The beautiful flowers come in saturated shades of chartreuse, orange, pink, purple, red, white, and yellow with single, semi-double, and fully double flowers plus dahlia, globe, and cactus flower forms.

Highly appealing to pollinators such as bees, the nectar-rich plants are also loved by butterflies and hummingbirds but avoided by herbivores such as deer and rabbits.

Heat lovers, they produce a continuous display of flowers even in the hot days of high summer. 

And they range in size from small dwarf varieties to tall ones of 36 to 40 inches – although the shorter types are the better option for pots and planters.

Are you ready for some zesty potted zinnias this summer? Then let’s jump in for all the details on zinnia container care!

Containers provide a fun and exciting way to garden in small spaces, create interesting tableaus, or to soften hardscape areas like decks, patios, concrete slabs, or gravel walkways.

These easy-care annuals thrive in pots and planters of any shape, size, or material, and their fantastic, long-lasting colors beautify any kind of container!

Wait until all danger of frost has passed to set out transplants – overnight temperatures need to stay above 50°F.
