In England, there is a naturally formed volcanic rock called tufa. It was commonly used to make animal watering troughs. Over the years, it became very expensive and very hard to find.  So, hypertufa was invented. Hypertufa is made from  cement, peat moss, and other natural ingredients. This mixture is similar to concrete but much lighter and more porous. It also looks very similar to the traditional tufa rock.

Plants love hypertufa.  Because it is porous, plant roots will actually work their way into the flowerpot.  The flowerpots also have an insulating quality to them protecting plants tender roots from over heating.   Hypertufa can handle the elements.  The sun will not fade them as it will plastic pots.  They can withstand temperatures as low as -40°F without cracking.  I have read articles about hypertufa pots on gardening forums where people have claimed to have their hypertufa pots for over 20 years. 

Here is my first attempt at this new for me ~  but very old English gardening tradition:

Earthy looking pots ya got there Mel. I bet it was alot of fun
