to Myanmar. Kew places it in the seasonally dry tropical biome. It is not native to Britain or Ireland. Garden names include Chinese hat plant and mandarin's hat plant. The RHS also records the name cup and saucer plant. These names all refer to the same species in the supplied sources.

Chicago Botanic Garden describes its form as upright. It lists the species as a shrub, rather than a tree or climber. The supplied profiles give no mature height or spread. They therefore offer no firm guide to its space needs. They also give no details of its bark, stems, or leaves. Its upright form is a useful part of its garden profile. More precise claims about its shape would need further evidence.

The flowers come in red and orange shades. Chicago lists bloom periods covering September through December. This places its recorded display in the later months of the year. The source does not explain how bloom dates change with climate. Nor does it describe the flower parts behind the plant's common names. The supplied evidence gives no fruit or seed details. Its flower colour and late bloom period remain its clearest recorded display traits.

For light, Chicago lists both full sun and partial shade. This gives gardeners some choice when choosing a site. Its recorded USDA hardiness range is zones 10–11. The extracted care data call for moderate watering. Its native climate has a dry season, according to Kew. That fact alone does not establish drought tolerance in cultivation. The sources give no clear soil texture or pH preference. They also provide no UK hardiness rating.

Chicago recommends the species for use as a specimen plant. It also records visits or interest from birds and butterflies. This supports its value in gardens planned with wildlife in mind. It does not establish which animals pollinate the flowers. The supplied profiles name no pests or diseases. They offer no evidence about edible parts or medicinal use. They also give no toxicity assessment for people or pets. Those gaps should not be read as proof of safety.
