Q.Large planters
Please could you advise what sort of shrubs would be good for these planters soil.is yellow clay mainly
I dont wants them to grow massive
But want colour all year
Any ideas please

What type of sunlight does your area have. Full sun, partial sun?
I am unable to determine the depth of your planters. A minimum of 6 inches would be needed for annuals. Shrubs would need a much greater depth of soil, depending on the variety.
