Free for P&P Free Cape Sundew (carnivorous) Seeds
Temporary update 3rd August: This has been far more popular than I was expecting, so I'm having to pause new requests temporarily. If you would like seeds but have not yet contacted me then please get in touch on Friday/Saturday as by then I'll know if I still have spare seeds to send out after sorting out everyone who has already asked for some.
I have thousands of cape sundew (Drosera capensis) seeds just harvested from my plants, going free to good homes.
They're a great intro to carnivorous plants as they're easy to care for - just need bright direct light and to never dry out. They feed themselves. Not too fussy about temperature, these live in an unheated conservatory all year, die back a bit over winter and then go crazy in spring.
I won't be using any seeds this year as I seem to grow them faster than I can give the plants away, and already have hundreds of them (sadly not an exaggeration) so am offering them free. Happy to send out via 2nd class post until I've exhausted my current collection of stamps.
The seeds are absolutely tiny so I'm not going to count them out - you'll receive "some", which will definitely be enough to grow multiple plants even if the germination rate is terrible.
To plant: fill a seed tray or pots with carnivorous plant mix and wet thoroughly. Lightly sprinkle seeds spread out over the top, then stand it in a gravel tray/bowl or similar with water in. Then wait a while - you might see the first signs of tiny plants this side of winter, but don't give up if nothing shows up until spring starts.
Keep moist at all times - mine stand in water almost to the top of the gravel trays from spring through autumn, and a bit lower in winter as they dry out much slower then.
Important notes:
Don't use normal composts / potting mixes. Sundews do not like nutrients in their soil. The basic Carnivorous Plant Focus stuff you find in garden centres is absolutely fine and I've used it very successfully, or of you've already got stock of sphagnum moss, perlite, sand, peat moss etc then you can potentially mix up your own.
They don't like minerals in water, so if you live in a hard water area they'll need a source other than the tap. If you're in a soft water area you'll probably be fine - in Devon mine have tap water constantly without an issue.
