Frequently Asked Questions

What pairs well with iris?

In addition to the beautiful combination of iris and peonies, another pairing that works well with iris is the combination of iris and roses. The vibrant hues of iris flowers create a striking contrast against the delicate petals of roses, resulting in a stunning visual display. The diverse range of colors available in both iris and roses allows for endless possibilities, whether it’s a harmonious blend of soft pastels or a bold juxtaposition of vibrant tones. Together, iris and roses create a mesmerizing symphony of colors that enhances any garden or floral arrangement.

What grows iris best?

The key to growing irises successfully lies in providing them with optimal conditions. These vibrant flowers thrive when exposed to full sun, allowing them to receive abundant energy for growth and blooming. In addition to sunlight, it is essential to ensure that the soil has excellent drainage, preventing waterlogging that can damage the iris roots. Providing irises with ample space allows them to spread out and establish themselves, which ultimately leads to more prolific blooming. Adding fertilizer and dividing large clumps can further enhance the chances of seeing vibrant blooms. While it may take some patience, giving irises an extra year to become fully established can result in a more robust and stunning display of flowers.

Can lilies and irises grow together?

Yes, lilies and irises can indeed grow together. Both lilies and irises benefit from having shallow-rooted companions, as it helps to keep their roots cool. Irises are particularly well-suited to grow alongside lilies due to their shallow root systems. The combination of their vibrant colors and complementary shapes creates a beautiful visual display in the garden. Whether it’s the graceful petals of the lilies or the striking blooms of the irises, these two plants can create an enchanting garden scene when grown together.

What is the best ground cover for iris beds?

One of the top choices for covering iris beds is Creeping Thyme. With its dense growth and low height, Creeping Thyme creates a beautiful carpet of tiny, fragrant flowers that not only provides a stunning backdrop for irises but also helps retain soil moisture. Another great option is Corsican Mint, a delicate ground cover that spreads quickly and fills in the spaces around irises. Its tiny, aromatic leaves release a refreshing scent when stepped on and its low growth helps to retain moisture in the soil, keeping the irises happy and hydrated.
