Gladiolus cardinalis I am on the verge of buying this wonderful plant from San Francisco the problem I may have is it a southern hemisphere growing tuber so would it be possible to reverse its growing season to our northern hemisphere growing season if so how. I thought maybe store the corms until maybe March/April then maybe it would delay any new growth



It is temperature and light that triggers the state of bulb growth, Steve, rather than the calendar. We grow a few South Africans which flowqer in our summer (their winter). It may have a slight hiccup the first year but should then settle down. Plant as normal.

Actually, if your gladioli have been raised in California they were grown in the northern hemisphere and so will flower at the right time anyway.

Hi, just remember that they are frost tender, Derek.

I have a couple of the South African glads I have grown from seed, and they are winter-flowering types like the one you want. They flower in the winter and die back during the summer, and will start growing again next month.
