Wisteria is perhaps my favorite flower. It is intoxicating.
Raised in the South, I always marveled at the free-growing version of wisteria, like above. It was essentially considered a weed, but wisteria beat kudzu hands down! Lavender blossoms with deep purple accents would drown wooded patches along the rural highways.
I remember about 15 years ago seeing my first wisteria bush in someone's yard. I thought "Hurrah for wisteria" with its new status as a desired plant. Only since then have I seen beautiful arbors and pergolas of it. Cultivation also brought the white variety; in fact, the cultivated purple is different and darker than the wild. However, its smell is as sweet as honeysuckle and it makes bumble bees quite happy.
