Hot, dry, windy summer weather can be extremely stressful for plants in the garden. Temperatures in Gloucester have hovered near 100º for the last several days, topping out at 102 yesterday. Life seems to be fading from much of the garden. I am usually found hiding inside during intolerably hot weather, however in the late afternoon, I’ll take a stroll to check out heat tolerant plants that shine through the high temps. Several shrubs and perennials are doing well. Here are two that stand out:
The ‘Becky‘ Shasta Daisies, Leucanthemum superbum, that I planted en masse in early spring for our June ‘wedding garden’ are still going strong. I have been rewarded a hundred times over with waves of showy pure white blooms… great for admiring and great for cutting. They’re the 2003 Perennial Plant of the Year and are proving to be heat and drought tolerant. All they ask for is sunshine and a little deadheading.
Hardiness: USDA Hardiness Zones 4-9
Light: Full sun
Soil: Growth is optimum in moist, but well-drained soil
Bloom: June to September.
Another favorite that I’ve blogged about a couple of years ago is the Blackberry Lily or the Leopard Lily, a plant that is three plants in one.
1. In the spring, we are rewarded with blue green leaves than fan out in an attractive pattern much like an iris. Indeed it is a member of the iris family. Familiarly known as Belamcanda chinensis, after a DNA analysis, the new classification is Iris domestica.
2. In mid-July we are blessed with a multitude of small orange and red lily-like flowers, each blooming for a day then twisting like tiny wrung out rags before dropping from the plant. I’ve not read anything about the nectar of this flower but have observed a variety of insects actually competing over the sweet fluids.
3. In the late summer and fall and winter, the 3-lobed pods that are green and swelling now, split open to reveal the glossy fruit that resemble blackberries. These will fall from the plant and self seed or stems can be used for flower arrangements. I adore all three phases of this colorful summer perennial.
It will reproduce by seed and by rhizomes which may be divided and shared. Plant rhizomes under 1″ of soil and allow to dry between waterings.
Hardiness: USDA Hardiness Zones 5-10
Light: Full sun, partial sun, partial shade (I moved my plants from full sun to partial sun and they seem less stressed)
Soil: Well-drained; grows taller in fertile soil.
Bloom: July and August
