Planting annuals in your Houston landscape

Planting annuals in your Houston landscape is a visual treat, the “fresh air” that a landscape design regularly needs. With each new season, they give you and all who travel past your property a renewed appreciation of the exterior landscapes. Annuals put color, texture and liveliness in your gardens. Purple pansies, orange daisies, pink begonias and red geraniums delight and captivate us when used as seasonal color because the human eye is naturally drawn to what is new.

Exterior Worlds uses the basic design philosophies of unity, repetition and balance when planting annuals, principles that are foundational to planting gardens of all types, shapes and sizes. There are many ways we accomplish these goals:

• We limit the color choices to those that work well together.
• Sometimes we may plant a single specimen throughout the gardens.
• Conversely, we may repeat a color across several different plant types.
• Always we consider the whole so that the overall scheme stays in balance.

Garden pots, containers and urns are perfect vessels for your seasonal color. For instance, potted annuals make a courtyard garden design really come alive. They add an architectural element to the ambiance. We have used a combination of pots and color to define a garden space or frame a view. By planting annuals in large-sized containers overflowing with color, we have also used them to create a zone, and, when you tire of that arrangement, we can always reconfigure the pots into another design.

We also recommend that you supplement the color that annuals bring to your yard with blooming trees, bushes, vines, grasses and other plant material. We like to mix up the blooming phases of your choices so that you get different spots of color throughout the year. For instance, native grasses provide movement and subtlety. We also use colorful, variegated foliage and berry-bearing bushes to bring variety without extra expense. In particular, planting roses is a prized way to add exquisite color to your gardens.

One note to the wise gardener: installing a drip irrigation system is a smart way to deliver water to your annuals, especially if they are in small or difficult spaces. Examples for their uses include beds between sidewalks or along a driveway, rose gardens, and containers such as decorative pots and hanging baskets. Drip systems let you to water the root systems instead of the flowers, something your annuals will truly appreciate.

When to plant annuals is a question we get a lot. The first consideration needs to be which annuals are appropriate for the current season, and by that we mean specifically the Houston climate. Attention must be paid to our mild winters, hot and humid summers and tendencies toward monsoon-like rains. The same answer is true for the question when to switch out to next seasonal color. In general, you’ve most likely waited too late if the current plantings aren’t surviving.

Make your Houston home and garden pop by planting annuals. In yards of all sizes, in garden beds, in wall planters, in pots, on patios, near the pool and spa, and at entryways—seasonal color breathes fresh life into your landscape design.
