|The sea daffodil|
The sea daffodil is without doubt one of the most beautiful plants of the south-western Mediterranean. You can find it growing on the coastal sands or just above the high tide mark, and as its common name suggests, it is a genuine bulbous plant. However, despite appearances is not remotely related to the daffodil.

The Sea Daffodil will needs a hot summer in order to induce flowering and is often a shy bloomer in cooler climates. Again, growing in a pot will provide a warmer root environment and will also make it easier to move around should it need the encouragement of a month or two in a greenhouse.
It is hardy to USDA zone 8, and surprisingly will tolerate temperatures down to about −5 °C (23 °F). However I would rather not take that risk myself and instead overwinter in a frost-free greenhouse.
How to grow the Sea Daffodil from seed
|Sea daffodil seeds|
You can sow them into either pure grit-sand or a good quality, well-drained compost such as John Innes 'Seed and Cutting', with added horticultural grit, perlite or vermiculite for better drainage. If you can get it, mix in 30% volcanic grit and/or sand. Cover with a light dressing of compost and gently water. Place the seed in a bright position at between 15°C to maximum 22°C. Do not keep them any warmer as this can inhibit germination. Only water again once the compost has dried out.
They will not require a period of dormancy over the summer for the first 2 years but keep the seedlings more on the dry side. In the third year keep the young plants dry from June to mid-August.
Give them a half-diluted liquid feed once the leaves emerge and with a bit of luck your Sea Daffodil should flower in their third or fourth year.
