Hesperis matronalis 'White' Sweet Rocket / Dame's Violet 'White'
Tall luminous white spikes that release a heady fragrance of violets and cloves after dark — Hesperis 'White' is the moon-garden hero that fills the tricky gap between spring tulips and summer roses, providing pure-white evening-scented flowers in shaded borders where few other plants will perform.
While the classic Sweet Rocket is violet-purple, the white form brings crisp, sophisticated elegance to the cottage evening garden. The tall 75–90cm branching stems carry the same loose clusters of four-petalled flowers, but in pure luminous white that genuinely glows in low evening light. This is the variety for moon gardens — plant a drift beneath a north-facing tree or alongside a white-painted garden seat, and the pale flowers will appear to glow at dusk just as their fragrance releases. The scent itself is identical to the purple form — powerful sweet violets-and-cloves designed to attract night-flying moths. Hardy biennial (H7). RHS Plants for Pollinators recognised. Orange Tip butterfly larval food plant — the white form is equally valuable to the butterfly as the purple. Bees, hoverflies and small pollinators visit during the day; moths visit at dusk.
A note on growing
Sow direct outdoors May–July, or in modules indoors at 15–18°C. Cover lightly with 3–5mm fine soil. Germination 14–21 days. Move plants to their final positions in October — partial shade or sun in moist humus-rich soil. As with all Sweet Rocket varieties, partial shade with consistent soil moisture is the most reliable position.
Self-seeding: white Hesperis self-seeds reliably, though offspring can revert to the purple form over time as Hesperis colours are genetically variable. To maintain pure-white colonies, rogue out any purple-flowered seedlings before they set seed — this maintains genetic purity over generations.
About Cabbage White caterpillars: same Brassica family connection as the purple form — check for caterpillars from July onwards.
Cutting tip: same as for the purple — cut when one-quarter of florets are open; the stem continues to open in the vase.
Where it shines
In moon gardens and white borders, where the luminous pure-white flowers glow in evening light just as the fragrance releases — combining visual and olfactory dusk magic. In shaded woodland borders. As an essential "moon garden bridge" — Hesperis 'White' fills the tricky gap between spring tulips ending and summer roses beginning, providing white flowers in May, June and July when many other moon-garden whites are absent. As cut flowers for white-themed romantic arrangements. In wildlife gardens for Orange Tip butterfly support.
Plant alongside
The classical moon-garden combination: pair 'White' Hesperis with Cosmos 'Purity', Ammi majus, Foxglove 'Alba White', and Cornflower 'Snowman' for a layered all-white cottage cutting garden that genuinely glows at dusk. For colour contrast, combine 'White' with 'Purple' for the timeless purple-and-white Sweet Rocket pairing. With Honesty (Lunaria, related Brassica) for the classic biennial woodland partnership.

Be a smarter gardener
Gardening organically is a more affordable and long term alternative to using chemical fertilisers. Natural Grower products eliminate waste because the nutrients are slowly released to the plants as they need them. Over the long-term you save money because your soil health naturally improves, which in turn produces healthier, stronger, disease resistant plants. Chemical products may cost less financially in the short term, but they don’t provide any long-term benefits and the damage they do to the natural eco-system in the soil is costly.
Slow release for sustained growth
Organic fertilisers are broken down slowly by organisms in the soil to produce a more measured, consistent, natural release of nutrients. This results in uniform growth with strong stems and leaves, unlike chemical fertilisers which provide a sudden boost resulting in tall lanky plants. Stronger plants are more resistant to disease, and with the presence of mycorrizhal fungi to strengthen the roots, the plants, soil and fungi all work together long-term to create the perfect natural eco-system.
Love your land
The organic matter in Natural Grower will help keep your soil or compost in optimum condition, retain moisture over the dry summer months and improve the health and structure of your soil. The presence of natural Mycorrhizal fungi in our products enhances root growth, enabling plants to extract nutrients and absorb water more efficiently from the soil or compost. By using our products you will be supporting and enhancing the natural eco-system in the soil.
Embrace sustainability
Natural Grower’s chemical free fertiliser products are approved organic, biodynamic and vegan. Plant-based and free from chemicals they are safe to use around wildlife, pets and children. Eco-friendly and sustainably produced in the UK. Our packaging is made from recycled plastic where possible and is all 100% recyclable. We are always happy to refill used containers, and often sell our products in reused containers or slightly damaged packaging at a reduced price. Reduce, reuse, recycle.
