is it blooming now? could be lonicera fragrantissima or winter honeysuckle. it grows as a shrub (semi-deciduous in my area) rather than a vine and blooms during winter with whitish flowers that have a strong lemon fragrance. the fragrance can carry a good distance from the shrub on a warm day. they have been blooming here for about 4 or 5 weeks. |
