Honeysuckle

Your question about is the a Lonicera spendida. What I see in the photo does not fit the description "the flowers in a terminal spike, springing directly from the uppermost pair of leaves", so I would vote no. I got it fromThe Dutch Plant Collection – climbing – Lonicera; http://www.lonicera.nl/lonicera-splendid... It has a good photo of the bloom spike and links to all kinds of Lonicera including the two I named earlier.

Lonicera has many varieties based on plants that come from Europe, Asia, etc. and those that have been hybridized for sale. Some are highly invasive, fragrance from very light to very heavy, colors and color combinations abound. The bloom can be open like this one or more closed and tubular, like the Texas native Lonicera sempervirens. Blooms can change color after pollination, white to yellow, as in Lonicera japonica. Leaves of Lonicera are opposite pairs as in your photo. Regions have Lonicera on native lists and on invasive list. Most are deciduous,but some are evergreen, depending on temperature zone. Lonicers can be a vine or a bush. There are just many kinds of Lonicera. I hope this help sort some of your questions. I am not familiar with this park, city, county, state? Depending on who manages the park there may be a groundskeeper that could answer which kind of honeysuckle. If not, try contacting the local native plant society or local collage with a Botany department.

Is it the evergreen kind then? Did I get the names right.

But it does not have a scent. Do some not have a sweet scent?

This is a honeysuckle, Lonicera sp.
