Hello Jonathan Mitchell et al.

My experience and the experience of others who are doing research on
the germination of "fynbos" species (Roridula spp. are plants from the
fynbos regions of the southern and western Cape) is that they respond
to treatment with "smoke water" - a smoke solution in water produced
by the burning of various organic residues (fynbos species and grasses
such as Themeda triandra, etc.).

The Kirstenbosch botanic gardens produce a product called "Instant
Smoke Plus Seed Primer" which is filter-paper circles saturated with a
smoke solution and then dried. One circle soaked in 50ml water and
the seeds soaked in the resultant solution for 24h does the trick.
This treatment works for many plants including proteas, ericas,
Anigozanthus, Leschenaultia, grasses, etc.

I would certainly consider this as a treatment for many carnivorous
plants and Roridula spp. as well.

Instant Smoke Plus can be obtained from:

D.Orriel - Seed Exporters, 45 Frape Avenue, Mt.Yokine, Perth, Western
Australia 6060.
