What Not To Plant With Hydrangeas?

As a gardener, it’s essential to be mindful of the plants you place together in your garden. While hydrangeas are known for their beautiful blooms and lush foliage, there are certain plants that should not be planted alongside them. Understanding which plants do not pair well with hydrangeas can help you create a harmonious and thriving garden.

Sunflowers are stunning plants that bring a vibrant burst of color to any garden. However, they have different needs compared to hydrangeas. Sunflowers thrive in full sun and hot conditions, whereas hydrangeas prefer some shade to thrive. Planting sunflowers near hydrangeas may result in the hydrangeas not receiving the adequate shade they need to flourish.

Lavender is a beloved herb known for its fragrant blooms and calming properties. While lavender adds an aromatic and visual appeal to a garden, it may not be the best companion for hydrangeas. Lavender thrives in sunny locations with well-drained soil, while hydrangeas prefer slightly acidic and moist soil. Planting lavender near hydrangeas may disrupt the soil balance and prevent both plants from thriving.

Rosemary, another popular herb, is a versatile plant used in cooking and for its medicinal properties. However, rosemary and hydrangeas may not be the best match in the garden. Rosemary requires well-drained soil and plenty of sunlight, which contradicts the moisture-loving and partial shade preferences of hydrangeas. Planting these two together could lead to competition for resources and hinder their growth.

Daisies are cheerful flowers that brighten up any garden with their simple beauty. While daisies are easy to grow and low-maintenance, they may not complement hydrangeas well. Daisies prefer full sun and well-drained soil, unlike hydrangeas that thrive in partial shade and moist conditions. Mixing these plants together may result in one overshadowing the other and impeding their growth.

Peonies are known for their large, ruffled blooms and enticing fragrance. These perennial flowers are a favorite among gardeners for their romantic appeal. However, planting peonies alongside hydrangeas may not be the best idea. Peonies prefer rich, well-drained soil and full sun, while hydrangeas prefer slightly acidic soil and partial shade. The differing soil and light requirements of these plants could lead to stunted growth and unhappy plants.

Salvia, a striking flowering plant commonly found in gardens, adds vibrant color and attracts pollinators. While salvia is a beautiful addition to any garden, it may not be the ideal companion for hydrangeas. Salvia thrives in full sun and well-drained soil, while hydrangeas prefer partial shade and consistent moisture. Planting these two together may result in one plant overshadowing the other and struggling to thrive.

Petunias are popular annual flowers prized for their bright blooms and versatility in garden beds and containers. However, petunias and hydrangeas may not be the best pairing in a garden. Petunias prefer full sun and well-drained soil, while hydrangeas thrive in partial shade and moist conditions. The differing light and soil preferences of these plants could lead to one plant outcompeting the other and affecting their growth.

Hostas are shade-loving perennials with attractive foliage that adds texture and color to garden beds. While hostas are prized for their ability to thrive in shady areas, they may not be the most compatible plant to grow alongside hydrangeas. Hostas prefer consistent moisture and shade, whereas hydrangeas require some sun and well-drained soil. Mixing these plants together could result in one plant struggling to establish itself and impacting the overall aesthetic of the garden.

Daylilies are vibrant flowering plants that bring a burst of color to garden borders and beds. Daylilies are known for their low-maintenance nature and ability to thrive in various conditions. However, daylilies and hydrangeas may not be the best companions in a garden setting. Daylilies prefer full sun and well-drained soil, while hydrangeas thrive in partial shade and slightly acidic soil. Planting these two together may lead to one plant overpowering the other and affecting their growth.

Black-eyed Susans are charming wildflowers with cheerful yellow blooms that attract pollinators to the garden. While black-eyed Susans add a pop of color and wildlife interest to a garden, they may not be the best match for hydrangeas. Black-eyed Susans prefer full sun and well-drained soil, whereas hydrangeas thrive in partial shade and moist conditions. Pairing these plants together could lead to one plant outcompeting the other and impacting their growth.

In conclusion, while hydrangeas are stunning plants that enhance the beauty of any garden, it’s crucial to consider their companions carefully. Avoid planting sunflowers, lavender, rosemary, daisies, peonies, salvia, petunias, hostas, daylilies, and black-eyed Susans near hydrangeas to ensure the optimal growth and health of your garden. By understanding the individual needs and preferences of plants, you can create a harmonious and flourishing garden that brings joy and beauty to your outdoor space.
