It’s such a good thing that shopping centers and the like plant fibrous begonias and impatiens, in vast quantities, so you don’t have to. The Victorian gardening era in England produced some very inventive schemes for bedding plants. Beautifully designed and executed, they made use of annual plants of compact habit and low maintenance. Many of them were representational in their design-the most familiar of these would be the bedding plant clocks. Only rarely do I see bedding plants done to this level. There are those who plant oceans of uniformly growing fibrous begonias, impatiens, dusty miller and so on, without much in the way of interesting design-just lots of color. I like color as well as the next person, but I am glad this way of planting is being done by others, so I don’t have to.
I like annuals in the ground that mix shapes and colors in a dynamic, airy way. I like annuals in the ground that are unexpected. Some in ground annuals can be designed to give the impression of a perennial garden-with the added bonus of a very long season of bloom.
Big growing annuals are often passed by in garden centers, as they take time to get to blooming size, and do not show well in a cell pack, or 4” pot. Zinnias, cleome, cosmos, verbena bonariensis, and nicotiana alata varieties fall into this category.
But I find their old fashioned grace and size can make for a stunning annual display. Even shady annual areas can be enlivened by the addition of coleus, or tropicals; no shade garden is restricted to begonias and impatiens.
No doubt some very formal, and some contemporary annual plantings ask for a restricted plant palette, but I like to see this done on purpose.
If you garden is cottage-style, grasses, or the wispy textured verbena bonariensis added to the annual mix is charmingly meadow-like.
Grey plectranthus, the broad-leaved cirrus dusty miller, or chocolate sweet potato vine, grown in ground, is cool and contemporary looking.
Bold growing annuals in bold colors warm up, and loosen up a space. Zinnias, dahlias, green-eyed daisies, and giant marigolds read well from a distance. One of my favorite annuals, nicotiana mutabilis, is a cloud of white and pink when planted in masses; try interplanting a short growing annual to give color and interest at ground level.
There is another very good reason to plant mixed annual beds-the summer weather. Some years impatiens grows poorly. If that’s all you grow, it’s a poor year for your annual garden. If you have mixed in other annuals, perhaps not all is lost. A mix which highlights the color, textures, and volumes of annual plants will keep your interest over the course of the season. A mix of heights gives you color interest from top to bottom. Check out the annual flowers at your local nursery that are green right now, or unknown to you, or unusual to your eye; they may be promising additions to your summer annual garden.
If all the color of my past few posts has put you on overload, perhaps these pots will suit you better. As I have said, annual plants are those plants that survive but one season-this is a large group-some of which have no flowers of consequence.
Annual plantings or pots without flowers can be very effective and attractive. Some locations for annuals do not have enough sun to support good flower production. Annual plants can be as much about their forms, their leaves, and their architecture, as they are about flowers. This very tall “elegant feather” plant-no longer in production at Proven Winners, is a great foil for the round-leaved farfugiums. There are very few greens I do not like. My yews go black green in the winter when it is really cold, much like this Moses in the Cradle. The chartreuse and yellow coleus “Wild Lime” provides lots of punch in shade.
Chartreuse green is spring like, and fresh, no matter what time of year I see it.Grass after an electrical storm is so intensely dark gorgeous green-thus the term grass green. Lime creeping jenny is a versatile plant that highlights darker plants and obligingly trails. 
Green can be as much about texture and scale, as color. The slick, massive texture of this banana is complimented by the thick felted leaves of this variegated Plectranthus.
Caladiums, calocasias, and cannas have spectacularly large foliage. 
Calocasias and caladiums are thin-leaved (this refers to their “substance”); light will shine through them. Helicrysum both in lime and variegated leaf are densely felted. 
Phormiums, and dracaenas are stiff-strapped, and sword-like-an interesting contrast to this curly leaved farfugium. Cycads and escheverias have that dense waxy texture, and can be rounded, or spiky.
Tuscan blue kale has great size, a blistered leaf surface, and a very blue color-just the thing to pair with a blue juniper column, variegated licorice, and ornamental oregano “Kent Beauty” .
One of my favorite coleus is a yellow/olive color I call turtle green. The striped grass, miscanthus zebrina, is a happy companion to a plectranthus with the same color variation. The third element: the pairing of the plant material is complimented by the pairing of the pots close enough to encourage all the plectranthus to grow together.
So many beautiful greens. So many ways in which green is beautiful.
No matter that I have been planting annuals for the better part of 25 years; I have yet to get to that point where I have had enough. It’s a yearly conversation I have with myself, usually in late February. Do I still want to do this? Would I like some other career? Am I done with my career-would I just like a job? Another words, I am wringing my hands and fretting such, it would make you laugh.
Annual flowers on a terrace do a lot to warm up all the hard surfaces. I pay particular attention to the overall plant height and composition of those pots, as they are usually viewed up close, and while sitting.
