Russian Sage

Russian Sage (Perovskia atriplicifolia) is a low water perennial, native to central Asia. It is primarily planted because it flowers profusely from late spring until frost. It does well in both xeric and higher water landscapes. In fact, after establishment Russian Sage can grow without any supplemental watering although flower production and plant growth may be reduced. The photo below shows a Russian Sage that has not been watered in over 6 years. It receives only what rain Mother Nature provides and continues to flower and expand annually.


Russian Sage is not related to other commonly grown “sages” such as autumn (Cherry) Sage which are in the genus Salvia. Russian Sage grows with upright, whitish gray stems reaching 3’ – 4’ tall.


Russian Sage has an extensive root system and spreads by sending up suckers, growing out in all directions. Annually, it will become a larger shrub.  It has deeply lobed silvery-grey leaves.


The older stems are woody, and younger stems are soft or herbaceous. Like members of the mint family, stems are square in cross section. Russian Sage has a strong scent especially if stems or leaves are rubbed or bruised. Russian Sage produces abundant spires of small, tubular flowers of blue or lavender color. These spires sometimes reach 1’ -2’ in height. Flowers attract pollinators like honey bees all summer.


Russian Sage grows best in full sun, with low to regular water. It is also very heat and drought tolerant. Russian Sage is Hardy to USDA zone 4. Use Russian Sage in the Landscape as solitary plant clumps


or as a border, for example, between properties.


Maintain Russian Sage by cutting back last season’s growth to about 6" – 8" in late winter or early spring before new growth resumes.

Weed Identification: Goatheads or Stickers

Goatheads ( Tribulus terrestris ) are native to Southern Europe, Asia, Africa and Australia. Goatheads are also called stickers, sticker weed, bullhead, devil’s weed, and puncturevine. Goatheads are easily recognized by their prostrate growth form, leaves with leaflets, yellow flowers, and stickers (Goatheads). If you miss’em visually then they will stab you painfully in the fingers as you work your garden, or stick to your clothing and shoes. Goatheads are the primary reason local bicyclists must get “thorn proof” tires for riding on area trails and streets. Goatheads have prostrate stems that radiate outward from one central point. Leaves are compound with smaller leaflets. Lemon yellow flowers form along the stems and fertilized flowers form fruits.   Fruits consist of several attached structures called nutlets (Goatheads). Each nutlet is a single seed that becomes hard or woody when mature. Each seed has two sharp spines that easily penetrat

Weed Identification: Sand Bur

Sand Bur ( Cenchrus longispinus ) is native to North America. It has other names like sand spur, long-spined sand bur, hedgehog grass, and bur grass . Sand Bur is an annual grass usually growing with a prostrate growth form. It is similar in appearance to other grasses prior to seed formation. Individual plants may be 3’ in diameter, sometimes larger. Sand Bur is a common weed of sandy soils but also grows well elsewhere. Sand Bur will often root at stem nodes that are touching the ground. The root system of Sand Bur is shallow and fibrous making them easily pulled (when immature). Sand Bur produces a flowering spike. As seeds begin to form Sand Bur is easily recognized by its numerous sharp or burred seeds or long spines. As the burred seeds mature they are easily separated from the mother plant and their sharp spines stick to virtually anything. Sand Bur can disseminate its seeds long distances because its sharp spines will hitch a ride on skin, animal hides,

Weed Identification: Silver-Leaf Nightshade

Silver-Leaf Nightshade ( Solanum elaeagnifolium ) is a perennial plant usually growing 8” to 20” tall. It is easily recognized by its silver green wavy leaves and stem color,   often thorny stems, and violet colored, star shaped flowers with protruding yellow stamens. Other common names for Silver-Leaf Nightshade are Prairie Berry, Silver-Leaf Nettle, and Satan’s Bush. Silver-Leaf Nightshade flowers from late spring into fall and is native to the Southwestern United States and into Mexico. It is considered a noxious weed in many states. Silver-Leaf Nightshade is poisonous and toxic to livestock. Silver-Leaf Nightshade propagates from both rhizomes and seed found in berries. Green striped berries turn yellow or orange at maturity and then dry to brown.   Silver-Leaf Nightshade has an extensive root system     and can form colonies, which makes it difficult to eradicate.   If you have time and patience, Silver-Leaf Nightshade can be e
