Companion Plants
Create a soft summer border with these warm tones:
Perennial. Magnificent flower heads in lively shades of red, rose, or lavender. Yarrow grows tall and wide, with fine, feathery foliage and long stems that are excellent for cutting. They are a good choice near the vegetable garden, as they attract beneficial insects, pollinators and butterflies, and repel harmful pests. As an added bonus, they are one of the best companions for roses, serving similar pest control duties, without drawing undue resources from the soil. Plants are very easy to grow, tolerating heat, drought, salt and poor soil conditions. They will easily naturalize into the garden, provided soil is well-draining and they receive adequate light.
Location: Sunny border, Wildflower meadow, Coastal garden, Rose garden
Bloom Period: June to September
Height: 24”
Plant Spacing: 12-24”
Perennial. A striking, blue beauty that happens to be a pollinator magnet! Bees and butterflies will swarm the huge, 4” flowers over a long blooming season. Ruffled petals will open around a pale central disc. As the bloom matures, this disc becomes studded with dark stamens to give the characteristic “pincushion” appearance. Plants tolerate a variety of soil types, but will thrive in rich, well-draining soil. Drought tolerant once established, they will benefit from regular watering and fertilization in their first year.
Location: Mid-border, Cut flower garden, Rock garden
Bloom Period: July/August
Height: 28”
Plant Spacing: 12-18”
Annual. Prolific mounds of cheerful lemon-yellow flowers. ‘Opera Supreme’ are a superb trailing series, producing a showstopping cascade of 2’ flowers all summer long. Ideal for hanging baskets or as a seasonal ground cover, plants are vigorous and self-cleaning.
Petunias are a popular summer annual, prized for their beautiful blooms and versatility in the garden. Attracting pollinators and repelling harmful insects, they are an excellent companion for the vegetable garden. Mounding varieties put on a thrilling display in the landscape, and trailing varieties form a graceful ground cover or hanging basket. Plant in light, fertile, well-draining soil. Water regularly and feed container plants every 1-2 weeks.
Location: Ground cover, Mixed container, Hanging basket
Bloom Period: June to September
Height: 6-10”, spreading to 3.5-4’
Plant Spacing: 12-18”
Annual. A classic variety of this popular annual - and one of my personal favourites. A true workhorse, ‘Carpet of Snow’ is one of the most versatile plants in the garden. As an ornamental, it can be tucked into the corners of raised beds, blanket the edge of a border bed, or drape gracefully over the sides of a mixed container. As a vegetable companion, its lovely, sweet fragrance attracts an abundance of pollinators and repels harmful insects. A low growth habit allows it to act as a living mulch. Both the leaves and flowers are edible, with a light peppery taste. Plants prefer moist, loamy soil, and providing a monthly dose of balanced fertilizer will be heartily rewarded.
Location: Front of border, Hanging basket, Mixed container, Vegetable garden
Bloom Period: June to October
Height: 6”, spreading to 12”
Plant Spacing: 5-8”
