Dierama, commonly known as angel’s fishing rod or wandflower, is a beautiful flowering plant that adds grace and elegance to any garden or landscape. When it comes to determining the suitable zone for dierama, it is important to consider its hardiness and adaptability.
In general, dierama plants are best suited for USDA hardiness zones 8 and above. These zones have milder winters and longer growing seasons, which provide the optimal conditions for dierama to thrive. However, it is worth noting that dierama can potentially lose winter hardiness even in these warmer zones.
While dierama may technically be able to survive in zone 7, it is important to acknowledge that they can be quite fickle and may struggle to establish themselves in colder climates. In our personal experience as gardening enthusiasts, we have attempted to grow dierama in both zone 7 and 8, but unfortunately, about two-thirds of our attempts to get them established in the ground in zone 7 failed.
It is essential to provide dierama with a suitable growing environment to increase its chances of survival. This includes planting them in a rich, well-draining soil and ensuring they receive adequate sunlight. Additionally, providing a protective mulch layer around the base of the plant during colder months can help insulate the roots and protect them from freezing temperatures.
While dierama may not be as reliably hardy in zone 7, there are still options for gardeners in these colder regions. Consider growing dierama in containers or raised beds, where you have greater control over the growing conditions. This way, you can provide extra insulation or move the containers to a protected area during the winter months.
Dierama plants generally thrive in USDA hardiness zones 8 and above. While they may be grown in zone 7, their winter hardiness can be questionable, and success rates may vary. It is crucial to provide them with optimal growing conditions and consider alternative methods, such as container gardening, in colder climates to increase their chances of survival.
