Nigella is more typically blue, but can alternatively bloom white, pink or lavender.
Those who crave blue for the garden probably know nigella, or ‘love-in-a-mist’, Nigella damascena. It blooms in May and June, typically with various shades of pastel blue, or can alternatively bloom pink, lavender or white. The lacy flowers are surrounded by lacier bracts, and suspended on thin stems among delicate pinnately lobed foliage, with very narrow (‘thread-like’) lobes. The plump brown seed capsules that appear over summer after bloom are commonly used as dried flowers. The plants can be half a foot to a foot and a half tall. Although annual, nigella self sows easily, so can grow in the same location for many years if allowed to.
Gardens might be colorful throughout the year here. There is not much time between the latest of the autumn flowers and the earliest of the spring flowers. Winter flowers are glad to compensate for the lapse. Of course, there are plenty of flowers in spring and summer. Nonetheless, dried flowers are more popular now that there are fewer flowers for cutting.
The quantity of flowers blooming within a particular season might not be proportionate to the quantity of flowers available for cutting. Flowers that bloom through winter, even if as abundant as spring or summer flowers, do not develop as fast. Harvesting too many bird of Paradise flowers depletes the limited supply before something else can replace them.
Deciduous foliage that provides spectacular color through autumn is no substitute for cut flowers. Nor is the majority of colorful bark that becomes more prominent through winter. Some colorful berries can function like cut flowers, but only if there are plenty to spare in the garden. Conventional dried flowers that grew last summer may be useful about now.
For the venturesome and resourceful, unconventional dried flowers and other dried plant parts can also be fun. Such items, unlike statice, straw flower, lavender and other familiar dried flowers, might be byproducts of gardening. They might be derived from detritus that should otherwise go to compost or greenwaste. Some might even be products of weeds!
Pampas grass, both garden varieties and the invasively naturalized type, produces bold blooms that dry quite well. Because the leaves can cause such nasty paper cuts, flowers might be easier to harvest from a distance, with a pole pruner. Hair spray can contain the fuzz, so that it does not disperse indoors. Cat tails, if still intact, are compatible with them.
Floral stems of lily of the Nile, New Zealand flax, and some species of Yucca are striking even after bloom. After deadheading, they can become flowerless dried flowers. Fruiting structures are no problem to remove. If within reach, some palms may provide distinctive bloom trusses. Floral design can be as imaginative as gardening and landscape design.
Statice is about as colorful dried as it is while fresh.
The papery flowers of annual statice, Limonium sinuatum, are so popular as seemingly synthetic dried flowers that many garden enthusiasts are surprised to find that they are happy to bloom naturally in home gardens. The clear shades of blue, purple, pink, orange, yellow and white seem to be dyed. The one or two foot tall flower stems are outfitted with odd papery ‘wings’ that make the stems seem wider than they actually are. Deeply lobed basal foliage forms shallow rosettes. Mature plants are about one or two feet tall, and a foot or so wide. Bloom begins late in summer, and continues into autumn. Good sun exposure and good drainage are preferred. Seed can be sown directly, or young plants can be added to the garden early in spring.
With proper processing, hydrangea bloom can be dried.
Statice, strawflower and globe thistle continue to bloom later than most other summer annuals, and hold their flowers longer. Even after bloom, the flowers are so stiff and ‘crispy’ that they remain intact and colorful until they succumb to exposure to weather. If cut and brought in from the weather soon enough, they will last as dried flowers at least until fresh flowers start to bloom in the garden next spring.
Strawflower and larger globe thistle tend to wilt and droop from the weight of the bulky flowers, so should be tied in small bunches and hung upside down to dry. Perennial statice (which has larger blooms than annual statice) tends to flop to the ground, but the stems often bend only at the base so that the rest of the stem length stays somewhat straight. Smaller globe thistle and annual statice often dry standing up while still out in the garden.
Yarrow and English lavender can be dried as well, but lose most of their color. Lavender dries naturally in the garden. Yarrow can likewise be allowed to dry in the garden, but probably keeps a bit more color if cut while still fresh and hung upside down. Because yarrow blooms are so wide, they should be hung individually or in small bundles. Queen Anne’s lace has even wider blooms that curl inward as they dry, so they really should be hung individually.
Old hydrangea flowers that are only beginning to fade can dry surprisingly well if cut and hung individually before they deteriorate too much or start to rot. Some varieties retain color better than others. Some fade almost completely to an appealing brown paper bag.
There are not many roses this time of year, but when they do bloom, even they can be cut and dried while beginning to unfurl. Only a few small and tightly budded roses can be dried when completely open. Because they droop right below the blooms, roses should be hung upside down to dry. Dark colored roses get very dark as they dry. White roses turn tan. Pink and yellow are probably the better colors.
Cat-tails and pampas grass flowers are big, bold and dated cut flowers. Yet, for situations where big flowers fit, they are just as practical now as they were in the 1970s. Because pampas grass flowers shed, and cat-tails can explode (to disperse their seed), they should be sprayed with hair spray or another fixative to keep them contained. Pampas grass foliage has dangerously serrate edges that can give nasty paper cuts, so should be handled carefully, and displayed out of the way.
