It’s Friday again so I continue the discussion (or better said monologue) about fruits versus seeds with Morina longifolia, commonly called Himalayan whorlflower.
If someone missed the Triosteum, see here.
What we call ‘seeds’ for Morina longifolia are also fruits (achenes). Morina is considered a warm germinator with the note that sometimes the hard teguments remain attached to the seedlings and are difficult to remove.
After being soaked in water for a few days, Morina achenes became soft and were easy to cut open. Actually, the tegument is quite thin compared to that of Triosteum, which is why I botched both seeds when trying to remove them (I couldn’t afford more fruits to test on).
But, we can have a look at the fully developed embryo I managed to extract from the second seed; notice the very large cotyledons.
Conclusion: soaking the seeds in water a few days (5-6), followed by sowing at room temperature should suffice for Morina. Before, I recommended keeping the seeds in a moist towel in the fridge for a couple of weeks, which is OK as well, but not really necessary.
