Phil, the "kaka beak" (it's botanical name is Clianthus puniceus) is a close
relative of the Sturt Desert Pea. It would appear that it is easier to grow
judging by the cultivation details given in a book I have. 10" pots are
recommended for it - hope my SDPs don't mind 4" ones... I'm afraid that I
don't know of any seed suppliers. but I occassionally seen what I assume are
kaka beaks being sold as SDPs - as you say, the lack of a "black" centre
gives them away (my last SDP's black centre actually appears to be a very dark
red/maroon sort of colour - I think...).
