Daylily

Each flower lasts about a day.

Each flower lasts for only a day. That is why the common name of Hemerocallis is simply daylily. Each floral stalk provides several flowers that bloom continually for several days. As one flower deteriorates, another replaces it. Because floral stalks shed so continually, they are not very practical as cut flowers. They are splendidly colorful in gardens though.

Most popular daylily cultivars are products of breeding that is too extensive to document. That is why almost all lack species names. Their cultivars names generally suffice. Most daylilies bloom for a month or so. Also, most bloom best for early summer. A few bloom a bit earlier. Some bloom as late as autumn. Some can bloom randomly or twice annually.

Daylily bloom can be yellow, orange, red, pink, almost purplish or combinations of these. Yellow or pink can be so pale that it seems to be almost white. Flowers can stand as tall as three feet, on bare stem. Their arching grassy foliage stays somewhat lower, in dense mounds. Most cultivars are evergreen. Some are deciduous. They propagate by division. Some migrate by vigorous stolons.

Lily Of The Nile

Blue fireworks bloom for Independence Day.

The Nile River Valley is a region of extremes. It floods at times, but is hot and dry at other times. Lily of the Nile, Agapanthus orientalis, naturally survives it all. It can easily survive here. However, it survives arid heat by shedding a bit of foliage. Therefore, it is generally healthier here with at least occasional watering through the warmest weather of summer.

The almost spherical floral umbels of lily of the Nile explode into bloom like blue or white fireworks, just in time for Independence Day. They are about six to eight inches wide, on elegantly bare and slightly leaning stalks that stand about four feet tall. Individual flowers are only about an inch or two long. Flowers bloom only once annually, but last for weeks.

With or without bloom, the dense and evergreen foliage of lily of Nile is always lush. The soft and strap shaped leaves are about a foot and a half long, and flare outward from low basal rosettes. New foliage obscures deteriorated old foliage. Fleshy roots firmly secure plump rhizomes. Division relieves crowded rhizomes, and contains their slow migration.

Saint John’s Wort

Saint John’s wort blooms somewhat late.

Although it shares the same common name, Hypericum beanii is not the same sprawling Saint John’s wort that is now so aggressively naturalized within some local ecosystems. It is shrubbier and much more docile. Mature specimens get no more than three feet high and wide. It should be evergreen here, but can get sparse through cooler winter weather.

Bloom begins in the middle of summer and continues at least to early autumn. Cheerfully bright yellow flowers are two inches wide, with five rounded petals around fuzzy centers. The light green and oblong leaves are about two inches long. Stems are rather wiry, and can eventually get shabby. Coppicing as winter ends stimulates fresher vigorous growth.

Saint John’s wort prefers sunny and warm exposure. It is otherwise not very demanding. Regular watering enhances bloom. Yet, established plants can survive without watering. Where coppicing (cutting back to the ground) in late winter is not a problem, Saint John’s wort performs well as a low hedge, or unshorn border. Frequent shearing inhibits bloom. Rust is a potentially bothersome fungal disease.

Black-Eyed Susan

Black-eyed Susan epitomizes prairie style.

A flower that is so prominent in American culture should have a more appealing name than black-eyed Susan. Even the Latin name, Rudbeckia hirta, sounds bad. Is Becky really so rude? Did she hirt Susan? Well, black-eyed Susan is good enough to be the state flower of Maryland, and is one of the most popular of flowers for prairie style gardens of the Midwest. After all, it naturally grows wild in every state east of Colorado. Here in the West, it is a light-duty perennial that is more often grown as an annual. As a cut flower, it can last more than a week.

In the wild, the three inch wide flowers of black-eyed Susan are rich yellow with dark brown centers, and can stand as high as three feet. The typically smaller but more abundant flowers of modern varieties can be orange, red or brownish orange, on more compact stems. Gloriosa daisies are fancier cultivars, with larger flowers that are often fluffier (double) or patterned with a second color. Individual plants do not get much wider than a foot, with most of their rather raspy foliage close to the ground. All black-eyed Susans bloom late in summer or early in autumn.

Rockrose

Harsh exposure is fine for rockrose.

The few rudimentary rockroses that were available years ago have been bred into too many cultivars to keep up with. Some of the traditional types can get a few feet tall, with delightfully irregular growth, and flowers that are almost three inches wide. Most of the modern types are relatively dense, low and mounding, like a deep ground cover, with smaller but more profuse flowers. Most bloom pink. Some bloom white. After the initial spring bloom phase, a few flowers continue to bloom sporadically through summer. The grayish and aromatic foliage is not as impressive as the bloom. Rockroses want well drained soil and good warm exposure.

Cecile Brunner Rose

Cecile Brunner rose is elegantly simple.

Few modern rose cultivars are as tolerant of neglect as Cecile Brunner rose. Furthermore, few recover as efficiently from renovation after many years of neglect. Old overgrown thicket growth that might be unsightly while bare through winter can be spectacular in bloom. Alternatively, it does not mind aggressive pruning, even if only stumps remain. It easily regenerates with fresh new canes.

Bloom is nicely profuse early in summer. The individual fluffy pink flowers are not much more than two inches wide, but are rarely alone. They develop in big and possibly billowy clusters. The faint fragrance is easy to ignore, but appealing to some. After primary bloom, subsequent bloom is sporadic. Green stems are less prickly than stems of most other roses. Foliage is rather light green.

Shrubs are vigorous but compact. They may not get much taller than two feet. Most stay less than four feet tall. However, there are actually a few cultivars that are known as ‘Cecile Brunner’. Those that are most familiar are climbing types that can easily get higher than twenty feet. Their bloom is sparse after profuse early summer bloom. Some might bloom rather profusely again for autumn.

Summer Flowers Make The Cut

50819thumb
Try something new for cut flowers.

It would seem obvious that there would be more flowers to cut to bring into the home during summer than there would be in winter. A quick tour through the garden might prove otherwise. Much of the color in the garden this late in summer is provided by flowers that fade quickly, or small flowers of shrubby plants that lack good stems for cutting.

Lilies, gladiolus and most of the lily of the Nile that bloomed earlier in summer are finished. Bearded iris (reblooming types) that will soon be blooming again, as well as cannas, wilt too much to last long as cut flowers. Dahlias happen to be at their prime, and are excellent cut flowers if their water gets changed regularly. Otherwise, they rot and smell badly.

Realistically, anything that blooms is fair game. Of course, this does not mean that everything tried will work. It does means that some flowers that are not often thought of as good cut flowers might be worth considering as such. Not all of us are equipped with roses, zinnias, dahlias, sunflowers, delphiniums, blanket flowers or the many other favorite summer bloomers.

All sorts of sages, which are also known by their Latin name of ‘salvia’, are delightful cut flowers. However, some types are not very showy. Others wilt right after getting cut. Mexican blue sage may or may not wilt, but is colorful enough to be appealing even if it can not stand up like it should. Sometimes it is best to try something new to see if it works.

Sea foam statice and annual statice are nice cut flowers both fresh and dried. Fresh flowers are probably more colorful, but of course, do not last as long as dried flowers. Annual statice is lightweight enough to stand upright as it dries in a vase. Sea foam statice has bulkier flowers that should probably be hung up-side-down to dry straight.

Oleander certainly is reliably colorful, but is not worth cutting. It wilts almost immediately, and drips toxic sap. However, the stigmatized and common lemon bottlebrush is a surprisingly tasteful cut flower with rustically aromatic foliage. Speaking of foliage, some types of eucalyptus, particularly the red flowering gum (Eucalyptus ficifolia), have handsome flowers as well.
