If you grew hybrid bulbs for coloured flowers then the seed may not come 'true' from seed. You could end up with cream flowers, perhaps with mauve on the outside of the petals. You might also be lucky enough to get the scent back - and that would be worth the wait. One way you could check viability is to place some seed on a damp tissue or paper towel, cover with the paper folded over and put the whole lot into a snap-lock baggie in a warm place to see if the seeds begin to shoot. If they do then you could lightly sow more seed into containers with regular seed raising mix, damp but not wet. I suspect they may need to be covered but not deeply. The ones that sprouted on the paper can be picked up with tweezers and put onto seed raising mix to continue. However, they might not show until the usual months for the leaves to start appearing - and that's over winter. If your original raising container has enough depth, you could leave the seedlings there for at least a year to grow on and develop a bulb you can then pot up to grow to flowering size.

Desert_Son, dont give up. Keep them for another season and see what happens. Maybe they are still not very mature. I have planted so many Polyanthus Tuberose and seem to find only a faint fragrance, if any. But I'm not giving up! Now if I could just get more fragrant violets in my garden, I'd be in heaven! Freesias, Polyanthus & violets! Ahhh.... Clare, I have hunted for freesia bulbs here in Fort Lauderdale with no luck. Was in San Francisco a while back and my poor daughter was the driver from one nursery to another to hunt them down. Returned home with a couple of dozen bulbs and happily, most are blooming with their amazing fragrance. Your clump is absolutely beautiful. Only the white and yellow ones have flowered here. Dont know what will happen when the tropical rains come however! Probably lose all of them to rot! What a magnificant fragrance!

You can cut the flowers at the base anytime. Be sure to leave the foliage because the plant needs the energy stored in the leaves to make new bulbs for next year so the foliage needs to stay on the plant. The flower buds will open when the stalk is placed in water.

It reminds me of my gladiolus foliage when I was a new gardener. I was told to destroy them. Instead I experiented after the foliage aged. Removed it. Dug up the corms and soaked them a couple of hours in a malathion solution (only chemical killer I had). Dried and replanted a month later. Had clean foliage the following year. Not saying this is your solution ...... but if they're going to be goners and you have malathion ....... It may be a virus and that can't be treated. I googled freesia thrip and found this. "In many thrips species, by the time their damage is observed, such as after buds open, the thrips may no longer be present. Some abiotic disorders, pathogens, and certain other invertebrates can cause damage resembling that of thrips. For example, various true bugs and mites also stipple foliage;"
