Weekly Garden tip by Isaac Walker

Three Fall Flowers: Part 2 - Sedum ‘Autumn Joy’

While there are many varieties of Sedum, the one we will discuss today is generally recognized as ‘Autumn Joy.’ This is, in fact, not a true sedum. Botanists relabeled upright stonecrops as a distinct genus, Hylotelephium, in the 1970s. In common gardening discussion, however, Sedum is still used as the most recognizable common name. Perhaps the most recognizable and popular of sedums and stonecrops is the ‘Autumn Joy’ variety, a drought-tolerant perennial with succulent leaves that grows to a height of one to two feet. Its pink crown of fall blooms makes it a great eco-friendly plant as it provides for late-season pollinators. The cultivar ‘Autumn Joy’ was produced in Germany in the 1950s but quickly became popular in the U.S. as well for being a low-maintenance succulent, with a broad season of floral interest. If you are looking for a plant to add contrast to a garden, or just something that is beautiful and easy to grow, this sedum is a perfect choice for a variety of setting.

Ask a Master Gardener by Helen Vanella, Master Gardeners of Greene County

Questions……..
I collected seeds from a giant allium. When is the right time to plant these?

Answer…….
The best time to plant these seeds is late summer or early fall right after the seed heads dry up and are still fresh. They can also be stored in the refrigerator over the winter, keeping chilled, until early spring. Cold treatment over winter is necessary to promote germination. The seeds can be planted inside or in a greenhouse in early spring. Soil temperature for outside planting should be around 55 degrees. Patience is key when starting from seed because it can take two to four years to go from seed to a large enough bulb size to produce a flowering plant. Seeds should be planted in a well-drained potting soil which has been amended with compost. Seeds should be planted from one-quarter to one inch deep. Many of the giant allium cultivars are hybrids and the offspring may be different than the parent plant.
