Last Autumn I collected the seeds from my crocosmia and have germinated lots. Will they come true and, if so, how long will it take?
Development will probably be fairly rapid but other seedlings I have seen, while of similar structure to the parent, were not red.
We saw the same thing as Ron writes when we grew some seedlings from seed also in that the offspring can be more of an orange in color than the parent plants were being more of a scarlet red. We grew and sold our seedlings as assorted Crocosmia, not as Croscosmia 'Lucifer'. The more true method of propagation is from separating the bulblets from the clumps of bulbs and even then there may be some slight color variance shown in some of the offspring. Is it worth persisting? Yes, it is. You may even select out a darker or a richer red than the parents are as we were able to do. Jim
