What Flowers To Plant In A Raised Garden Bed: Gardeners’ Best Picks
Flowers and vegetables are best suited for raised garden beds. To know what flowers to plant in a raised garden bed is important, especially if you plan on companion planting. Companion plants have many benefits, including producing a greater amount and high-quality yield of vegetables and keeping certain pests away. Also, flowers are attractive – to the human eye and to pollinators, such as bees, butterflies, and other insects that will produce more seeds in your garden. The overall result is a diverse ecosystem, wherein every plant benefits each other. What you get is a garden that is more efficient and low-maintenance.
How Flowers Work In A Raised Garden Bed
To maximize the potential of your raised garden bed, you need to alternate your flowers and vegetables. This will depend on the size of the bed, selection of crops, and types of flowers. Factors like height and sun exposure will determine your layout.
For example, if tomatoes are grown in a bed, they will be the tallest crop. Plant your tomatoes on the north side of the bed, then medium height flowers in the middle, followed by shorter crops such as carrots, in the south row. If you’re growing lettuce, plant it in the middle row, plant shorter flowers in the southernmost row, then a crop similar in size to lettuce, like radishes.
The Types of Flowers
There are four types of flowers, categorized by their life cycle. This is important to know so that you know when to plant them and when to switch out flowers for new ones.
Perennials are flowers that grow every year. Their foliage dies in autumn, and they re-grow the following year. Some perennials can last many years, such as the peony rose, but others typically last only a few years.
Annual flowers complete their growth cycle in one year. They are very robust plants and can withstand frost.
Half-Hardy Annual flowers are more tender compared to annual flowers. They are best suited indoors or in warm locations, but once they mature, they can be gradually exposed to colder outdoor conditions.
Biennial plants require two years to complete their growth cycle. Their seeds are best planted during April. By the next year, they can be transferred to a flowering location.
