Long Blooming Annuals and Perennials

May 16, 2023

Let’s face it, summers are short and when we invest in plants we all want annuals and perennials that are long blooming. Flowers that last the duration of the summer are ideal! To achieve this, there are a few things to consider like: the plants you choose, good soil, and the amount of sun the flowers will get. When you come into Eising Garden Centre we can help you find sun or shade loving plants, and soil for your hanging pots, planters or garden beds, but to get started you’ll find some of our favourite plants listed below. First, a little plant primer that will help you make decisions.

Annual? Perennial? What’s the Difference?

Annuals and perennials are in separate areas of the greenhouse because they are plants that we will treat differently in the garden. 

Here is the best way to remember the difference:

  • Annual plants are planted every year, annually, as they will not survive the winter
  • Perennial plant’s roots survive the winter and the plant will regrow each Spring

It’s good to know the difference, right? Now you know what to expect from the plants you buy!

Because Annuals and Perennials are in separate areas of the greenhouse, you might think that the two don’t mix in the garden, but they absolutely do. For example, Perennials can make a great backdrop for Annuals. Or, a well placed pot of Annuals amongst Perennials or shrubs can fill in a gap, or bring a pop of colour once other blooms have faded. Using Annuals, Perennials and Shrubs together can really maximize the beauty in your space! 

If you’re not sure where to start, here are some of our favourite sun loving flowering plants that are easy to grow and long blooming!

Annual Flowers

  • Petunias are one of the most popular blooming annuals for many reasons - there are a wide variety to choose from, they have a wonderful scent, they’re easy to grow and they bloom from Spring until frost.
  • Zinnia flowers are low maintenance, fairly drought tolerant, come in many bright colours, will also bloom continuously from Spring until frost, and will attract butterflies to your garden! All things considered, they are one of the best annuals to grow. 
  • Geraniums are great for containers, hanging baskets, or as bedding plants and come in a variety of leaf shapes and bloom colours. Another reason why these Annuals are so popular is that they are easy to grow and will keep producing flowers late into the Fall.
  • Marigolds come in vibrant colours and are another no-fuss Annual that’s tried and true. These long lasting flowers will also attract butterflies, bees,  lady bugs, and other beneficial insects making them very good companion plants in any garden but especially your vegetable garden.
  • Cosmos will bloom from late Spring into Fall especially if you remove dead flowers. In return, these colourful, daisy-like flowers will attract pollinating insects as well as birds. Cosmos are also fairly drought tolerant making it a delightful and easy to grow Annual.

Perennial Flowers

  • Salvia have spikes of flowers that are long blooming, on plants that are easy to grow, and drought tolerant once they are established. These low maintenance plants will attract butterflies, bees and hummingbirds, and are deer and rabbit-resistant.
  • Coreopsis is another drought tolerant perennial that will bloom summer through fall. Flowers are daisy-like and come in vibrant shades of yellow or red.
  • Coneflower or Echinacea is a daisy-like flower that is drought-tolerant and long blooming. These sturdy plants have flowers in a wide range of colours from chartreuse to pink, orange, red, and yellow. They come in a range of blossom shapes which make them even more intriguing. If that wasn’t enough, they are also loved by birds and pollinators!
  • Rudbeckia, or Black-Eyed Susan are classic perennials that liven up any garden with their sunny colours ranging from yellow to bronzy orange. This durable plant is popular because it is drought-tolerant, pollinators love it, and it’s long blooming.

While most annuals provide a continuous succession of flowers, perennials tend to bloom for two to six weeks. Many perennials will bloom, rest, and then rebloom if you cut off, or deadhead, any spent flowers. A little tender loving care for your annuals and perennials throughout the summer will help blooms last as long as possible. We’ll cover that in our next blog!
