I spent this Winter trying to design trays that complement the Jacaranda that I like to grow.
Looks great. I do faux bonsai and miniature gardens and love the look in hypertufa planters. You can also make hypertufa slabs that look like slabs of rock and leave crevices and holes to plant your bonsai.
My faux bonsai..........I buy bonsai starters and plant in hypertufa planters. The starters are slow growers so I just root prune them every couple of years. I don't train the trunk or branches.
