hi , this is my first post , im a bit of a newbie when it comes to growing fruit and veg etc , my first and im sure not my last question is , could someone please explain what , hardy , perennial , half hardy etc means , thanks
Hardy- will withstand frost (down to about -10 deg C)
Half-Hardy - will need some sort of protection (greehouse, horticultural fleece etc) for anything below freezing
Tender - needs to be brought indoors if frost forecast
Perennial - Plant that comes up each year - either same plant, or from seeds it's dropped (or 'set') the previous year.
Perennial, lives for several years, many years for some
Annuals germinate, flower and seed in one growing season.
biennials germinate one year and flower the next
Hardy plants can take our climate and won't die in the frost
half hardy means they'll probably die in the winter - too cold for them
Tender - they will die in the winter
Perennials, biennials and annuals can be hardy, half hardy or tender.
many thanks for your quick replies , that helps alot
That's OK Glen. Not many questions go unanswered here
Half hardy actually means they can't cope with forsts and should be hardened off by day but brought under cover at night till teh frosts are over in mid May for most of mainland Britain. They will die with the first autumn frosts.
Hardy used to mean it could withstand frost but there are, of course, degrees of cold so the RHS has recently revised its hardiness definitions to take account of this.

Tender plants need to be kept indoors, in conservatories or in heated greenhouses as they can't stand cold, let alone frost. Most houseplants are in this category but can go out for some fresh air in summer.
