Zinnia are one of the old-fashioned flowers that make excellent cut flowers and have always had a place in my gardens. While I tend to grow many of the older open-pollinated varieties, the new hybrids have some very special qualities.
This plant won an award for being a good bloomer in all parts of North America in many different gardens and trials so it’s a good safe bet in case you want something in this class of plants.
There are two plants on my trials this year” ‘Profusion Double Hot Cherry’ and ‘Profusion Double Deep Salmon’
Zinnia ‘Profusion Double Hot Cherry’
About This Plant
- Sunshine: Full sun to light shade
- Height: 14-inches tall
- Plant Apart: 24-inches (wider than tall)
- NOTE: if you are in the North (USDA 5 or colder) you may want to bring this planting-apart distance down to 18-inches as the plant may not get to full width (depends on summer heat)
- Bloom time – mid-summer until frost
- Use: general garden growing, cut flowers and containers (shorter varieties do well in containers)
Zinnia ‘Profusion Double Deep Salmon’
How To Start Seeds
Sow onto soilless mix and use bottom heat to maintain a soil temperature of at least 70F if you want good germination. Cool temperatures will slow down the germination or kill the seed.
Sow seed directly on the soil and either allow to sit uncovered or barely cover the seed. This seed does not need darkness to germinate. I’ve found they grow best if lightly covered as the seed root will head immediately down and not twist around looking for “down”.
Water with luke warm water for best germination (this is true of all annual germination)
You should see germination within 3 weeks and potting up into their growing container 2 weeks after that. Put each plant into a 3-4 inch pot if you want it to grow really well.
Transplant outdoors after all danger of frost.
April 4, 2013 Seed unpacked and a few sown in the seed starting racks. Remainder to be direct sown in the garden for trial.
July 28/2013: Decent plant – good blooms. Excellent choice for the mid-size zinnia. Held flowers well (no flopping) and flowered heavily.
