Annuals for Full Sun and Shade

Most annuals thrive in sunny conditions, especially those bred for strong flowering, like zinnias, cosmos, and marigolds. These full sun annuals provide reliable colour from early summer through autumn. In contrast, a few types of annual plants can tolerate light shade, such as Nicotiana or Browallia, which still produce blooms under dappled cover.

At Tantalus Plant Nursery, our selection of annual plants for sale includes both sun-lovers and varieties suited to partial shade. Whether your garden gets full exposure or is a mix of light and shadow, we grow plants that suit both conditions, ready for planting across Irish gardens. 

Long-Flowering and Vibrant Summer Annuals

Annuals that bloom all summer are a favourite for containers, beds, and borders. Once established, they’ll flower continuously with minimal maintenance. Our most popular summer annuals include cosmos, calendula, scabiosa, and sweet peas—all chosen for their long flowering season and reliability in Irish gardens.

Unlike perennials, an annual plant completes its full life cycle in one growing season. That means you get fast results and maximum colour. These garden plants are perfect for adding seasonal highlights or filling gaps left by spring bulbs and early perennials.

Container-Friendly Annual Plant Varieties

Many of our annuals are ideal for pots, hanging baskets, or window boxes. Compact forms of snapdragons, petunias, and callistephus perform well in containers, offering steady flowering through the season with regular watering and feeding.

For small spaces or patios, container-grown annuals are an easy way to create impact. Our nursery offers a wide range of annuals, making it easy to establish displays quickly. You can mix annuals with trailing varieties, spring annual flowers, or even herbs to create vibrant and practical container gardens.

Why Choose Our Irish-Grown Annual Plants

Our annuals are grown in Cork, carefully raised from seed under local conditions, so they’re garden-ready when they reach you. These aren’t imported or pre-packed; each plant is selected to suit the Irish climate and performs reliably in our outdoor gardens from late spring into autumn. You can learn more about us and what we do on our Homepage.

We grow a wide selection of summer favourites, including Begonia, Calibrachoa, Dianthus, Fuchsia, and Verbena, ideal for beds, borders, pots, or baskets. So if you're a seasoned gardener or planting your first summer display, our hardy and half-hardy annuals arrive strong and ready to bloom.

Frequently Asked Questions About Annual Plants

What is an Annual Plant?

An annual plant grows, flowers, and sets seed all within one season. Once it blooms and finishes flowering, its life cycle ends. This makes annuals ideal for fast, eye-catching garden colour, often blooming for months on end if watered and fed regularly.

What Does Annual Plant Mean?

The term “annual” refers to the plant's lifespan, lasting only one growing season. Unlike perennial plants that return year after year, annuals give one strong display before finishing. They're excellent for filling spaces, pairing with flowering perennial plants, or refreshing borders each season.

When Can I Plant Annuals Outdoors?

Most half-hardy annuals need to be planted out only after the risk of frost has passed—typically in late April to early May. Hardy annuals, like Calendula or Pansy, can go in earlier and tolerate some cold.

Can I Mix Annuals With Other Plants?

Yes. Annuals work beautifully alongside perennials and bulbs. They're especially good for filling gaps or providing bold colour while slower growers establish.
