Are you looking for anything in particular? I would be interested and these are the things that I would (or might-have to double check) be able to offer:
Haemanthus albiflos
Crinodonna Lily pink
Scadoxus multiflorus-not sure about this one
Neomarica gracilis
Thunbergia battiscombei (tuber)
Asarina purpusii (tuber)
Dahlia coccinea 'Orange Hybrids' tubers
Please let me know if any of these things interest you. There may be others. I'll check.
Thanks.
