I've planted Mesembryanthemum Crstallinum (ice plant, salt herb) from seed. When they started sprouting, the plants turned out to resemble my midday flowers (Mesembryanthemum spp., according to THAT seed packet) a whole lot.
Does anyone know whether the midday flowers are edible, too? The midday flower leaves are a little smaller, otherwise, there's NO difference - and I've actually found that midday flower is one of the names for the common ice plant...
