Zone Finder

Don't know your zone?

Zone 11:

Ships Week of March 21st

This zone is the warmest, and refers to any region that seldom dips below 40°F. Zone 11 is considered to be frost-free.

Zone 10:

Ships Week of March 21st

Plants that love heat and humidity do very well in this tropical climate. Zone 10 receives plenty of rain, sunshine, and warm temperatures. Its average annual low temperature is 30–35°F.

Zone 9:

Ships Week of March 21st

This zone includes the thermal belt of California's Central Valley. In this growing region, gardeners don't worry about cold hardiness like they do in other parts of the United States. The bigger concern here is the summer heat. Weather in the thermal belt is affected by both coastal and interior weather patterns. Hot and very dry air is pushed in from the inland while the ocean provides cool and moist air. Plants that prefer cool and moist summers are difficult to grow in this region, whereas heat-loving plants thrive with minimal attention. Zone 9 has very hot summers, while winters have low temperatures ranging from 28–18°F, although frost is rare. Rain between November and April averages 2 inches per month. There's constant sunshine during growing season. Plants that do well in this area with full sun are butterfly bushes, lavender, black-eyed Susans, hibiscus, and sedum. Part-sun plants include honeysuckle, phlox, passion flower, hollyhock, and bee balm. Bleeding hearts would work great in shade.

Zone 8:

Ships Week of March 28th

This zone ranges 10–20°F as the average annual low temperature. Most parts of Zone 8 enjoy a temperate climate with mild winters. Summers are generally warm with cooler night temperatures. Due to the long growing season, this zone is home to many beautiful gardens. Although it's too warm for lilacs, many other plants from Zones 7 & 9 may actually do well here depending on the microclimate of your location. Suggested for some plants that should flourish in Zone 8 are angel trumpets, astilbe, bee balm, bleeding hearts, columbine, daylily, hostas, and butterfly bushes.

Zone 7:

Ship Weeks Vary by Location:

  • 7a ships week of 4/11
  • 7b ships week of 4/4

This zone has hot summers and mild, but pronounced, winters that sharply define the season without severe winter cold or enervating humidity. This zone also has a climate conducive to growing such plants as peonies, lilacs, and flower bulbs. In Zone 7, typical winter lows range from 35–26°F (2 to -3°C with record lows averaging from 18–0°(-8 to -18°C).

Zone 6:

Ship Weeks Vary by Location:

  • 6a ships week of 4/25
  • 6b ships week of 4/18

Warmer summers and cooler winters distinguish Zone 6 from coastal Zone 5. With a long growing season from 155 days at Cottage Grove to 280 days and 40–55 inches of annual precipitation in most places. If you live in Portland for example, it's among the mildest parts of Zone 6. Zone 6 averages 10–15°F (5–8°C) higher than those along the coast, while winters are the warm summers of this zone. The cold winters make this area exceptional for growing plants like peonies and plants that need at least 6–8 weeks of cold weather to grow and bloom properly.

Zone 5:

Ship Weeks Vary by Location:

  • 5a ships week of 5/16
  • 5bn ships week of 5/9
  • 5bs ships week of 5/2

Summer highs run between 65°–70°F (18–21°C) along the coast, and 70–75°F (21–24°C). Such mild temperatures are great for growing begonias. Steady breezes and lower temperatures, especially along the coast, make windbreaks and warm microclimates critical for heat-loving plants. Average January minimum temperatures range from 33–41°F (1–5°C), with annual lows averaging a few degrees colder.

Zone 4:

Ships Week of May 23rd

This zone has more cold than neighboring Zone 5, more snow, and a shorter growing season. Compared to neighboring zones in Alaska and Canada, however, it has less winter cold and a longer growing season. No zone grows better perennials and bulbs. Average winter lows in Zone 4 range from 34°–28°F with extreme lows averaging 8°–0°F. The growing season is 150–200 days long, but because Zone 4 summers are temperate (high average from the low 60s to the 70s), plants take more time to develop.

Roberta's 6-pc. Snow White Tuberose Collection with Fertilizer 2.7 5 67 67
Very beautiful and fragrant This will be year three for my Tuberose. They bloom in late fall long after the rest of the garden has long faded away. They have beautiful blooms and smell wonderful. Mine are in planters and once done blooming I cut them back and put them in the basement. They have done great and am looking foward to those blooms again this year. Wish I could post a picture here. I live in Michigan. 05-26-15
Didn't grow I bought a prior tuberose collection from Roberta's many years ago. They never grew, even though by then I had decided to plant all Roberta's plants in pots where I could control soil/water etc. since I had such bad luck with their plants growing when planted in the ground. And I live in San Diego where practically everything grows. I'm reviewing the tuberoses, because they were probably the most spectacular fail of all of my purchases from Roberta's. Is it possible this particular Snow White offering is different? I hope so, but be aware. 05-12-15
Still waiting Planted these as soon as they arrive. 3 weeks now. Still waiting for some growth. 05-05-15
poor performer Well the one tuberose bulb that bloomed looked great! However the rest just never happened. Some got stalks but never flowered and some never came up at all. I called Roberta's and was surprised when the lady said they don't usually bloom the first year as I specifically remember the salesman saying they bloom the first year! Well they haven't bloomed the 2nd year either. They sent me three more this year and some snapdragons to make up for it. These new tuberose still haven't sprouted - and I planted them at the same time as some gladiola's that are coming up now. 04-23-15
Snow White Tuberous I ordered these, planted as directed. They never came up in late summer or fall nor yhe following year. I see them advertised again this evening. I was disappointed, and customer return is too late. 04-21-15
Huge Success - in spite of neglect Thank you, thank you, Roberta's Gardens! Last year's purchase of the Snow White Tuberose suffered greatly as they arrived when we were out of town, stayed in the box for WAY too long, then were crowded into smaller than recommended pots and watered when remembered. Despite the neglect, one of them blossomed and the sweet fragrance was intoxicating! This year, they're getting the treatment and care they deserve - have nearly committed the growing guide to memory! These beauties survived my awful treatment so I can only credit Roberta's Gardens for such hearty plants! 04-21-15
These will last longer than me! I purchased these from Roberta's several years ago while I was living in Kansas. I had planted them in pots and I would put them out in the summer and place the pots in the basement during the winter. I have to admit it took about 2-3 years for them to mature enough to bloom. After a few years, I moved to Georgia and planted them in my garden. Not only did they survive the winter, but they expanded enough that I could split them up for planting in other areas of my garden. And, the number of blooms multiplied substantially. The fragrance is wonderful as well. The blooms actually kept coming until about October-November of last year. They are a great 18"-24" addition to my garden. 04-11-15
White Tuberose Last year all mine came up and flowered,this yeari see they are just peeking out of the ground. 04-09-15
They don't survive Sadly, I have bought this item twice, as I know how awesome they can be, but each time they have grown a lot but never bloomed then didn't come back in the spring. Too much money for nothing 04-09-15
Bad Plants I have attempted to grow these a couple different times with NO success. I don't know how Robertas stays in business or why QVC carries their products. So many bad reviews! 04-09-15
Died Bought this a couple of years ago when I lived in California, planted just like it said and the thing never did a thing but die. Would give no stars if I could. 04-07-15
Trying Once More Well, last year when I got these, I kept them very moist and fertilized every time I watered them. I got a few flower stalks. I brought them in for the winter and put them in my garage near a sunny window...they all got black and mushy. It was cold here in the Atlanta area but not that bad, so I don't think they are as hardy as advertised. But, they're guaranteed, so I'm going to give it another try. If they don't do well this year, that's it for me...no more tuberose. 04-01-15
