Shrub veronica is commercially available in many different varieties. Due to its low growth 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.
Hebe addenda can be overwintered outdoors provided it is adequately sheltered
Hebe addenda only tolerates low minus temperatures
Even if it is often stated differently in plant descriptions, the Hebe addenda variety is not hardy. It tolerates frost down to a temperature of minus 5 degrees, but 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 the tub. Then you can overwinter them frost-free in the house in winter.
Hebe addenda pull in the garden
If you want to cultivate Hebe addenda in the garden, plant the perennials as early as possible in the year. Then the plants have enough time to form roots to survive the winter better.
At the latest when the temperature outside drops to five degrees or less, mulch the soil around the shrub veronica. Cover the plants with brushwood or, even better, pine 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 bucket frost-free
If you have Hebe addenda planted in a bucket, bring the pot inside 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 wintering.
In winter, the Hebe addenda is only watered very moderately, so that the root ball just stays moist.
Get used to warmer temperatures slowly
In the spring, get the ornamental shrub out of its winter quarters and slowly get used to the warmer temperatures. Place the planter on the patio by the hour.
tips
Hebe addenda has a very long flowering period. If you cut them back right after the first bloom, you will encourage a second bloom.
