Planting Tips for Zinnia grandiflora
These plants won’t begin to grow until warm summer weather has arrived. The long thin string-like roots are brittle and do not like to be disturbed when transplanting, so don’t scratch out the root ball. When transplanting while it is still cold, water the plant thoroughly only once. Continued watering during cold weather will rot the roots. Don’t start to water regularly until the weather warms and the plants begin to grow.

Comments about High Country Gardens Zinnia grandiflora Gold on Blue:
This plant met and went beyond my expectations. It was planted in a low water garden (watered once a month, weekly in 90+ degree weather in our hot dry summers), in lean clay with 2" gravel mulch. So bright and eager to flower. I planted just one to see how it would do in that area and will definitely add more.

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
