Today is Sweet Potato Day

Sweet potato

Today, Monday, April 6, is sweet potato day. I find this odd because here in Virginia, one does not plant or harvest sweet potatoes at this time. So I did some digging (no pun intended) and discovered the origins of the date.

In Benton, Kentucky, there is an annual sweet potato event the first weekend in April. Apparently, the sweet potato grows well in Kentucky’s hot, humid summers. Tater Days is celebrated with a parade, a carnival, and baking and canning contests.

Sweet potatoes are botanically different from white potatoes. Sweet potatoes (Ipomoea batatas) are in the morning glory family while white potatoes (Solanum tuberosum) are in the nightshade family. Both produce tubers but sweet potatoes are planted in the summer and harvested in the fall, while white potatoes are planted in the early spring and harvested in the summer. Sweet potatoes need a long growing season, at least 4 months, and thrive in Virginia summers, much like Kentucky.

While white potato plants are started with chunks of the tuber, sweet potatoes are grown from rooted sprouts called slips. Slips may look like limp, short stems with no roots. If you order slips, plant them when the soil has warmed to at least 60 degrees and night temperatures are above 60 degrees. If it is too cold, pot them up and hold them inside near a sunny window.

Plant slips about a foot part, covering with soil up until the first pair of leaves. These plants are usually grown in the ground, in loose, well-drained soil. These plants are vines that grow several feet long so give them plenty of space. The green, heart-shaped leaves are edible (deer like them too). The plants will grow up until frost and the tubers should be harvested before the first heavy frost. Southern Exposure Seed Exchange sells slips but try any company that specializes in vegetables.

You may see ornamental sweet potato plants for sale in small containers at the local garden centers. These are not grown to eat the tubers, they are grown for their beautiful foliage. Ornamental sweet potato plants can have chartreuse, dark purple, bronze-red, mahogany red, or variegated cream, green, and red colored leaves. These are used frequently in containers in public spaces and gardens because the vines are ideal “trailers,” draping over containers. Since they are tropical plants, they tolerate the summer’s heat and add quite a lot of color.

Try both, they will do well in your garden.

Salad Burnet Graces the Garden

Salad burnet (Sanguisorba minor) is a beautiful perennial plant that also serves as both a medicinal and culinary herb. This relatively small plant grows to about 6-8 inches tall and a foot wide. It stays green above ground for quite a long time, dies back in the winter, and re-appears in the spring. The plant grows in a clump or rosette formation. The small summer flowers are very small on wiry stems — barely noticeable.

As a medicinal herb, salad burnet has astringent qualities and is used to staunch bleeding. As a culinary herb, the leaves can be added to a green salad, egg salad, herbal vinegar, butter, cheese spread, or as “lettuce” with sandwiches. The foliage can be added to lemonade and is a popular garnish for gin and tonic cocktails. It has a clean green flavor, much like cucumbers.

The foliage has a delicate, lacy appearance. When my daughter and I made a charcuterie board for Thanksgiving, we decorated the board with salad burnet. We also used the green lacy leaves as a contrast to red cranberries and white mashed potatoes.charcuterie board

I have been growing salad burnet for years, but not necessarily the same one. It does self-seed a little, just enough for volunteers to show up in odd places. I dig them up and put them where I know they will thrive. Over the years, I have learned that salad burnet prefers moist areas, in full or partial sun, depending on the amount of soil moisture. I now have a plant growing next to my cutting celery and lovage, all of which are moisture lovers.

You are not likely to find the plant in local nurseries, but you can purchase seed from online seed companies. Start seed indoors in the spring, under lights, much like starting tomato seeds. You can direct sow in the summer, but my birds always steal my seed before they germinate. Or if you have a friend who has salad burnet growing in the garden, ask for a division in the spring. Try growing salad burnet for its many uses but also as a pretty plant in the garden.

Chives: Culinary Herb, Landscape Edible

Chives (Allium schoenoprasum) are a great addition to the garden, any garden, does not matter what is growing already, add chives. These perennial herbs are landscape edibles, they come back year after year, and can be tucked in between shrubs and flowers.

In my Virginia garden, my plants have already come back in March and I can’t wait to cut the leaves for scrambled eggs, chive butter, and mashed potatoes.

To keep up with my family’s demand for fresh chives, I have several plants. After I cut the leaves back on one, I leave that plant alone until it rejuvenates and then harvest the leaves of another plant. The pink, clover-like flowers appear in the summer.  Chive flowers are edible but do not eat them whole — pull apart the individual florets.

In the spring, I divide my current clumps to create more plants, both for the garden as well as for friends. Chives can be grown from seed but it may take a while for the plants to mature to harvest. It is best to buy a few small containers in the spring and tuck them in different places in the garden. These plants die back in the fall but emerge in early March. They can be lifted in March, divided, and re-planted or give away to friends. They prefer morning sun and afternoon shade and moist but well drained soil.

To make chive butter, simply let the butter come to room temperature, stir in chopped chives to taste, then refrigerate in a container. I use about 2 to 3 tablespoons of chopped fresh chives to one stick of butter. This can be done with soft cheeses as well. Chives can be preserved in the freezer or in ice cubes. Chives also can be used in herbal vinegars. Fresh minced chives add green to potatoes, soups, and rice dishes. Really, chives are so versatile in the kitchen and so easy to grow in the garden, there is no reason not to have them in your garden.

Salad Burnet: Lovely Medicinal, Culinary, and Decorative Herb

Salad burnet (Sanguisorba minor) is a medicinal and culinary herb and a beautiful ornamental plant. It is one of those pretty yet useful herbs in the garden. An herbaceous perennial, this relatively small plant grows to about a foot wide and one-half foot tall. It stays green above ground for quite a long time, dies back in the winter, and re-appears in the spring. The plant grows in a clump, in a rosette formation. The small summer flowers are very small on wiry stems — barely noticeable.

As a medicinal herb, salad burnet has astringent qualities and staunches bleeding. As a culinary herb, the young foliage is tastiest so pick from the center of the rosette and use leaves in a green salad, egg salad, herbal vinegar, butter, cheese spread, or as “lettuce” with sandwiches. The foliage can be added to lemonade and is a popular garnish for gin and tonic cocktails. It has a clean green flavor, much like cucumbers.

The foliage has a delicate, lacy appearance which makes it a great garnish. When my daughter and I made a charcuterie board for Thanksgiving, we decorated the board with stems. We also used the green lacy leaves as a contrast to red cranberries and white mashed potatoes.charcuterie board

Sweet Potato Twists

Sweet potatoes are botanically different from white potatoes. Sweet potatoes (Ipomoea batatas) are in the morning glory family while white potatoes (Solanum tuberosum) are in the nightshade family. Both produce tubers but sweet potatoes are planted in the summer and harvested in the fall, while white potatoes are planted in the early spring and harvested in the summer. Sweet potatoes need a long growing season, at least 4 months, and thrive in our hot and humid summers here in the DC metro area.

Ornamental sweet potato plants are grown for beautiful foliage in a wide range of colors. Ornamental sweet potato plants can have chartreuse, dark purple, bronze-red, mahogany red, or variegated cream, green, and red colored leaves. These are used frequently in containers in public spaces and gardens because the vines are ideal “trailers,” draping over containers. Since they are tropical plants, they tolerate our hot summers and add quite a lot of color. These are easy to find at local garden centers and are sold as small annuals in cell packs.

There is a relatively new line of sweet potato plants that have beautiful ornamental foliage (still edible) and produce tubers for harvest. Treasure Island Sweet Potatoes have been bred by Louisiana State University AgCenter from an original concept development and collaboration work by their partner FitzGerald Nurseries in Ireland. These plants can be grown in a container in the summer for colorful leaves and the tubers can be harvested in the fall. The plants in the Treasure Island series are named after different Polynesian Islands because each plant “hides” a treasure underneath the soil.

There are five plants:
Tahiti, green leaves and purple tubers
Tatakoto, dark green purple leaves and orange tubers
Makatea, golden green foliage and white tubers
Kaukura, purple foliage and orange tubers
Manihi, dark purple foliage and orange tubers.

These new plants would make an ideal children’s gardening project and vegetable container plant for those with limited space.

Either way you slice it, sweet potatoes are great additions for the garden. Try growing some this year!

Lovage: The Striking Edible Perennial

Years ago, I was interviewing a long-time member of my local herb club for our newsletter. I asked her what her favorite herb was and she replied, “lovage.” I was surprised, Lovage is hardly a popular herb in this country. But she explained that lovage had many uses in the kitchen and was a good salt substitute.  Ever since then I have been interested in growing and using lovage.

Walking Onions: Perennial Onion Plants for the Garden

walking onionWalking onions, also called Egyptian walking onions, tree onions, winter onions, and perennial onions, are very easy to grow.  Unlike an ordinary onion plant, Allium proliferum will produce little bulbs at the top of the plant in the summer. The weight of these marble-sized bulbils will pull the stem down, enabling the bulbils to root and produce a new plant. Although walking onions seem to walk by producing new plants a few inches away, they are not invasive. Continue reading
