Today, I noticed some tulips coming up in my garden and realized spring is just around the corner. I live in the Denver Colorado area and the general rule around here is that you are safe to plant annuals and new perennials after Mother’s Day, but I usually always take a chance and plant my Colorado flower garden a little earlier.
The following map shows the different hardiness zones in mainland USA. Colorado is in zones 4-6. Specifically, the Denver area is in zone 6a. At the nursey or in a catalog, be sure the plant you want to purchase will survive in the zone you are planting it in.
So, will Tulips grow in a warmer climate than zone 6? Only if they get an amount of cold required – which Is usually 2-3 months. Some years, I will bury some Hyacinths or Tulips in pots in the garden then dig them up and bring them in around late January/early February. The aroma of the Hyacinths in winter is magnificent. You can also purchase forced bulbs from the grocery store but it’s fun to do it yourself as well.
Here are my favorite flowers to plant in Zone 6 with some growing facts about each:
I will add more interesting plants to this list as the season goes on. If you have any questions or comments about my Colorado flower garden, please don’t hesitate to contact me. I love to chat about gardening!
Also, I would love to hear about your favorite plants in your garden wherever you are, whatever the climate.
