Judy: I've grown 'commercial' freesias for 12 years, sometimes with little trouble, but all seem to pick up viruses eventually, sometimes even after the first year. We have significant aphid and white fly attacks, particularly in greenhouses, and I've assumed that that's the source of viruses. It's a good idea to get rid of any freesia, brand new or in those carried over, that show the characteristic virus-induced leaf variegation. All of the Dutch bred freesia that I've grown became virus-infected and I presume that that's the reason for the admonition. The only freesias that seems to remain virus-free for years and years are F. alba (I've had them growing since 1990). Roy
