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).

Plant Information

Peacock Orchid Bulbs, also known as Gladiolus Acidanthera, are an absolute knock-out in the garden. They are extremely easy to grow and their display and blooms are some of the most exotic anywhere.

The name says it all. Like a peacock, these exquisite flowers will rise above the foliage and open like spectacular rare orchids. If you cut them, your arrangement will be absolutely spectacular. Many a gardener has tried this one and become totally addicted to growing it. Your neighbors have never seen it, and they'll never know that all you had to do was stick a few bulbs into the dirt, to have this incredible beauty in your garden. Enjoy!

From a gardener who's grown it: 'I planted ten corms in semi-frozen ground in early March of 2002. The soil and sun conditions varied from poor sandy soil with almost full sun to semi-rich soil in almost full shade. Regularly treated the soil with fertilizer every 2 weeks. None of the corms had sprouted by late spring, so I continued planting around them, figuring that the planting was mis-timed and the corms had died. In early summer, over a 3-week period, all of the corms sprouted. In mid-August, when the plants had reached anywhere from 18'-24', they began to flower. BEAUTIFUL, and with a nice (almost cologne-like) aroma. Blooms kept appearing until late October. Although this plant cannot survive the winters here in Zone 6b, they are SO easy to grow that I plant them every year (basically treating them as an annual). It seems that EVERY corm that I plant sprouts, so there's no guesswork involved.'.....from a subscriber to DavesGarden.com, gardening in Stratford, CT

Us vs. The Big Box Store: Gladiolus Bulbs

Each season, we head over to the big box store in our area and choose several Bulbs, Plants and Seeds to compare against our selection. This spring, we purchased 50 Gladiolus Bulbs to compare and the difference is quite revealing.

I’d like to start out by mentioning the difference in shopping experiences. I walked into the big box store and headed straight to the back, where I knew the garden section was. I walked through aisles of grills, patio sets and annual hanging baskets until I found someone to speak with. They quickly answered the phone and I waited several more minutes until I could ask, "Do you know where the Gladiolus Bulbs are?" They weren’t sure what I meant and finally an entire wall of Summer-Blooming Bulbs caught my eye. I chose their "Gladiolus Mix" bag of 50, which most resembled our Gladiolus Rainbow Mix, which we also carry in a bag of 50 bulbs.

When you shop on our site, we have a wealth of information on growing and caring for Gladiolus at your fingertips, as well as an extremely helpful and knowledgeable garden staff, several of which are certified Master Gardeners. We not only want you to have success in growing our products, but also want you to feel confident in everything you plant – Which is why we focus so intently on how-to information as well as have a 100% satisfaction guarantee. We urge our customers to write reviews on our products, positive or negative, so you know what grows well in different areas and what doesn't. We also offer live chat and service over the phone 6 days a week, offering growing advice as well as helping to place orders.

This photo also helps to show the true difference between us and the Big Box Stores. Brian, one of our employees and garden-enthusiasts helps to explain why a bigger flower bulb is better.

"Several flower bulbs are part of the onion family, and because of this I like to use Onions as a representation of how important bulb size is. Which of the onions on your shelf go bad first? The smallest ones! Larger onions are more resilient, taking longer to dry out/rot and can withstand swings in temperature better. Flower bulbs are the same. Larger bulbs will withstand disease, draught, large amounts of moisture, and colder temperatures significantly better than the smaller ones. They also produce taller growth and larger blooms."

With American Meadows, you’re not only getting access to our thirty years of gardening experience, but are also receiving the largest, highest-quality bulbs available, inevitably producing larger, healthier blooms in your garden. Happy Gardening!
