South Carolina Native Plant Society • Summer 2010 5 Spring Seed Collection Field trip Ann Barklow, Garden Magic Company

In early June I joined a group of 10 SCNPS members for seed collecting of natives along upstate South Caro- lina roadsides. Having recently relocated to Greenwood, SC from Manhattan Beach, CA, this was my second outing with the group. My first was in the winter at Twin Chimneys landfill where we rescued native plants in 27oF weather. The seed collecting trip was a humid 90 degree day. Coming from a city where the temperature high is 78 and low is 50, I promised myself I wouldn’t whine. Figure 1.

Photo courtesy of Janie Marlow, www.namethatplant.net I don’t think I will ever take for granted here. Being a landscaper and horticulturist I have two criteria when I volunteer for plant societies. I have to learn something and have fun. I came away with both thanks to “foreman” and leader Bill Stringer from Clemson University and the great group of members who came to work. At our first stop I watched my companions spray their socks and the bottom of their pants with DEET for tick and chigger prevention.

We were shown Lespedeza hirta which we learned to identify because of the trifoliate leaves and stipules that we inspected with our hand lenses. Nearby were several Silphium compositum or Kidney-Leaf Rosinweed (Fig. 1). These large basal rosettes of leaves in the Aster family Figure 2. Flowering kidney-leaf rosinweed. Photo courtesy of Janie Marlow, www.namethatplant.net were hard to miss along the roadside. The summer bloom promises to be showy yellow daisies on an impressively tall spike (Fig 2). A perennial herb, also in the Aster family, Liatris squarrosa, was briefly removed from the soil so we could examine the underground globose stock where the plant stores its reserves for the following season. We saw sassafras, the flavor source for root beer. Sassafras albidum, an aromatic shrub to small tree has a distinctive quality of having one or sometimes two lateral lobes on its leaves. I placed stars next to my favorite plants. They made this list because they were neat in appearance and I often think of plant combinations that will look good together in a more structured garden landscape. Ruellia carolinensis, Wild Petunia (Fig. 3), with its purple flowers (no relation to petunias), was a pretty sight, along with Stylosanthes Figure 3. Wild petunia, Ruellia carolinensis.
