Once it gets into a lawn, English daisy, Bellis perennis, can be very difficult to get rid of without leaving bald spots. The thin but tough rhizomes creep along the ground, producing rounded leaves that get no longer than two inches. Mowers barely scratch the surface. English daisy seems to prefer partly shaded areas to drier sunny spots. Although invasive, it can be pretty in informal lawns.
The inch wide white flowers with yellow centers bloom in phases throughout the year. They are least abundant during cool winter weather, and most abundant about now, as weather gets warmer in spring. Garden varieties have more clumping growth, and slightly larger white, pink or rosy red flowers, all with yellow centers. Some have plumply double flowers. They are grown as flowering annuals, but can perform for a few years as light duty perennials.
Turf grasses are the ultimate in groundcover. They are very durable, and useful for covering large areas in a very user friendly manner. The toughest varieties are used for athletic fields because they withstand the wear and tear. In home gardens, all sorts of varieties are grown as lawns. Like other groundcovers, lawns limit erosion, and are cleaner than bare summer dust and winter mud.
My weekly gardening column does not have much space for everything that should be said about the various topics and featured specie. I just try to fit the most basic of information into the space available, but usually would like to fit more in.
Although a relatively small agave, the Queen Victoria agave, Agave victoriae-reginae, is also one of the most striking. Mature plants form dense foliar rosettes that are between only a foot, and a foot and a half tall and wide. What is so striking about them is the abundance of stout succulent leaves that can be so densely set that some older plants look like big, round and green pine cones.
Considering that some of the winter squash can last right through winter and into spring, there really is a squash for every season. By the time the last of the winter squash run out, the first of the summer squash will be ready later in spring. They get an early start here, and continue until frost. By that time, the earliest of the winter squash will be ready for autumn, and will last through winter.
We can keep this more brief than that long title.
Staghorn ferns are epiphytes. They cling to tree trunks, rocks or whatever they happen to grab onto. They can root into decayed wood if it is porous enough, but they are satisfied to just cling to the exterior. They do not need soil. They sort of make their own soil by collecting debris that falls from the canopies of trees above. In the jungles where they live, they get all the water they need from rain. They often live in the crotches of branches because that is where they happen to land. (The epiphyte I wrote about earlier was just a palm that landed in the wrong place, but is not really an epiphyte. 
Foliar tapestries are impressive in the right situation.
