When it comes to the hardiness of cyclamen, there are a few different species and varieties to consider. The hardiness of cyclamen can vary depending on the specific type and where they are being grown. Here are some of the hardiest cyclamen varieties that you can consider for your garden:
1. Cyclamen hederifolium: This is one of the hardiest species of cyclamen. It is native to Mediterranean regions and can withstand colder temperatures. It is often grown for its beautiful silver-patterned leaves and delicate pink or white flowers. Cyclamen hederifolium is typically hardy to USDA zones 5-9.
2. Cyclamen coum: Another hardy species, Cyclamen coum is known for its early flowering and ability to tolerate cold temperatures. It produces vibrant pink or white flowers that brighten up the winter garden. Cyclamen coum is also hardy to USDA zones 5-9.
3. Cyclamen purpurascens: This species is native to alpine regions of Europe and is known for its cold tolerance. It has fragrant flowers that range in color from pink to purple, and sometimes even white. Cyclamen purpurascens is hardy to USDA zones 4-8.
4. Cyclamen cilicium: Native to Turkey, this species is one of the hardiest cyclamen you can find. It has attractive leaves with silver markings and produces beautiful pink or white flowers. Cyclamen cilicium is hardy to USDA zones 4-8.
5. Cyclamen persicum: While not as hardy as the previous species mentioned, Cyclamen persicum is a popular variety for indoor cultivation. It is often sold as a potted plant and can be enjoyed as a houseplant during the winter months. Cyclamen persicum is not as cold-tolerant and is typically grown in USDA zones 9-11.
It’s important to note that even the hardiest cyclamen varieties may still benefit from some protection during extreme cold temperatures, especially if you are growing them in colder zones. Providing a layer of mulch or covering the plants with a frost cloth can help protect them from harsh winter conditions.
In my personal experience, I have grown Cyclamen hederifolium in my garden in USDA zone 6. I planted the tubers in early fall, following the recommended planting depth of about one inch and spacing them six inches apart. I created low mounds in a shaded area of my garden to mimic their ideal habitat. The plants established well and formed beautiful colonies over time. During the summer, I made sure to water them sparingly to prevent the roots from dying back while they were dormant.
When choosing cyclamen for your garden, consider the specific hardiness zone you are in and select varieties that are suitable for those conditions. By providing the right growing conditions and a little extra care during extreme weather, you can enjoy the beauty of cyclamen in your garden year after year.
