My Hardiness Zone ?
The USDA hardiness zones offer a guide to varieties that will grow well in certain climates. Each zone corresponds to the minimum winter temperatures experienced in a given area. Make sure that your hardiness zone lies within the zone compatability range of this variety before ordering.

Size & Spacing

Mature Size

When your plant matures, it will be approximately 15 - 20' tall x 3 - 8' wide.

Recommended Spacing

We recommend spacing these plants 3 - 5' apart to ensure room for growth.


This variety is self pollinating.

In many cases, you may still want to plant pollinating partners to increase the size of your crops, but with self-pollinating varieties doing so is optional. You'll get fruit with only one plant!

I wanted a red grape and I think this will be suitable for the environment that it will grow in. Even though this is an arid location, grapes do well here in Bard, CA

Looks delicious

I chose the Saint Theresa Grape because they look beautiful they are suppose to be sweet and firm.
Angel S on May 3, 2020
These are compatible with my zone 9b. Large farms of table grapes grow in my area and available at local markets, but I like to try something different.

We r a small family winery in the Sangre de Cristo mountains, New Mexico. Our winery is at 7600 ft. These grapes are designed for the high altitude and alkaline soil. We r testing them in our vineyard.

The research on Saint Theresa shows this to be a prolific table grape. My experience with the Univ of Arkansas blackberries and grapes are typically phenomenal improvements to fruit.

My husband likes purple grapes and has started his own grape arbor so I thought he would appreciate these
Andy on Jun 2, 2016
The catalog says this variety is tolerant of alkaline soil. Denver soil is alkaline, so I hope this means less soil amendments will be necessary.
Diane U on May 25, 2016
Cold hardy ... i find it very difficult to believe that where i am is in zone 6a. We planted grapes a few years ago that were hardy to zone 5 and they couldn't take it, plus we lost our best peach tree due to winter cold ... and we almost never can plant our garden before June 1 without having to worry about frost. i get plants rated for zone 4 and they do well.

when does the grape vine come out of dormancy?
cindy o on May 17, 2018
BEST ANSWER: Mine began growing again in April (in northern Virginia). None of them get
more than partial sun, but the Saint Theresa is the most vigorous grower
of the five varieties that I planted
The planting guide speaks of "aclimating" the vines grown in a greenhouse. Since this is a bareroot plant, I assume you should plant it immediately?
terry P on Jun 8, 2016
BEST ANSWER: Yes you should plant as soon as possible. if your conditions are too cold you can keep them in a cool place and keep them damp. not wet but damp with some wet newspaper or something similar. However I recommend not storing them before planting for more then a few weeks.
This is my first year with the Saint Teresa Grape. In the Fall do I leave it untouched for the winter and add some mulch around the base of the plants or should I trim the plant down some first? It's about 2.5 ' tall and about to go into dormancy.
Gary D on Oct 12, 2018
BEST ANSWER: You don't say what zone you're in: I'm in zone 4. I'm only a year ahead of you with St. Theresa Grapes and I'm training them to a double wire fence. I will be unwinding the vines and laying them down and will cover them with straw for the winter. (Snow will come soon enough and provide about four feet of cover!!!) In the very early spring, I will reattach them to the wires and trim them back to 8 buds or so on each cane. If you have only a single trunk this year, next spring cut back to 3 buds each branch (assuming 2-3 branches). Don't try to keep too much foliage or vine as it will take away from fruit production. Good luck!
Is this vine evergreen?
Lois H on Mar 15, 2016
BEST ANSWER: This grape goes dormant just like most other grapes. The leaves do seem a little more green but not abnormally so throughout the winter months. I mulch the base's well in the winter with straw and pick up the leftover straw and put on the garden in the spring. Very good compost.
Do you ship to the UK?
Bernedette G on Sep 15, 2020
BEST ANSWER: Stark Bro's ships across the United States only at this time.
looking for a grape variety that does well in sandy soil zone 4-5?
laRue D on May 16, 2020
BEST ANSWER: We appreciate you reaching out to us. Most things do not do well in sandy soil, we recommend amending the soil. The best sandy soil amendments are ones that increase the ability of the sandy soil to retain water and increase the nutrients in the soil as well. Amending sandy soil with well rotted manure or compost (including grass clippings, humus and leaf mold) will help to improve the soil the fastest.
If you have any further questions please don't hesitate to reach back out to us. Have a great day!
Is the mature height accurate for these Theresa grapes?? 15-20' tall?
OrangeBlossom on Mar 14, 2016
BEST ANSWER: Yes, but if you think about it, the vine will not be growing straight up that tall. On a fence, trellis or arbor, you're redirecting that "height" to the side ??? or better yet, pruning it to maintain your grape vine in your growing space, keeping it manageable and encouraging fruit production.
Can I start the plant indoors?

Fantastic in Northern Colorado at 5900 ft elevation.
Fabulous Flavour! Fantastic for Jelly! Super Hardy! Great growth characteristics! I have 5 plants which I put out in fall of 2008. All are doing extremely well. At the same time I planted 6 other varieties. Three of them have not survived. The other 3 are not as well behaved in growth characteristics... having many suckers at base which need pruning all season. The St Theresa does not sucker at the base after initial training. The Fruit cropping is VERY HEAVY.... it gives a great harvest! The seedless nature makes it a wonderful table grape. It raisons well in my solar food dryer. I have not complaints.... nor aspirations for anything better.

Growing well, but definitely NOT seedless
I have two of these (west side of Denver, zone 4B). Zone 5 grapes have died here in previous hard winters. These are growing well, but last winter was pretty easy. They both produced grapes this year, and every grape has a big, solid seed.

.Better than others . . .
I have 6 varieties of grapes that I planted in 2015. The St t's are growing better than most of the others. No fruit as expected yet. The somerset's have born fruit in each of their 2 yrs. The st t's plants are looking strong and healthy. My climate is a 4.5 and very arid. I have irrigation rights that is required to grow anything up here in N Wy.

Saint Theresa Grape
It is a little premature for me to be writing a review of this grape but since I was asked, I'll tell you what I know.
My plant is too young to be bearing yet. What I was looking for is a vine that will tolerate some shade. Saint Theresa seems to do that quite well. It has grown and spread across the trellis quite well. I expect there will be some grapes next summer.
My main problem this year has been keeping the Japanese Beetles from destroying it. They REALLY like it.
I tried Muscadines in this location a couple of times and failed completely, so the Saint Theresa has been a pleasant surprise, so far.

So far so good
I had very good growth the first year. They came back in spring just fine after a normal winter in zone 4. Growth rate was good and not too aggressive. No grapes yet. But I can see this is going to be a good grape for northern gardens. I am going to buy more.

Good Grape
Got my vines and planted them. They made it trough winter and a very hot summer right now. The vines look good and have grown enough to be trellised. I hope to have my first crop in the spring. They were slow to start and require a lot of water initially, but have thrived with our summer afternoon rains here in Florida. So far so good. Hard to get a bunch grape to grow here.

Pleasantly surprised
I wasn't expecting much after a dismal first couple of months after planting. Come this second season, absolutely fantastic. The vine has tripled in length, and clusters are popping up everywhere. I'm very satisfiedwith with this purchase.

not seedless, though vigorous
I'm bitterly disappointed, since I love purple grapes, St. Therese of Lisieux, and St. Teresa of Avila. The plant was vigorous, and we got a huge harvest on our first year. However, each and every grape has a big, crunchy seed. Not what we were hoping for in a "mostly seedless" variety.

Ours died
Other varieties worked well for us, but not the St. Theresa. We live in zone 4.

Robust first year growth. Experienced later leaf-out than other varieties, but is now growing well in its second season.
