Are nasturtiums invasive?

Nasturtium has intensely colored flowers, with a spur on the back. In warm climates it blooms and seeds all year round, and is considered invasive in many of those areas. Trailing varieties look good cascading down walls.

Also, do nasturtiums spread?

Since it is considered an annual, plant the seeds in spring when the danger of frost has passed. Once they are established, nasturtiums will continue to spread and bloom until the first frost, with little more than the occasional sprinkling. Nasturtiums basically come in two forms: compact and trailing.

Subsequently, question is, do nasturtiums come back every year? Although most often grown as annuals, nasturtiums are, botanically, herbaceous perennials; that is, they die to the ground in fall and grow again the next spring. In frost-free areas such as coastal California, they grow like weeds, with 6-inch diameter leaves atop 20-foot-long stems sprawling year-round.

Additionally, are nasturtiums climbers?

Nasturtium plants are fully edible and growing nasturtiums can be used to lure aphids away from other plants in the garden. Nasturtium plants are easy to grow and may be climbing, cascading or bushy. Rich, fertile soil or too much fertilizer results in lush foliage growth and few nasturtium flowers.

Are nasturtiums good for the garden?

Plants that attract beneficial insects, repel pests, and otherwise increase crop productivity are called companion plants. Nasturtiums are a great companion plant for vegetables and roses. Nasturtiums are also a favorite of aphids and can be used as a sacrificial crop to protect more valuable plants.
