5 fragrant plants for your hot garden

Summer is coming and with it, warm evenings to enjoy outside on a patio beneath stars and moon — and all of Elon Musk’s orbiting satellites.

While star-watching and satellite-watching may appeal to the eyes, fragrant plants in your garden create appealing scents that makes being outdoors after dark an even better experience.

So here are 5 very fragrant trees, shrubs, and vines that do well in hot, dry climates. Note that not all are drought tolerant. Some will need watering as the days heat up. And some bloom and release their fragrance during the day, too.

Fast growing and fragrant

Butterfly Bush or Summer Lilac (Buddleja davidii). This rangy shrub, above, grows fast and produces fragrant, lilac-like blooms in mid-summer. In cold winter areas it may freeze to the ground, but will regrow and bloom the same year. In fact, if you plant one now, you may have a good-size shrub with blooms this summer in your desert garden. One interesting variety is the ‘Harlequin” with dark magenta flowers and white-edged leaves. Another popular variety also created by Monrovia Nursery is the “Black Knight,” pictured above.

A show-stopper in your front yard

Flowering Crabapple. (Malus ionsis ‘Klehms’) Cars will come to a screeching halt on the street outside your home if you plant a flowering crabapple in your front yard. When this tree blooms, it is covered with glorious, fragrant double-pink flowers. The blooming period is short and the resulting fruit is best in jellies or pickled. In the fall the leaves turn a brilliant rusty orange giving you a second season of color.

Like most crabapple trees, it is rounded and low-growing to about 15 or 20 feet and definitely needs regular irrigation during hot summer months. Because some varieties are susceptible to regional diseases, ask your local nursery which one is best for your area. But try to find a fragrant, double-flowering one!

Imitating orange blossoms

Pittosporum (Pittosporum tobira) is also called ‘Mock Orange’ because its fragrance can envelope a garden in an unforgettable scent similar to a true orange. Over the years pittosporum has become quite popular with commercial landscapers because two dwarf varieties are definitely drought tolerant: ‘Wheeler’s Dwarf” or “Turner’s Variegated Dwarf’. They are almost indestructible.

But neither of these dwarf hybrids produce the incredible fragrant flower clusters that the non-dwarf Pittosporum tobira does. It can be used as a hedge shrub or small tree and grows from 6 to 15 feet tall with very dense shade beneath.

Another member of this family is the Cape Pittosporum (P. viridiflorum) which grows to 25 feet high, has small, very fragrant flowers, but–alas–may not be suitable for all hot gardens. It does better in more humid, tropical climates. Again, ask your local nursery.

A true night bloomer

It’s commonly called “night-blooming jasmine”. It is, however, not a true jasmine at all, but is a jessamine plant (Cestrum nocturnum), a member of the nightshade family along with tomatoes and peppers. Whatever its name it is noted for releasing its fragrance after dark in hot, dry gardens.

Like jasmine, jessamine plants can be shrubs or vines. Night-blooming jessamine is a tropical, evergreen shrub, native to the West Indies that grows 8-10 feet (2.5-3 m.) tall and 3 feet (91.5 cm.) wide. It is evergreen and tall so it makes night-blooming jasmine an excellent candidate for privacy hedges and screens. It bears clusters of small, white-green flowers from spring through late summer. When the flowers fade, white berries form and attract a variety of birds to the garden. These berries are toxic. Do not eat them.

Decades of graceful purple blooms

The lovely Wisteria (sinensis) is a surprisingly tough vine suitable for growing in hot dry climates. Better yet, it does well in poor soil so, if you plant one, do not fertilize it. Wisteria requires patience because it may take up to 5 years for the first flowers to bloom if you have planted one grown from cuttings. Wisteria grown from seed may take 20 years to bloom. Then it is non-stop! After that it could continue to put forth fragrant flowers for decades. In Sierra Madre California the annual Wisteria Festival celebrates one plant that is documented to be over 100 years old. And still blooming!

I had considered adding Hall’s Honeysuckle (Lonicera japonica ‘Halliana’) to this list because it is so very fragrant, but even in hot dry climates is is highly invasive.  Like Cat’s Claw (Macfadyena unguis-cati) it will take over wherever it’s planted.
