These garden staples are often associated with <a href=\"https:\/\/www.botanicalinterests.com\/community\/blog\/seeds-cottagecore-garden\/\">cottage gardens<\/a> or traditional English designs,<strong> bringing charm and color <\/strong>season after season. Many are also easy to grow from seed, letting you fill your garden quickly without spending too much money.<\/p>\n\n\n\n<p>March is the perfect time to start many of these classics from seed. Some perform better sown in trays indoors, while others prefer direct sowing and hate being transplanted.

In warmer climates (USDA zones 7 and above), wait until one to two weeks after the last frost.
