Where to plant sea holly

Eryngium / sea holly thrives in full sun and needs well-drained soil, so it’s happiest in dry gardens and sandy coastal areas. Plant in groups for a show-stopping garden display – sunny borders and carefully-positioned containers work well. Sea holly is extremely drought-tolerant once established, so you won’t need to remember to water your eryngium plants once they’ve settled in.

Where can I find advice on how to plant and grow hyacinths?

We’ve created a step-by-step Hyacinth Growing Guide that covers everything from planting depth and spacing to care tips for both garden and indoor displays. Perfect for beginners and experienced gardeners alike.

Which hyacinth varieties are the most fragrant?

All hyacinths offer a strong scent, but varieties like Woodstock , Delft Blue , and Pink Pearl are particularly well known for their rich, sweet fragrance.

Can hyacinths be grown indoors as well as outdoors?

Yes – many varieties are ideal for indoor forcing. Prepared hyacinths like Prepared Delft Blue or Prepared Jan Bos are specially treated to flower indoors in time for Christmas or early spring displays.

Do you sell mixed hyacinth bulb collections?

We do. Our mixed collections are great for bold, colourful spring displays and often include popular varieties in coordinated shades for maximum visual impact.

Are hyacinths suitable for containers and pots?

Absolutely. Hyacinths thrive in pots and containers. Choose top-sized bulbs and plant them close together for a dense, striking display. Just ensure good drainage and protect from extreme frost.

Are any hyacinths RHS Award winners?

Yes – many of our hyacinth bulbs carry the RHS Award of Garden Merit (AGM), which recognises varieties that perform reliably in UK gardens. Look for the AGM label on individual product pages.

What colours do hyacinths come in?

Hyacinths are available in a wide spectrum of colours including blue, pink, white, purple, yellow and red. Bestsellers include Woodstock (deep magenta), Carnegie (pure white), and Delft Blue (soft lavender-blue).

How long do hyacinths bloom for?

While bloom time can vary, most hyacinths flower for 2–3 weeks in spring. For longer-lasting impact, pair them with other spring bulbs like tulips or daffodils for layered flowering.

Can I naturalise hyacinths in my garden?

Some gardeners successfully naturalise hyacinths in borders or under deciduous trees, though they perform best with good drainage and partial sun. For longer-term naturalising, consider grape hyacinths ( Muscari ).

Are hyacinths safe for pets and children?

Hyacinth bulbs contain compounds that can be toxic if ingested, especially to pets. Always wear gloves when planting and keep bulbs out of reach of children and animals.
