Of course, it could be more important in the long-term to base it on what the NON-members want, given that most of us existing members are OAPs.

Re: Daubenya

Just to terminate the diversion, I guess the flowers on my Tropaeoleum are 2cm long if you include the spurs, so not that small. It's also a young plant. The leaves have died off as the plant was left dry for the last 3 weeks while I was on holiday. Anyway, getting back on topic, as for Daubenyas - ...

Re: Ceraria pygmaea with ODD growth

I'd go with the graft theory too. I don't know why all the Ceraria namaquensis plants one sees are grafted - it seems do do just fine on its own roots, and is not particularly slow. It's a bit more surprising that people would graft C. pygmaea as I would not have thought it would develop a caudex if...

Tropaeolum tricolor has got quite showy flowers, several cm long. Have you checked out your plant Ralph?
Hi Terry
the flowers on mine can't be much above 1cm long (the coloured bit, not counting stalks).
Perhaps it's rather variable. Or maybe there are other similar species?

Re: Daubenya

Nice. I'm enjoying some Lachenalias right now; before that it was Massonias. I've also got Tropaeolum tricolor flwoering - very jolly, but tiny flowers.

Re: Watering

I water the Madagascan ones in winter as that is when they seem to flower (I water them in summer too).

Re: Growing dioscorea elephantipes from seed

Give the seedlings plenty of root room, and keep potting them on into bigger pots frequently - and give them plenty of water (when in leaf). They will develop a big caudex much more quickly that way.

Re: Own soil mix for Cacti and Succulents

In my experience, sand particles are too fine, with too much surface area, which water adheres to by surface tension, keeping the compost too wet. I use coarse grit, not sand.

Re: Tylecodon bucholzianus aerial roots?

This can happen when the roots have rotted off, but the stems are sound. The plant is essentially treating itself as a cutting.
