Thanks again, Lorn. I'll have to see what the results of my attempts this year are and then try mixed pollens if needed next year. I assume you pick something that looks drastically different to your desired pollen 'A' so you can tell which is the parent in any offspring?
In other news, 'Soft Whisper', another Tonkin hybrid, has unexpectedly beaten 'Rascal' to opening. Found it another one difficult to photograph, as the colour perceived by the camera varied depending on lighting and angle.
'Pearl Jennifer' from Tesselaar has been open for a week now (and being used for hybridising), whilst the other from Van Diemen Quality Bulbs (received as a substitute for 'Sweet Surrender' and planted about a fortnight later) has started to open a couple of days ago.

Finally, 'Sweet Surrender' (sourced from Golden Ray Gardens) opened today. The plant is quite small and the blooms are as well - a rather mediocre result (there is one other that will bloom and it has a single bud on it - hopefully it will look nicer and more photogenic). From photos I've seen this should improve next year. It had previously been leaning a lot, so I had recently staked it (hence the odd arrangement of the buds).
