@gemini_sage Neal, freesias are so easy to grow in my climate and you would go nuts with the fragrance filling the whole garden, not to mention how you would blend in the different colour hues into your garden or at work.All mine are grown outside in pots or polystyrene boxes, without any cover whatsoever and not lifted.Having said that, the 4 boxes of seedlings are jammed full after 4 years growth and going downhill this year.Need to separate them, new soil with plenty of grit.
One of the tasks when one first buys freesia corms from the big Dutch growers/importers, is to dehusk them.Look for any signs of fusarium and ask for a refund or replacement.It's hopeless to try and save them, burn them or trash them, fusarium will spread and live in your soil for years.Pollinate your blooms, sow the seed and you will have heaps.
I know in your climate it must be a challenge to keep them going year to year.
