Cali,
Ptilotus are fairly easy to grow from seed. In their native habit they grow after autumn rains and then die off before the onslaught of summer. if you haven't assigned your spent plant to the compost heap, collect the seed and scatter it about.. autumn rains should reward you with germination. I'll take Oron's word on the cultivar name but it doesn't look significantly different from the wild plants to me, so your seedlings should be somewhat similar. Cheers Anita
