You can enjoy the flowers of horned violets all summer long and into autumn. Sometimes they even bloom in winter. But do they survive or do you have to plant new specimens every year?
Are horned violets perennial plants?
Horn violets are usually one to two years old, but can become perennial if they are watered, fertilized and rejuvenated regularly. A good location, frost protection in winter and allowing self-sowing increase their chances of survival.
Horn violets are usually one to two years old
Most commercial horned violets are not designed to last for decades. The majority of them give up after 2 years at the latest. The flowering starts to fade from the second year onwards and the horned violets no longer appear as vital as in the previous year.
Potential for growing old
Basically, every horned violet has the potential to grow old. These plants, called semi-perennials, have a creeping rhizome that survives in the ground throughout the winter and produces new flowers in the spring.
Neglected Horned Violets only live a short time
The reason horned violets don't live long is because they are often neglected. However, if you offer them a perfect location with a good planting distance from one another and do not neglect care, you can extend their existence
Water, fertilize and rejuvenate regularly
Regular watering, sparing fertilization and rejuvenation are crucial. The main reason why horned violets are often not perennial is a lack of energy. They bloom constantly and push themselves to their limits. Therefore the motto is: water well, fertilize regularly and divide every two years.
Rejuvenate the horned violets regularly
Unfortunately, not all varieties are suitable for sharing. It's best to ask at the garden center! If you have a suitable variety, divide it in spring or fall. The plant is previously dug up. After division with a spade, the plants are transplanted to a new location together with fertilizer.
Protect from severe frost in winter
Appropriate frost protection is also important. Most varieties can tolerate frost - some hybrids even tolerate temperatures down to -15 °C. Sensitive varieties should be protected in winter with:
- brushwood
- Leaves
- Fir branches
- Spruce branches
- or fleece
Tips & Tricks
Do not cut off all the wilted flowers. Horned violets like to sow themselves. This means you have the chance to admire horned violets every year, even if you don't have a perennial variety.
