I harvested another batch of sundew seeds from my few pots of Sundews ( Drosera burmannii) Now with better photographing equipment, I am able to show you how the seeds will look like:
They are black elongated seeds with tapered ends, usually 20-40 seeds are developed in a seed pod. Unripe seeds are pale green in colour and not viable to germinate. However, seeds that are ripe have a long lifespan, I have germinated seeds which I harvest a year ago! Sundew seeds can stay viable for around 2 years, and of course chances of germination will be lower than those freshly harvested.
They are extremely small, a gust of strong wind or brushing the seed pods will send the seeds away, which is their way of propagation. They will take 2-4 weeks to germinate and you can expect them to be almost microscopic for the first leaves! In fact, they look like tiny green specks in the pot!
Seeds of this size make sowing fairly difficult. Unlike other seeds, we can organise and space them equally in the pot. However for sundew seeds, they are just too small for our fingers to space them out neatly. I can only arrange them properly when they had germinated and had a few leaves, which I use a tweezer to move them around before their roots had established into the media. It is no easy feat at all! You may just squished them into pulp if you applied too much pressure!
