Bupleurum rotundifolium 'Griffithii' Hare's Ear / Thorow-Wax 'Griffithii'
Zesty lime-green starburst flower heads above oval blue-grey leaves that wrap around the wiry stem — Bupleurum 'Griffithii' is the cottage garden's secret weapon for any bouquet that needs lifting, brightening or making to look more expensive than it actually is.
If you have ever envied the bright lime-green Euphorbia stems that florists work into expensive arrangements, Bupleurum 'Griffithii' delivers the same effect for a fraction of the price and without the irritating sap. The lime-green flowerheads are technically umbels (it is a member of the Apiaceae family, like Ammi and fennel), surrounded by showy bracts that hold their colour exceptionally well both fresh and dried. The stem and leaf form is genuinely architectural — pierced rounded leaves that wrap right around the stems. As a cut flower, Bupleurum is one of the most useful "lifters" any bouquet can include: it brightens dark colours, complements warm tones, and adds a sophisticated, almost-glowing quality to any arrangement. Hardy annual that grows to 60–90cm.
A note on growing
Crucial growing note: Bupleurum is one of the very few seeds that needs darkness to germinate. If you surface-sow as you would for most flower seeds, they will simply refuse to germinate. Sow directly outdoors from September (for overwintering) or March to April. Cover the seeds completely with soil or vermiculite to exclude light. Bupleurum prefers cool temperatures to germinate (13–15°C) — do not put them in a hot propagator. Germination takes 14–21 days. Full sun, well-drained soil. The plant resents transplanting due to its taproot, so direct sowing produces the strongest plants. Stems are wiry but can become top-heavy in full bloom; planting close together (20cm apart) lets the plants support each other.
Where it shines
In the cutting garden as a primary "lifter" — the lime-green is the colour every florist wants more of, and Bupleurum delivers it in abundance with exceptional vase life. As a dried flower, the bracts hold their colour for years if kept out of direct sunlight (UV light is the enemy of green dried flowers). In the cottage border, the unusual stem-and-leaf form provides genuine textural interest among more conventional shapes. We grow Bupleurum specifically for our dried flower range here in Norfolk — it is one of the most reliable and most useful varieties in the everlasting cutting garden.
Plant alongside
The classic florist combination: Bupleurum with hot pink (Geum 'Mrs Bradshaw' or Achillea 'Cerise Queen') for high-energy contrast, with deep crimson (Amaranthus 'Love-Lies-Bleeding') for sophisticated drama, or with white (Ammi majus or Cosmos 'Purity') for a cool, cool-toned bouquet. Also outstanding alongside Bells of Ireland for a green-on-green architectural cutting scheme.

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.
