Can you please tell me if wildflower seeds come up each year?
In terms of wildflower mix coming up each year, this does depend on whether the flowers are annuals (plants that only last a growing season) or perennials (plants that live more than one growing season - up to three years or more). Typically wildflower seed mix packets are usually perennials, but some can be a mixture of both. This autumn when flowers have finished and seeds are developing on your perennial wildflowers, you can harvest the seed (keeping them in a dry place over winter), before sowing again in spring. Alternatively, you can let nature take its course with seeds dropping around the existing plants and remaining dormant over winter before sprouting in spring. If you purchase a good seed mix they should come up each year.
