Datura ‘Golden Queen’ is a much sort after form of the annual Datura, with magnificent double, lemon-yellow flowers that are exquisitely whorled and twisted.
Beginning in early summer and continuing until the autumn weather sets in, the plant is covered with immense 15 to 20cm (6 to 8in), upward facing ruffled blooms which are so fragrant that a single plant perfumes the garden.

Normally treated as a half-hardy annual, it will flower the first year from seed and is earlier than most other varieties. The plant is quite compact in containers. It will flower in a 20cm (8in) pot and reach about 24 to 48cm (1 to 2ft) high. In the garden, it forms a dense, well-branched shrub to 1 to 1.5m (3 to 5ft) tall. The flowers are followed by highly ornamental fruits, remaining decorative for long periods.

Datura love sun and heat, although not a fussy plant, prefers moist, well-drained soils. Hardy to 4°C (40°F), and although easy from seed can also be over-wintered in a greenhouse environment.

Sowing: Sow in spring at 22 to 26°C (70-85°F)
Sow seeds in a well drained compost, “just cover” with 2mm (1/8th in) of soil or vermiculite. Do not exclude light, as the seeds need light to germinate. Stand pots in water to soak thoroughly. Cover pots or tray with a plastic lid or seal inside a plastic bag. Seeds may take anything from 7 to 40 days to germinate.
Prick out each seedling as it becomes large enough to handle, transplant into 7.5cm (3in) pots or trays.
They will grow fast if you keep transplanting them up to larger pots and don't let them get root-bound.
Gradually acclimatise to outdoor conditions for 10 to 15 days before planting out, space 60cm (24in) apart.

Cultivation:
Grow outdoors in full sun in frost-free area in moist but well-drained soil. Water freely especially in periods of drought. These require pretty much full sun to bloom and do well. - If they are planted in the shade they will have few blooms. Partial sun is acceptable but they will be more 'leggy'.
They will bloom in pots if you keep them in the sun and keep moving them up to larger pots as needed.
Fertilise monthly and remove seedpods regularly to encourage further blooms.
Datura is technically a short lived perennial which means that it can be overwintered in frost free conditions. Cut the plant back to the base before first frosts and keep in a warm sheltered position.

Plant Uses:
Architectural, City/Courtyard Gardens, Patio/Container Plants or Sub-tropical, Conservatory, Greenhouse.

NOTE:
All parts of plant are poisonous if ingested.

The recent popularity of the Datura has sparked debate about the differences between them and the Brugmansia. Datura are all annuals or short-lived perennials with no woody growth. Their round, spiny seedpods burst open when ripe, and their blooms face upwards. Brugmansia, grow into woody perennial shrubs or trees in tropical climes. Their blooms dangle downwards, and their longer, narrower, smooth seedpods must be broken open.
An interesting way of remembering the difference between the Datura and Brugmansia Trumpets;-

“Devil's Trumpet look up at heaven, while
Angel's Trumpet look down towards hell!”
