The plants you grow from won't technically be 'Golden Fleece'. You'd have to grow if from cuttings to end up with plants you could truly call 'Golden Fleece'.
The plants are fertile, however, and many of the seedlings are likely to be very similar to the parent plant, so you may be able to get the sort of plants you want by growing them from seed. The seed will need to be cold stratified for good germination. The seedlings should bloom the first year if they are grown well.
