Planning a Spring Flower Garden? Here's What to Plant
Spring is here! Frogs are croaking, birds are singing and flowers are blooming. Whether you’re getting
ready to sell your home or just want to add some beauty as an investment in your home (and equity), this guide will help you get started.
Plant Hardiness Zones
Before you plant anything, it’s important to know what grows well in your area and when to start planting certain varieties. The USDA divides the US into 13 zones. Other organizations use seven to eight zones and are easier to understand. Zones are based on a ten degree difference in average yearly winter temperature and are basic guidelines for what to plant if you want plants to thrive in your area.
How to Plant for Maximum Beauty
Making a flower bed look professional is easy if you remember to add varying color, height and textures. For each zone below, we’ll give some examples of flowers to plant in the back, middle, front and a variety filler that meets these rules.
Zones 3 and 4
These zones represent the coldest zones in the US, and the shortest growing season, with annual minimum temperatures of -30ºF to -20ºF. Planting in this zone is between April and September.
Consider these flowers:
Back: Hollyhock – The attractive colors, ranging from red, orange, yellow, black, purple and pink—and the plant’s height make it a garden favorite. Some varieties reach five to six feet.
Middle: Monkshood—These popular and beautiful ornamental flowers bloom white or blue, but gardeners should take note: the flowers are poisonous if ingested.
Front: Hippeastrum—showstopping blooms in red, orange, pink, or white grow about one to two feet tall.
Filler option: Queen Anne’s Lace
Zone 5 and 6
These zones have a medium length growth season from March to November, with lowest temperatures averaging -15ºF to -5ºF.
Consider these flowers:

Front: Floss flower—these blue/purple flowers grow from six inches to two feet.
