Does that mean sun for every second the sun is up or does it mean a minimum
amount of sunlight hours?

I just bought a nice Dropmore Scarlett Honeysuckle vine and I want to make
sure I'm planting it in the best spot I can find. If I put it near my patio
(where I would like it to grow on the railings so I can see the hummingbirds
visit) it will get sun for about 10 or 11 hours a day but shade will fall
over it around 6pm until sundown. Is that adequate for optimum growth?

Thx,
Giselle
