(1992) This plant is likely mislabelled, from the Kellam collection. (1992) From the planting in 1992, it grew tall and small-leaved (like an lepidote rhodo). The label said it was a dwarf white Cowles selection. It was cutback in 2016, and is located beside the trail, near the intersection with the Kellam Spur Trail.

(Unknown date) An older rhodo located next to the large 'Cynthia' rhodo.

(Before 1980) A very old, tall plant, widely planted in the early years of the Glen, with pale lilac flowers with a white center. It is located on the trail, just north of the intersection with the Kellam Spur Trail.

(1996) From Sandwich, MA acquired by TLM. Raised by Dr. John Wister at Swarthmore College. Located just off the trail near the intersection with the Kellam Spur Trail.

(Before 1980) One of a group of three plants, probably layered from one plant. A hybrid with one parent being 'Purple Splendour', giving the flowers a purplish-red color. The plant is quite common in the Glen and distinguished by the unusual shape of the flower buds. It is located on the trail at the intersection of the Kellam Spur Trail.

(Unknown date) An older, spreading plant located west of the large colonizing 'Cynthia' rhodo on the Short Branch Spur Trail. Hybridized using R.catawbiense by Waterer before 1900. Has lilac-pink flowers.

(Unknown date) A very large, spreading plant located near the intersection of the Short Branch Trail and the Short Branch Spur Trail. The Cynthia hybrid is probably the most vigorous rhodo growing in the Glen.

(Unknown date) A Dexter hybrid located at the intersection of the Short Branch Spur and Kellam Spur trails. (1993) It was not thriving in 2016, probably due to encroachment from another rhodo.
