    Unlike most of the hybrids, species tulips tend to stick around and even multiply over the years. Many are perfectly proportioned to mingle with alpine cushions and mats. Check them out under "Bulbs" on www.gardenimport.com

    Dugald Cameron offered this useful advice in his most recent newsletter: “What?” you ask. “We can plant in the summer?” Gardeners often stop planting when summer rolls around for fear that it won’t work. This is a fallacy based on confusion between transplanting and planting. Transplanting in summer is risky: established plants rely on fine “feeder roots” for moisture and nutrients. When these plants are lifted from the garden, these essential feeder roots are destroyed, the balance between roots and foliage is upset and the plant often withers and dies. Not so with potted plants. Their entire root structure remains intact inside the container. To give your container-grown plants a good start, dig a hole that’s wider than the pot, but about the same depth. Add compost or well-rotted manure. Slip the plant from the container and loosen the roots a bit to encourage them to grow outward, into the soil. Position the plant so the crown is level with the soil surface, backfill the hole with soil, gently tamping it down to remove air pockets. Make a little dyke around the plant to help trap rainfall, water well and you’re done!"

    Our members, Alice d'Entremont of Ouest-Ville Perennials, Jeff and Derek Mason of Mason House Gardens, Christine Halbot of Northcott Gardens in Woodville, the Cooks of Blossom Hill Nursery and Dugald Cameron of Gardenimport, carry some spectacular peonies. The hybrid pictured here was developed by Canadian-born A.P. Saunders. Sources of rock-garden peonies are Alpine Plants, owned by Mandy Botincan, and Wrightman Alpines, owned by  Harvey and Irene Wrightman. Ideally, bare-rooted peonies should be planted mid-autumn .
