On February 22, 2018, we monitored our team's five multiflora rose (Rosa multiflora) shrubs at our Radford Bike Path site in Radford, Virginia. It was a very warm, sunny day (78°F). As with last week, temperatures have continued to be higher than normal with temperatures exceeding 80°F. Since last weeks monitoring there has been only slight changes to each of the five plants. Each shrub has seen a slight increase in the number of breaking leaf buds but are still within the same window as last week (101-1,000). Few leaves (>5% Total Canopy) were seen on all five plants. Of the leaves present, most are continuing to increasing in size, and on average they are at 25% of their potential size. As with last week, two of our plants continue to bear ripe fruit. (Post by T.

On February 18, 2018, I monitored our team's five multiflora rose (Rosa multiflora) shrubs at our Radford Bike Path site in Radford, Virginia. It was a warm, sunny day (55°F) following an unusually warm week where temperatures rose above 65°F and rain persisted much of the week. Since last weeks monitoring, I have notice that many of the understory plants are beginning to leaf out and develop some color. On the multiflora rose shrubs, I noticed that the leaves have a red outline at the end of each leaflet. On all five of our shrubs, I estimated more than 100 breaking leaf buds on each shrub. Additionally, two of our shrubs were bearing ripe fruit that was not present the week prior. When ripe, the fruit are red, fleshy, and about the size of a pea. (Post by C Gleason.)
On February 8, 2016, we hiked down to the a strip of forest edge habitat alongside the New River and Radford Bike Path in Radford, Virginia. It was a cool, sunny day (42°F). Our team choose five different Multiflora Rose (Rosa multiflora) shrubs to study over the course of the semester. Once each team member had chosen a shrub, we attached to each rose bush both a marked piece of pink ribbon and a metal tag providing the identity of each individual shrub. On all five bushes, we noticed leaves that appeared to still be growing in size (<25% of full size). On one of our shrubs in a particularly shady spot had no breaking leaf buds compared to the other four shrubs that had few breaking leaf buds (3-10). Leaf buds are considered "breaking" when the green tip of the leaf is visible at the end of the bud. Across all shrubs we still don't have any evidence of flower buds, open flowers, or fruit.
