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).

1998 Green Thumb Award Winner + 2008 Plant Select Winner. 36-48" tall x 18" wide (seed propagated). Cookes Peak's pine-covered summit rises to over 8,400 feet, towering over the desert near Deming, NM. Looking south you see the panorama of Mexico and its vast expanse of the Chihuahuan desert. From Scrophularia's high altitude habitat of over 7,200 ft. on this mountain's slopes, Panayoti Kelaidis of the Denver Botanic Gardens collected the seed our stock plants were grown from. Scrophularia, a very rare Penstemon relative, is a garden treasure blooming from early summer through fall with long wands of white-lipped, cherry-red flowers. The dark green angular foliage is also quite handsome. The plant has a tall, informal habit and will lean over and intertwine with tall neighboring plants for support. Plant it next to Pitcher's Sage or 'Blue Fortune' Hyssop for this very reason. Very popular with the hummingbirds, too!

Planting Guides

Scrophularia macrantha (Red Birds in a Tree) is a long-blooming native wildflower that is easy-to-grow and provides ample nectar for hummingbirds. It's resistant to browsing rabbits.

Preferred growing conditions:

  1. Scophularia grows will in a wide range of soil types, but not clay.
  2. It should be mulched in dry climates with crushed gravel, pine needles and other non-water retentive mulch materials like crushed pecan shells. Avoid bark mulch and wood chips, as these can cause fungal disease in rainy conditions.
  3. Requires deep, regular watering in dry climates.
  4. Plant in full or part sun conditions. Afternoon shade is best in hotter climates. Full sun with regular irrigation is fine in moderately hot summer regions.
  5. Adding just a few handfuls of compost and Yum Yum Mix in the planting hole is enough. Avoid rich, highly -mended soil as this encourages rapid, soft growth and the plant will likely not make it through the winter.

Special comments:

  • Scrophularia is not a long lived perennial and gardeners should expect to replace old plants every 3 to 4 years. It is a star of the garden and well worth the investment.
  • Avoid chemical fertilizers and too much water, as this will cause the plant to grow quite large and floppy, reducing winter hardiness and shortening its lifespan in the garden.

Garden care:

  1. Fertilize Scrophularia just once in fall with Yum Yum Mix and Planters II
  2. To improve cold hardiness, leave plants standing through the winter and cut back the stems to a height of 2-3" inches in mid-spring.
