10 Bonny Blue Plants and Flowers

Fragrant hyacinths make great partners for spring daffodils, needing little more than full sun and well-drained soil mixed with plenty of organic matter. Hardy in USDA Hardiness Zones 4-8, hyacinths may produce fewer flowers after their first year in the garden, so some gardeners treat them as annuals. Look for varieties that range from 6-12” tall.

Charming forget-me-nots (Myosotis) grow happily in partial shade in the damp soil around ponds or streams. They’re typically winter hardy in Zones 3-8, but check the tag or label on your variety to be sure. If they do come back in your garden, they usually flower and die in their second year--but don't worry. They re-seed freely. Some grow just 6-8” tall while others may reach 24”. This variety is 'Mon Amie.'

Hydrangea colors are affected by the pH of your soil, and if you have acidic soil, and aluminum is available to your plants, Cityline Mars will produce blue flowers. Not sure about your planting site? If you want blue blooms, a pH test will help you determine whether to amend the soil with aluminum sulfate. This bigleaf hydrangea prefers part sun to sun. Hydrangeas differ in hardiness and size (some grow to 20’ tall). This variety matures at 12-36” and is hardy in Zones 5-9.

Spikes of bright blue flowers make ‘Guardian Blue’ delphiniums a stand-out in your garden. The stems are thick enough to snip for bouquets, and with a bit of luck, the plants will rebloom. You can find delphiniums in a range of sizes, from about 18" tall to 6' and over. Give these butterfly and hummingbird magnets full sun. Most are hardy in Zones 3-7.
