Silene uniflora (Sea Campion) [15 Seeds]


Germination Information: Based on my own experience starting these seeds, I recommend them only for gardeners who are used to handling seeds that benefit from a natural or artificial chilling period.

Surface-sow the seeds (pressed into the moist growing medium) in fall to mid winter and leave the pot outdoors. If you sow after January, you could try giving the seeds an artificial chilling period of about a month. I have read that these seeds can germinate if started directly in warm, bright conditions, but I didn’t have luck with that, though I didn’t give them much of a chance, to be fair: I sowed indoors on April 1, then set the pot outside on April 9 since no seedlings had appeared; sprouts finally started to pop up on April 25.

A few years ago, I purchased and sowed seed of Silene laciniata, a southwestern species with red flowers. Once I saw the mats of blue-green foliage, though, and then the bright white summer flowers—each with a puffed-up, veined calyx—I figured out that I had received sea campion (Silene uniflora) instead. I didn’t mind too much, though, because I have really enjoyed growing it. The clumps reach just a few inches tall in leaf and are covered with blooms (to about 6 inches tall) through the first summer. They aren’t too pleased with heavy, winter-wet soil—they much prefer loose, well-drained soil—but they might survive even that to flower again the following year. Apparently the plants tend to be short-lived even in ideal conditions but will self-sow. The straight species isn’t often seen in gardens, so if you have a sunny, well-drained spot along a path, on top of a wall, in paving cracks, or in a rock-garden setting and would like to grow something a bit different, sea campion is worth a try. Full sun. Perennial; Zones 3 to 7.

Collected starting in late July 2022. At least 15 seeds.
