When looking at backyard landscape design you can really tell how old the people are that live there by looking into a garden. For instance if you are like my Father there was not much point in having flowers it was all about the lawn and how green and lush it was. The lawn was lovingly cared for with the weeds hand weeded.
The next generation are now settling into a growing stage of lives where you grown just about everything and anything in pots and planters. Today this generation is in too much of a rut with no time to do anything much and these people would tend to have fancy pots of Yucca’s or other equally low/no maintenance plants. They would also have either paved or had some faux grass put in as they have no time to mow lawns etc. So if you don’t want people to know how old you are change the landscape of your garden.
