About

Bornmuellera tymphaea is a flowering plant in the Brassicaceae that produces its blooms in spring, from April to June. It carries deciduous foliage on a well-branched habit and grows in full sun to partial shade. The species tolerates loam, sand or clay soils across acid to alkaline pH so long as they remain moist but well-drained. It is winter-hardy to H6 and suits cottage, informal and wildlife gardens.

In the garden

Bornmuellera tymphaea sits within the Brassicaceae and flowers in spring, reliably between April and June. The plant has deciduous leaves borne on a well-branched framework, offering a clear seasonal rhythm of leaf and bloom. Its compact habit fits into mixed spring schemes without dominating later in the year. Position the plant in full sun or partial shade; it tolerates north- to west-facing aspects and will perform in both exposed and sheltered sites. Soil type is flexible — loam, sand or clay are all acceptable — but ensure conditions remain moist yet free-draining and allow for acid, neutral or alkaline pH. In UK terms it is rated H6, very hardy, so it survives most outdoor winters without winter protection. Bornmuellera tymphaea works well in cottage and informal borders and is listed for wildlife gardens where a spring-flowering element is required. Grouping several plants provides a clearer spring display and integrates neatly with bulbs and other early perennials. Expect the main flowering window to be April to June, making it a dependable spring component in informal and wildlife-focused plantings.
