Winter hardiness of Muscari

Muscari

The winter hardiness of Muscari is characterized by the bulbs' ability to withstand frosts down to –25…–35 °C and adapt to USDA hardiness zones 4–9. The high survival rate of the crop allows it to be grown in open ground without the need for annual lifting.

In the reference 7 varieties crop Grape hyacinth, where this is mentioned in the description.

To assess the winter hardiness of Muscari, visual observations in open ground are used: overwintering success is determined by the preservation of generative capacity and the timely onset of the growing season. The species M. armeniacum and M. botryoides demonstrate high resistance; however, in the absence of snow cover in regions with temperatures below –10…–15 °C, winter hardiness may decrease, requiring the use of mulching.

A physiological feature of winter hardiness is the crop's ability to produce leaves in the autumn, which remain under the snow and maintain viability until spring. The stability of this indicator also depends on agrotechnical conditions: in waterlogged soils, winter hardiness decreases due to the risk of damping off and bulb rot during the winter-spring period.
