What are hardy plants? What does it mean?
What is a ‘hardy’ plant and what does it mean? An amusing story sprang to mind when ‘Sid’ enquired about the hardiness of a plant I uploaded see
In an effort to give a very general ‘across the board’ guide to the level of cold a plant can withstand plants may be classified in to several groups.
‘hardy’ = -15C
‘frost hardy’ = -5C
‘half hardy’ = 0C
‘frost tender’ = +5C This last item applies to plants which may be damaged below this temperature.
This is only a guide and there are thousands of exceptions. But gardeners can always grow plants to lower temperatures if their plant is well drained and the compost is kept ‘near-dry’ through the winter. Larger root balls and leaf removal also have a positive effect in enabling a plant to pull through colder climes and if you visit the ‘Gardening Guides’ section of my ‘Gardening World’ sub-site you will find a lot more useful information.
But ‘cold’ is a relative thing. . . . . . . .
A few years back I was talking about my garden to a group of Russian garden designers and landscapers when the question of cold hardiness came up. And to my embarrasment I can still recall talking of -15C etc etc and watching the grins spread before my audience. Talk about teaching grandma to suck eggs! I eventually cottoned on and we all had a good laugh about it.
The next day they showed me how householders remove the glass from their greenhouses each autumn because the cold will crack the glass. Then they took me to a famous garden where even the BRONZE STATUES where protected from the cold! LOL
