These tend to grow fine in USDA zones 7 to 9. Mixed breed verbenas, or hybrids, are really tough plants in USDA zones 8 to 11. But, you can grow them as annuals in any zone. <\/p>\n\n\n\n

Verbena is usually a short plant that grows out rather than up. It has dark green leaves with edges that look like they have teeth. It produces groups of colorful flowers from spring until fall that will make any gardener happy.<\/p>\n\n\n\n

How to Grow Verbena Rigida<\/h2>\n\n\n\n

Growing Verbena rigida<\/em> is pretty straightforward. These plants like lots of sun, and a soil that drains water well. They don't do well if the soil is too crowded or soggy, as they can get root rot.<\/p>\n\n\n\n

Make sure to give your plants enough room to grow, so that air can move around them. The exact space you need depends on the type of you are growing. Cut the plants back once or twice a year to encourage them to grow, and to produce more flowers.<\/p>\n\n\n\n

Avoid planting in shady areas, as this slows down growth and flowering. These plants require at least six hours of sunlight each day, witheight to ten hours being even better for blooming.<\/p>\n\n\n\n

Verbena rigida<\/em> plants prefer a loamy soil with a pH balance of between 5.8 and 7.2. That said, they are not too picky about soil pH level, so as long as it drains water well. They do not do well in clay-like soil, as this retains waterand can lead to root rot.<\/p>\n\n\n\n

Water your Verbena rigida<\/em> to keep it moist until it has settled into your garden.<\/p>\n\n\n\n

Once your plants have matured, they typically need about one to two inches of water per week. They can readily handle a few weeks without water if conditions are dry. Over watering can lead to botrytis blight, whilst under-watering may result in attracting spider mites.<\/p>\n\n\n\n

If you plant Verbena rigida<\/em> as an annual, it will do well in most climates, but it might struggle in the very hot parts of summer. <\/p>\n\n\n\n

When grown as perennials in zones 8 to 11, hybrid verbenas are sturdy. They do not need lots of food, but they do enjoy a bit of slow-release, balanced fertilizer to help them flower better.<\/p>\n\n\n\n
