USDA Hardiness Zone Map

Digging Dog Nursery is 3 miles from the ocean, on a ridge top, bordering both Zones 15 and 17 (according to Sunset's Western Garden Book) or Zones 8 and 9 (according to the USDA Plant Hardiness Zone Map).

We have a relatively mild climate, with the coldest temperatures generally in the low 20's and the warmer days reaching close to 80°. Occasionally we do have cold winters when temperatures dip into the low teens.

USDA hardiness zones are indicated for each plant to suggest minimum tolerable cold. Use these only as a loose guideline, keeping in mind the varied factors which can cause a plant to be vulnerable to cold. Remember, micro climates can be created in your garden, making it easier to raise supposedly tender plants in colder zones. In some areas, a cold pocket may force the temperature lower thereby creating problems for a hardy plant.

Height & Width Estimates

The first number given represents ultimate height of the plant, including flower height above foliage. The second number is the width. Use these sizes as a reference for your garden planning and designing.

The figures are approximate and may vary according to soil fertility, exposure to sun, and other environmental conditions. The sizes we list have been observed here in our home garden, and in other Northern California sites, both coastal and inland.

Most grasses and perennials will achieve estimated proportions in 2 growing seasons, shrubs in 3-5 years. In the tree section, the growth rate, size attained in 10 years, and/or the tree's ultimate height has been listed.

Bloom Times

The months stated represent the approximate flowering times for each plant. These may vary depending on your specific environmental conditions.

Plant Containers

We ship well-established plants which are grown in the following container sizes:

Small Band:
2-½" square x 5" deep
Medium Band:
3" square x 5-½" deep (the majority of our perennials & grasses)
Squat Band:
3-¾" square x 4-½" deep
Large Band:
4" square x 6" deep (most of our trees & many of our shrubs)
Quart:
5" square x 6" deep.

Occasionally, plants will be available in liners (2-¼ square x 3-¼ deep) or landscape plugs, and will be discounted $1.00-$1.50 off the regular price.

Digging Dog plants are removed from their containers, and their firm, intact rootballs are placed inside plastic bags prior to shipping.

When Your Order Arrives

If you're not ready to plant when the order arrives, open the box immediately and remove the plants. Place them in a shady spot, making sure they don't dry out. Newly planted selections should be protected from hot sun and drying winds, and watered adequately.

PLEASE READ THIS NOTICE PRIOR TO PLACING YOUR ORDER!

Due to the unprecedented influx of orders, phone calls and emails that we have been receiving, our small family run business of not quite a dozen people, is sadly behind at this time. The combination of extremely cold weather in January and February, as well as vendor plant shortages and unanticipated delays, are adding to our difficulty of assigning ship dates in a timely fashion. Please know our team is working diligently to catch up. Orders are currently taking up to 5 weeks to review. To be as fair as possible to our valued customers, we are processing orders in the order they were received. We appreciate your patience and hope that you can accept our heartfelt apology for any inconvenience.
