When it comes to plants, there are two categories: annuals and perennials. While they may appear similar at first glance, these plant types have distinct characteristics. Let’s delve into the pros and cons of each, allowing you to make an informed decision.

Annuals

Annual plants, as their name suggests, live for a single growing season, necessitating replanting each year. This aspect, often viewed as a disadvantage, can actually be advantageous as it enables you to redesign your garden annually.

Another advantage of annuals is their tendency to produce an abundance of flowers, making them an excellent choice for vibrant displays. However, they do require more maintenance than perennials, necessitating regular watering and fertilization.

Perennials

Perennials, on the other hand, return year after year without the need for replanting. While they may not yield as many flowers as annuals, their low-maintenance nature compensates for it.

Once you’ve planted a perennial, it generally requires minimal attention until it’s time for trimming in the fall. Furthermore, perennials often display greater resilience to extreme weather conditions, making them suitable for regions with hot summers or cold winters. However, it’s important to note that perennials may take a few years to reach their full potential, lacking instant gratification.

To achieve blooms in spring, summer, and fall, consider the following guidelines for bed size, plant quantity, and spacing to create an effective perennial planting. Keep in mind that maintaining a perennial bed requires time and effort.

Bed Size

The size of the bed depends on the amount of time you can dedicate to its maintenance. Remember, perennial plantings require substantial attention. Adjust the size accordingly.

Plant Selection and Placement

For a good distribution of blooms, incorporate irises, phlox, and chrysanthemums in the bed, placing them strategically according to their specific flowering seasons. Avoid excessive use of irises or large plant groups. Similarly, introduce a few varieties of novae-angliae and novibelgi hardy asters for September bloom. Complement these choices with perennials such as Achillea ptarmica, anthemis, aquilegia, Campanula persicifolia, coreopsis, dictamnus, and gypsophila.

Grouping and Spacing

Plant in groups of three, with a spacing of 15 inches between each plant for the mentioned perennials. Towards the edge of the bed, consider including Anemone japonica varieties, dwarf asters (hardy), Campanula carpatica, Dianthus deltoides, D. latifolius, and geums. Plant these in groups of three, with a spacing of 6 to 12 inches.

Early Spring Blooms

For early spring flowers, interplant tulips and narcissi in groups throughout the bed. Along the edge, incorporate arabis, aubrieta, Alyssum saxatile, A. saxatile citrinum, Phlox subulata varieties, and pansies.

Perennial Flowers for a Small Garden

Choose perennial flowers whose growth habit and flower size are suitable for a small area. Consider the following options: Alyssum argenteum, Arabis albida, various aquilegia, various dianthus, Aster subcoeruleus (Himalayan Daisy), bleedingheart, Campanula carpatica and C. persicifolia, lily-of-the-valley, dwarf Delphinium chinense, candytuft, forget-me-not, dwarf chrysanthemum, Geum borisi, Gypsophila Rosy Veil, various heuchera, Hemerocallis Goldena, Lychnis flos-cuculi, Nepeta mussini, Plumbago larpentae, various primula, pyrethrum, Lilium tenuijolium, L. concolor, and L. flavum, Iceland Poppy, peonies (P. tenuifolia and P. latifolia), Phlox divaricata and P. decussata, and Veronica incana and V. amethystina.

Determining which option is better, annuals or perennials, ultimately depends on your preferences and gardening goals. If you desire an array of colors and variety in your garden, annuals are the way to go. Conversely, if you seek low-maintenance plants that reliably return each year, perennials are the ideal choice. Whichever you select, conduct thorough research beforehand to align your expectations accordingly.
