We grow all kinds of roses but we sell those old fashioned and heritage varieties that we know do well in New Zealand. We have had to unlearn lots of things we have read in English (and overseas in general) books because our conditions are quite different. Chinas and teas (in particular) love our climate and many so-called ~once flowerers(TM) will repeat flower here in New Zealand.
The roses and perennials we sell are all made from cuttings or root pieces taken from our gardens, and raised in completely outdoor conditions. Therefore, when you buy, the plants are 100 percent hardened off and ready to go as soon as you get them in the ground.
