They said it couldn’t be done, but finally, there’s a new kind of lavender that looks good all winter. Appropriately dubbed ‘Phenomenal’, it’s so good, in fact, that it’s now being used for municipal plantings. To understand the hype, I bought three plants last year to carry out a trial run. What I discovered was nothing short of, well, phenomenal.
A NEW DAY FOR LAVENDER
Who doesn’t love what’s exciting and new? This variety checks all the right boxes. Exceptionally tolerant of both hot and cold weather, Phenomenal lavender is built to withstand nature’s trials. Not only does it retain its foliage through the winter, but it also stands up to humidity. And that’s no small feat for a species that originated in the dry, hot climates of Africa, Europe and Asia.
But wait – there’s more! Phenomenal’s wands of deep purple flowers are highly fragrant, which according to its breeders, is due to the plant’s high oil content. Moreover, the flowers are darker than most traditional lavenders and they last longer; blooming from mid-summer all the way until fall.

But for me, Phenomenal’s strongest appeal lies in its hardiness. The plant looks amazing in winter, maintaining its silver-grey foliage atop a neat, compact mound. Here in Maryland it’s the beginning of February and, as you can see, my plants are still holding their own.

HEDGING YOUR BETS
So why is Phenomenal lavender being used in municipal plantings? First, because it requires little to no maintenance. Since it naturally forms round, bushy mounds, it seldom needs pruning. And in all but the coldest climates, its drought-tolerant foliage stays thick and green all year round.
Second, this variety is the ideal size. Topping out at around 24 inches with a spread of just under four feet, it’s the perfect plant for hedging. Now, thanks to Phenomenal, we Americans can grow the classic, purple hedgerows that so remind us of France. And who doesn’t yearn for a taste of Provence?

A PHENOMENALLY DRY SENSE OF HUMOR
These days, lavender is commonplace in most American gardens. Yet, I often find it planted in all the wrong places, in particular part-shade. All lavender varieties, including Phenomenal, need full sun to thrive. That means 6 hours or more of direct sunlight a day.
Regardless of the variety, if your plant is located in part shade (or worse, shade), it isn’t happy. Consider transplanting it to an area of the garden where it can sunbathe daily. This will not only help it maintain its shape, but also ensure it produces masses of purple flowers for you to enjoy throughout the growing season.

Once established, Phenomenal lavender (like all lavenders) is drought-tolerant. Surprisingly, it performs best in dry to medium, even poor, light soils. However, excellent drainage and good air circulation are key.
Most importantly, since lavender likes things dry, you should go easy on the mulch (whose job is to retain moisture.) Keep it away from the base of the plant, or better yet, consider mulches like ground shells or white gravel to reflect light back onto the plant and to allow for better drainage.
