Calceolaria thyrsiflora

Calceolaria thyrsiflora is a small woody plant from central Chile. It belongs to the family Calceolariaceae. Kew lists its growth form as a subshrub. Plants For A Future describes it as a shrub. These accounts place it among the smaller woody garden plants. Its recorded height is about 2.3 feet [0.7 metres]. The supplied sources give no mature spread. Kew places the species in a subtropical climate. The RHS confirms that it is not native to Britain or Ireland.

The species account gives few details about its appearance. It does not describe the bark, stems or leaves. Nor does it give flower colour, shape or bloom dates. The flowers have both male and female organs. This does not establish how the plant receives pollen. No fruit or seed description appears in the supplied evidence. The RHS includes a broader account of the genus. That account does not establish these traits for this species.

Plants For A Future lists sun and partial shade as suitable. It accepts sandy, loamy and clay soils. Its stated pH range runs from mildly acid to mildly alkaline. The plant prefers moist soil, but its needs change with the season. It needs ample moisture during summer and dry conditions during winter. A single year-round watering rule would miss this distinction. The source lists USDA hardiness zones 8–11. It also limits outdoor growing in Britain to the mildest areas. Its separate reference to UK zone 9 is not an RHS H rating.

Cultivated beds are the garden setting named in the evidence. The small stated height provides some guide to its scale. Its missing spread makes planting distances harder to judge from these sources. Plants For A Future gives two ways to raise more plants. Sow seed in a greenhouse in spring, or divide plants then. The evidence gives no growth rate or pruning guidance. It also names no pests or diseases affecting this species.

Plants For A Future records no known food uses. It gives the plant an edibility score of zero. It reports traditional use for sore throats and mouth complaints. Those reports do not establish treatment safety or effectiveness. The source lists no known hazards, but this does not prove safety. It records no other uses and flags no weed potential.
