How to choose perennials that will last for years

The most common mistake is buying whatever is in flower in the shop. We explain how to choose by site and save yourself disappointment.

Look at the site first, not the plant. How much sun does it get? Does the soil dry out in summer, or is it always moist? Are there trees with roots nearby? Once you know this, choosing is suddenly easy, and the plants will reward you.

Second: buy plants that match each other in height and flowering time. Then the border looks good from spring to winter, not just for two weeks.
