Sedum reflexum 'Blue Spruce'

Highlights

'Blue Spruce' (Sedum reflexum, also known as Petrosedum rupestre) (Linné): A standout among hardy, low-maintenance, ground cover succulents. Its stiff, needle-like leaves hold a soft blue-green and flush salmon pink in winter. They are super hardy and will happily pass the winter under snow and tolerate temperatures down to -30F (zone 4).

Once established, 'Blue Spruce' can tolerate months of drought but regular water in the spring to summer growing season will encourage vigorous growth. It makes a wonderful ground cover because it is a fast, robust grower without aggressively overrunning companion plants. The growing season also brings a sea of bright yellow, star-shaped flowers that attract pollinators.

Over the centuries, gardeners have found many great uses for S. reflexum, including rock gardens, borders, retaining walls, vertical plantings, and green roofs. 'Blue Spruce' can also grow in outdoor containers with great drainage and full to partial sun, eventually trailing over the edge of the planter.

How fast and how big will the blue spruce spread? See answer

See more »

Follow

3 years ago  •  Staff Answer

'Blue Spruce' can spread around 2 feet wide.

As far as how fast it can spread is concerned, that depends on many different factors like sunlight availability, water availability, soil quality, and fertilizer. It's difficult to say but, as a general rule, it can spread 1"-2" per month in the growing season. What I can say is that it spreads very quickly, if cared for properly, and, if you're not careful, can coke out slower growing plants. See full answer »

That is in inches. For quick reference, if a number has full quotes next to it, like 5" lets say, then the units are in inches. If the number has an apostrophe next to it instead, like 5', then the units are in feet. See full answer »

Sedum, in general, taste bad to deer. However, there's a reason plants get called deer resistant vs. deer proof.

If Sedum gets established, deer don't mess with it, but when it's first planted they may pull it up, even if they don't eat it. See full answer »

Certainly! Hardy Sedum and Sempervivum thrive in zone 9a (and lower zones) and are resistant to rabbits. Cacti also resist rabbits due to their spines. Click the link below to check those cacti out.

You're going to want the succulent types in this Frost Hardy Ground Cover category. All these types of Sedum, Delosperma, Rosularia, and more are super easy spreaders that thrive with cold winters and hot, dry summers. Use the "Grow Zone (Hardiness)" filter on the left of that category page to see only types that are hardy in your climate. To check what grow zone you're in, enter your zip code into this USDA Hardiness Tool.

What kind of soil should I use with succulents? See answer

Shop Succulent Soil Here

Succulents need grittier soil than other plants because they are adapted to dry conditions and store water in their leaves. Regular potting soil mixes stay damp for long periods of time, which can cause rot in succulents. Instead, use a sandy, well-draining soil so you can water thoroughly without leaving your succulent in standing water.

When should I plant my succulents after they arrive? See answer

See more »

Follow

4 years ago  •  Staff Answer

Our plants can be transplanted immediately upon arrival.
If you want to wait to transplant, they can remain in their original containers for up to a month. If the pots came in a plastic carrier tray, remove the pots from the carrier tray prior to the first watering.

Keep the plants indoors near a sunny window or outdoors under a roof (only if outdoor temperatures stay above your succulent's minimum hardiness temperature). Water only after the soil is fully dry by drenching from above with a faucet, hose, or watering can. Gently shake excess water from the leaves and allow containers to drain completely.

Do I need to fertilize succulents? See answer

See more »

Follow

4 years ago  •  Staff Answer

Fertilizing is not necessary, but it is a good option for succulent growers who want to encourage faster, larger growth. It can be used on mature plants with established roots. Only fertilize in the growing season (spring and summer for most varieties) to avoid weakening or burning dormant plants. Use a light touch and make 2-3 applications of low-Nitrogen, diluted fertilizer each year (N-P-K ratio around 5-10-10). You can find specially-formulated cactus / succulent fertilizers in most garden centers or go organic with compost tea or bone meal.

Example: Miracle-Gro Quick Start, diluted to half strength
