“But I always see Roses at Woolies and I can buy Chrysanthemums in flower, in pots from my local nursery year round?” Susan, Susan, Susan. Most flowers one can buy from stores are grown in a greenhouse, which means the climate inside those greenhouses is manipulated to ensure that specific species can be grown year round.
It’s the same growing method that allows us to grow tropical plants in the UK or arid plants in Russia. We create small micro climates for these plants and grow them on mass for retail purposes. Place any of these plants grown in a greenhouse outside in your garden, and they will almost always die in a very short time. Why? They are not adapt to the local climate, they spent their entire life in a controlled environment and as soon as they are exposed to irregular temperatures or torrential rain, they wilt and die.
