Three Heat-Tolerant, Pollinator-Attracting, Deer-Resistant Perennials

We are having a hot, dry streak now which really separates the weak from the strong in the garden. Now is a good time to see which plant is tolerating this weather well in other people’s garden so you can copy for your own garden.

On one particularly hot day this past weekend I was downtown visiting the Smithsonian museums. I spent a lot time in the Pollinator Garden, next to the National Museum of Natural History. This is a 400 x 40 feet area on the east side of the museum at 9th Street between Constitution Avenue and the Mall. The Pollinator Garden is managed by Smithsonian Gardens staff and is a wonderful place to relax and watch the butterflies.

I noticed several plants that were tolerating the heat well, that is, they were in full sun and not covered in powdery mildew.  As expected, they were definitely attracting bees and butterflies. These seemed worthy of copying in my garden. When I got home I looked them up and learned that they are rabbit and deer resistant as well as being full sun, drought-tolerant perennials. This is not to say there weren’t other worthy notables in the Pollinator Garden but these are definitely plants to add to my collection next year!

Wild Petunia

Although this plant is called wild petunia (Ruellia numilis), it is not related to petunias. These plants have lavender blue flowers that bloom from summer to fall. They are low growing with a trailing habit, reaching about a foot tall. They can serve as a groundcover and be used as a spiller in a container.

Allium ‘Millenium’

‘Millenium’ is a member of the onion family (Allium) grown for its ornamental, purple globe flowers. The plants grow to 1 to 1 ½ feet tall, providing a strong vertical interest.  They are great in the garden and can be used in containers as thrillers. After the flowers fade and die, the globe structure becomes tan and remains for a while, which also provides interest.

Walker’s Low catmint (Nepeta) is a member of the mint family, so it has gray green aromatic foliage. In the summer, the plant has small, lavender blue flowers, but each stalk has so many that sometimes the plant seems covered in a purple haze. The plants are low growing, about a 1 to 2 feet tall, and used as a groundcover or small shrub.

Local Resource for Growing Tomatoes Successfully This Summer

year-of-the-tomato-logoThe University of Maryland Extension (UME) has a fantastic “Grow It Eat It” program. This year, they have declared 2016 as the Year of the Tomato. To celebrate this popular veggie, they created a site devoted to learning more about growing, harvesting, and preserving/canning tomatoes, http://extension.umd.edu/growit/2016-year-tomato. The site has a variety of resources: a list of local UME offices, contact information for Maryland’s gardening experts, and the list of the Master Gardener plant clinics for getting answers to tomato problems. It also has a link to their Youtube playlist of tomato information; recommended cultivars; winners of the 2015 tomato tasting events; and tomato-related articles on the Grow It Eat It blog. Although this is a UME resource, the information is applicable to those of us who live in the Mid-Atlantic area so Virginia and DC residents can enjoy the bounty. If you ever wanted to grow tomatoes successfully, now is the time!
