Strauchveronika is available commercially in many different varieties. Because of its low height, Hebe addenda, like Hebe andersonii, is particularly popular. Unfortunately, the pretty ornamental perennial is only partially hardy, so you have to provide frost protection in good time.
Is the Hebe Addenda hardy and how do I protect it in winter?
Hebe Addenda is only partially hardy and can tolerate frost down to -5 degrees Celsius. For sufficient winter protection in the garden, mulch the soil and cover the plant with brushwood or pine branches. It can overwinter in a bucket frost-free at 5 to 10 degrees Celsius.
Hebe addenda can only tolerate low temperatures below zero
Even if it is often stated otherwise in plant descriptions, the Hebe addenda variety is not hardy. It can tolerate frost down to minus 5 degrees, but even then only for a short time.
If you want to grow Hebe addenda in the garden, you must therefore ensure good winter protection in good time in autumn.
It is even better to grow this shrub veronica variety in a pot. Then you can overwinter them in the house frost-free in winter.
Pulling Hebe addenda in the garden
If you want to care for Hebe addenda in the garden, plant the perennials as early in the year as possible. Then the plants have enough time to form roots in order to survive the winter better.
When the temperatures outside drop to five degrees or less, mulch the soil around the shrub veronica. Cover the plants with brushwood or, even better, fir branches.
As soon as it gets warmer again in spring, remove the winter protection and slowly get the Hebe addenda used to more light again.
Overwinter shrub veronica in a pot frost-free
If you have planted Hebe addenda in a container, bring the container into the house as soon as it gets too cold outside. Overwinter the plant in a location that meets the following requirements:
- as bright as possible
- cool at five to ten degrees
- moderately humid
Check the shrub veronica for pests before overwintering.
In winter, the Hebe addenda is only watered very moderately, so that the pot ball remains just moist.
Get used to warmer temperatures slowly
In spring, take the ornamental perennial out of its winter quarters and slowly accustom it to warmer temperatures. Place the planter on the terrace for hours.
Tip
Hebe addenda has a very long flowering period. If you cut them back immediately after the first flowering, you will encourage a second flowering.
