Best Zinnia Seeds for Cut Flowers at Home
Zinnias may be the closest thing gardening has to instant gratification.
They grow quickly, tolerate summer heat, bloom in almost every color imaginable, and produce more flowers the more you cut them. For anyone starting a home cutting garden, zinnias are hard to beat.
At DollarHeirloom, we carry a lot of zinnias because no single variety does everything. Some produce large statement flowers, some bloom endlessly, and others add smaller flowers and interesting textures to a bouquet.
What Makes a Good Cutting Zinnia?
For bouquets, look for tall plants with strong stems. Varieties reaching 24 to 48 inches generally make better cut flowers than compact border zinnias.
Large double blooms give arrangements a fuller, more formal look. Smaller and single flowers create a looser garden style and are often especially attractive to pollinators.
The good news is that zinnias are inexpensive enough to try several types. Browse our complete Zinnia Seed Collection and plant a mix rather than betting the entire bed on one variety.
Our Favorite Zinnias for Bouquets
Dahlia-Flowered Zinnias
For large, bold bouquets, start with our Dahlia Flowered Mixture.
The blooms are full, colorful, and substantial enough to become the centerpiece of an arrangement. These are the zinnias to grow when you want flowers that look impressive without requiring impressive gardening skills.
State Fair Mix
State Fair Mix produces tall plants and large flowers in a broad range of colors.
It is a dependable choice for gardeners who want traditional zinnia bouquets with plenty of variety from a single packet.
Cut and Come Again Mix
The name says most of it.
Our Pumila Cut and Come Again Mix produces branching plants with a steady supply of colorful flowers. Keep cutting them, and they keep producing.
This is one of the varieties we would choose for a smaller garden where every plant needs to earn its space.
Smaller varieties such as Lilliput Mix and Persian Carpet Mix are useful for adding smaller blooms, contrasting colors, and texture around the larger flowers.
How to Grow Zinnias for Cutting
Wait until frost has passed and the soil has warmed. Zinnias want full sun, decent drainage, and enough room for air to move between plants.
Sow seeds about 1/4 inch deep and keep the soil moist until they sprout. For a longer season, plant another short row two or three weeks later.
When young plants reach roughly 8 to 12 inches tall, pinch off the growing tip just above a set of leaves. It feels wrong the first time you do it, but that one cut encourages the plant to branch and produce far more flowering stems.
When to Cut Zinnias
Zinnias should be fully open before cutting because they do not continue opening much in the vase.
Use the wiggle test: gently shake the stem just below the flower. If the bloom flops around, leave it a little longer. If the stem stays firm, it is ready.
Cut long stems early in the morning or during the cool of evening. Remove any leaves that would sit underwater and place the stems into clean water immediately.
Keep Cutting
The secret to growing more zinnias is using them.
Cut flowers regularly and deadhead anything you leave behind. Once plants begin producing mature seeds, flowering slows down.
That may be our favorite thing about zinnias: picking a bouquet is not taking something away from the garden. It is encouraging the garden to make another one.
Start with two or three varieties, keep a few jars near the sink, and cut flowers without waiting for a special occasion.
