The two Sucrette cuttings I have from Harvey were started the first week in March. Both rooted quickly, are now in one gallon pots and have five inches of growth from the original cutting.
All the eBay cuttings which took weeks to get here died, even though they were alive when they arrived, were well packaged and some with green sprouts. One or two even developed roots briefly, look like they were going to "take", then died. All of these I started in April or May, so my guess is that it was too late in the season for them. Or perhaps they didn't survive possible "death rays" of the California postal processing? Or the rooting hormone which worked great Feb./March had expired and had a toxic effect?
I feel your pain, because these were some really special varieties.
