Seeds for Rock Garden Plants
TRM487 Palmers Penstemon ( Penstemon palmeri )
One of the few scented penstemons, this is a great rock garden plant as it thrives in almost any soil and dry condition. Spectacular 3 to 5 foot tall spikes bear huge,
tubular, light pink, fragrant flowers from March through September.
It has proven to be a valuable re-vegetative species on burned sites. It is drought tolerant. It is a short-lived (4-5 years), evergreen, native, perennial herb.
Palmer's penstemon is found in the western United States from Wyoming south to New Mexico and westward to California. Although Palmer's penstemon is short-lived, once established, it is self-perpetuating because of its abundant seed production and seed dormancy which allows it to establish readily when conditions are favorable for germination and survival. Hardy to zone 4.
3497 Purple Robe ( Saxifraga Arendsii )
An excellent groundcover that is compact, free-flowering, and easily raised from seed. These charming perennials quickly form an evergreen verdant mat. The surface-spreading mossy leaves are evergreen for year-round effect.
When your spring bloomers are starting to fade, the dense mats become covered with small carmine red, cup-shaped flowers held upright on ankle-high, strong stems.
Also, known as Mossy Saxifrage or Purple Robe ground cover, Saxifrages grow well in containers, beds, rock gardens, and anywhere a low-growing, spreading ground cover plant is desired. Mossy Saxifrage plants prefer well-drained soil and full sun to partial shade conditions. Purple Robe does not do well in the hot humid areas. It is both deer and rabbit resistant.
Grows about 6 inches tall, a perennial hardy for zones 4-9.

This is a popular rock garden perennial for the spring garden. It establishes itself easily from flower seeds sown directly outdoors. It forms a low, trailing mound of silvery-gray leaves, and it produces a mass of bright-yellow flowers in mid to late spring.
