Moisture Tolerance: Adapted to relatively dry conditions and requires some supplemental irrigation only in locations where summer moisture is infrequent. Soil: Adapted to a range of soil types and conditions, including alkaline soils, but requires well-drained conditions. This species commonly grows at elevations ranging from 3,000 to 8,500 feet. Often found within a wide range of plant communities, including woodlands, mesas, grassy plains, dry prairies, and slopes typically on gravelly or rocky soil. Native Habitat: Castilleja integra is native to the high plains and foothills of Arizona, New Mexico, Colorado, and Texas. To satisfy the hemiparasitic nature of wholeleaf paintbrush, as well as maintain the aesthetic value of the garden, a plant species with good host traits and with complimentary size and color should be chosen as a propagation companion. Wholeleaf paintbrush can be used in xeric beds or borders. Plants are herbaceous, dying back to below the ground each fall and sprouting underground crowns each spring.
Mature plants are about 12 to 15 inches tall and produce up to a dozen flowering stems. The intense color exhibited by wholeleaf paintbrush is dominating and the plants are best used to intentionally draw the eye to a specific part of the garden. Flowers of wholeleaf paintbrush are brilliant orange-red and bloom over a significant period of late spring and summer, typically from May into July. Wholeleaf paintbrush adapts more easily to cultivation than most other species from this genus, meaning that with the use of proper techniques, it can be cultivated and marketed as a horticultural product. Appropriate host plants are essential for maintaining health and ultimately for survival of paintbrush growing in either pots or the garden. The key reason for minimal use in gardens is production barriers caused by the hemiparasitic (partially parasitic) nature of this genus. Uncommon in cultivated gardens, species in the Indian paintbrush genus are worthy of greater attention from the landscape industry. Some of these flowers, especially those in the Alpine zone, are endemic to Great Basin National Park-meaning they are only found here in the Great Basin, and nowhere else on Earth! It is important to try to keep non-native and invasive species out of the park to keep the habitats here safe for our native and endemic species.Scientfic Name: Castilleja integra Common Name: Wholeleaf Paintbrush, Wholeleaf Indian Paintbrushĭescription: Wholeleaf paintbrush is one of the universally recognized and adored wildflowers of the southwestern U.S. You may also find that there are wildflowers that occur at different elevations in the park as well. Mixed Conifer Forest (7,000-10,000 ft.)Īs you make your way through the park-either on your hike, or on your way up the Wheeler Peak Scenic Drive-watch for the changes in plant life that defines the different zones.Intermountain Cold Desert Scrub (below 5,000 ft.).Great Basin National Park has seven major zones of habitats, depending on the elevation: Zones often occur in specific elevations, although you can often find more than one zone at the same elevation throughout the park. Zones are usually determined by the primary species of trees or shrubs found in the area. Different species of plants are better suited to different environmental factors, which is why you may also notice changes in the kinds of plants you see in different sections of the park, especially at different elevations. As you travel to higher elevations in Great Basin National Park, you might notice differences in the temperature, precipitation, oxygen levels, and other environmental factors. difference leads to a wide variety of plant communities through a phenomenon called, “altitudinal zonation”. above sea level between its highest and lowest trails. Great Basin National Park ranges in elevation from 6,825 ft. Indian Paintbrush grows along side a trail.
