I've actually tried growing samphire at home, and it's such a rewarding plant to have, especially if you love seafood dishes. Samphire, also known as sea asparagus, thrives in a salty, coastal environment. It’s happiest in sandy, well-drained soil, and surprisingly, it loves a bit of saline water—so you might want to add a bit of sea salt to your watering routine.
Starting samphire can be a little tricky because it prefers cooler temperatures to germinate. I easily got seeds from a reputable source and soaked them overnight before planting, which helped with germination. Keep them in a sunny spot; a windowsill or a sunny part of your garden would be perfect.
One tip is to mimic its natural environment as closely as possible, which means regular watering but ensuring the soil doesn't get waterlogged. As for harvesting, you can snip off the tips when they're about 6” tall; that usually gives the best flavor. It’s pretty straightforward once it gets going!
Have you considered where you’ll plant it or how much you’d like to grow? I found a small patch was more than enough for personal use.
