What Annuals Bloom All Summer?

| |

Are you wondering what annuals bloom all summer? With proper care, the answer would be most annuals bloom all summer.

Being a gardener with large perennial gardens, you would think that I wouldn’t need too many annuals. Well, you would be wrong, and here is why……

Color all Summer

Because annuals bloom all summer long, they give my perennials which ebb and flow in when they bloom and how often they bloom, the consistency of season-long color.

I also fill my pots, hanging baskets, and window boxes with annuals. Because I love to garden, I have a pretty hefty budget for my yearly annuals.

What Annuals Bloom in the Sun?

These are my favorites for the sun. The symbols I will put after each one pertains to the application (P)-Pots, (W)-Windowboxes, (H)-Hanging Baskets, (G)-Fill in my Gardens, (V)-Vegetable Garden

  • Marigolds (V) – I love to plant marigolds in my vegetable garden. There is a host of reasons that they are beneficial to your vegetable garden and bonus… they are edible.
  • Petunias (Supertunia) (P) (W) (H) (G) – I prefer the wave of spreading petunias as they don’t need to be deadheaded and they fill in beautifully in a garden or trail beautifully over pots, window boxes, baskets or walls.
  • Geraniums (P)
  • Cosmos (G) – I plant these in the back of my perennial garden. They grow tall and flower all summer long. They are a beautiful flowy backdrop of color.
  • Lisianthus (G)(P) – These are a beautiful fill-in for the perennial garden and also can be grown in pots.
  • Cleome or Spider Flowers (G)(P) – I love these unusual flowers. They can be spectacular in the garden but also a thriller for your pots.
  • Gomphrena Globosa ‘Ping-Pong Lavender’ (P)(G)- This beauty is a stand-alone plant that can fill a pot or even be planted in the garden.
  • Strawflowers (P) – I absolutely love strawflowers in my pots. They are so interesting and unusual.
  • Angelonia (P)(W)(G)
  • Lantana (P)(W)
  • Lobelia (P)(W) – I use lobelia for spots where I want a touch of blue
  • Osteospermum (P)(W)(H)-These beauties are like daisies in a variety of colors. Love Them!

What Annuals Bloom in Shade?

These are my favorites for shade. The symbols I will put after each one pertains to the application (P)-Pots, (W)-Windowboxes, (H)-Hanging Baskets, (G)-Fill in my Gardens

  • Double Impatiens (P)(W)(H)(G)-This is my all-time favorite shade annual. Unlike a typical impatient, this has a rose-like bloom that is the prettiest flower that can handle shade.
  • Impatiens (P)(W)(H)(G) – This power flower is perfect for shade where you want some color. In my area, they are cheaper than double impatiens so I use them more liberally in shady areas.
  • Begonia (P)(W)(H)
  • Super Wave Bouquet Wishbone Flowers (P)(W)(H) – These delicate beauties are great for the shade.
  • Fushia (P)(W)(H)
  • Bacopa (P)(W)(H) – These come in white, pink, and lavender colors.
  • Diamond Frost Euphorbia (P)(W)(H) – These wispy white plants make a statement
  • Hippo Rose Polka Dot Plant (P)(W)(G) – Fill your shade garden in with mounds of color with these
  • Sweet Alyssum (P)(W)(H)(G) – I use this beautiful plant as a filler in both sun and shade in my garden
  • Begonia (P)(W)(H)(G)

Vines and other Foliage

  • Optic Grass
  • Asparagus Fern
  • Vinca Vine

How to Care for your Annuals

  • Regular Watering and Proper Drainage
  • Good Soil – I use Miracle Grow Moisture Control for my pots, windowboxes, and hanging baskets.
  • Nutrition – Osmocote has been my favorite product for fertilizing my flowers. I typically use it in pots where I’m using some older soil or in my actual gardens. You don’t need it if you are using Miracle Grow Soil but you could give everything a little shake of it in mid-summer.

  1. Thanks for the recommendations, Lynn! I’m still adding to my flower beds so this post is timely! Pinned!

    1. I haven’t even bought mine yet. We can’t plant until after the 15th and the weather is so crumby here it might be even later.
