Can anyone recommend a showy vine with fragrance to substitute for Wisteria?
Criteria looking for with the vine is one not plagued with a lot of insect pest or disease problems, not requiring high maintenance (limited to 1-2 pruning sessions a year, fertilizing), will go up and over a pergola, strikingly showy for at least one season (a plus if showy additional seasons), not an eyesore at any time of the year. Not invasive. Attractive fragrance preferable.
Cultural conditions of the site are Zone 9a, full sun, alkaline high PH soil. Soil thin 2" topsoil layer over compacted limerock, will be bermed with quality topsoil and composts. Planting site readily drains from rain event but 15' away from edge of freshwater river canal. Planting site does sit several feet higher than water level. This vine will be going into a Japanese Garden.
Can anyone think of a vine that meets the above? Thank you all in advance for the help!
