Unique in that the leaves are thin and willow-like they still harbor plenty of waxy perfume. A somewhat gnarled looking shrub over time with plenty of character. In May-July 6″ long stems erupt from the top of the shrub, elongate and produce clusters of large pure white flowers. Blooms for an extended period but each open flower lasts only one day but is replaced by a steady supply. Full sun and average to enriched soil. Water to establish then less to none in subsequent years. In time it develops a shredding, twisted, gray trunk. Moderate deer resistance. Aromatic on warm days. Mixes very well with Arctostaphylos as well as Ceanothus. A really great rock rose. Tp 3′ x 3′ in 5 years.
Very large growing deep green aromatic Cistus with enormous clear white flowers for an extended period in May-July. The flowers are so large they are reminiscent of the Matilija Poppy (Romneya coulteri) and they virtually obscure the foliage in bloom. To 8′ tall x 8′ wide very quickly. The winding and shredding trunks that develop are cinnamon brown and have a wild, gnarly appearance with age. Excellent cold hardiness especially if you avoid rich, amended soils. Native unimproved soils that drain are best. Handles clay soils well especially if on a slope. Completely drought adapted, no summer water is required. The resinous deep green foliage emits a sweet balsam aroma on hot days.
Excellent performance- including superior cold hardiness and incredibly floriferous is why we grow this moderately large spreading rockrose. Grass green linear foliage in dense and always fresh on an upright and spreading shrub. Grows in tiers which is pretty and displays the copious single white flowers well. Flowers appear daily from May to July. To 3′ x 5′ and low and spreading initially then lifting itself up gradually. Excellent cold hardiness. We’ve tried many, many Cistus planted out at our Wholesale Nursery site in Wilsonville- at least one zone colder than the city of Portland. This carefree shrub has sailed through 5ºF multiple times with NO DAMAGE and thrives in clay soil on a hillside with absolutely no summer water. As with all Cistus avoid overly enriched soil and too much summer water. Neglect is this tough shrubs friend. Moderate deer resistance. This is confused in the trade and may also show up from time to time as ‘White Gem’- its not.
Compact low growing Rockrose with spectacular hot magenta flowers from May to July and sporadically after that. The large flowers (3″) cover the handsome felted light green foliage. To 2′ x 3′ in 6 years- wider with time. Full sun and poor to average well drained soil. Light to little summer water. Hardier to cold and more compact if you avoid rich soil. Tough little evergreen plant. Protected locations like a hot south facing hillside are ideal. Scattered flowers in late summer to early autumn.
A large growing improved rockrose with huge white flowers with a large red basal blotch on each petal. Deep green foliage takes on maroon tints in cold weather. To 4′ tall and 6′ wide forming a dense outline. Blooms May to July in a daily procession of flowers. Each blossom is 3″ across. Excellent cold hardiness to 5ºF or lower- adaptable to the coldest western Oregon gardens. Grows quickly in average, well drained soil Avoid overly enriched sites which will decrease cold hardiness and lead to rank growth. Lean conditions produce the most dense and cold hardy shrub. Great for rough areas in the back ground. Completely drought adapted- no summer water required. Give it room to spread. I’ve had great success with this shrub on a hillside of rocky clay soil that is strictly unwatered in summer. It and all Cistus present the ability to compete with invasive weeds such as introduced grasses. These invasives quickly out compete many things, but not Cistus. Water deep and infrequently or once established not at all. Rock roses can be prone to breaking in ice/snow. Usually, it is just cosmetic and the plant recovers. Our selections we have observed through many snow events (including a 16″ fall in 2008) and have observed no breakage. One of the very best Cistus selections.
After growing a whole bunch of Cistus this variety has risen to the top. Upright growing deep green evergreen shrub to 5′ tall and 5′ wide. The thin deep green leaves have the sweet fragrance of balsam. Beginning in May a constant procession of 3″ white flowers with a red basal blotch on each petal. Each flower lasts a day but there is a constant supply waiting in the wings. Full sun and average well drained soil. Tolerates clay soils well. If you give it a touch of supplemental summer water it will often extend the bloom season all the way until September. Exceptionally cold hardy. One of the finest rock roses.
Compact white rockrose is a fantastic hybrid that gives this shrub several outstanding attributes. A dense compact habit heavily clothed in small deep green leaves. To just 3′ tall and 4′ wide forming a dome. This dense habit resists splitting in ice and snow. From May to July a massive constant procession of pure white flowers. Often bloom is so heavy that it obscures the foliage. Each flower lasts just a day but is replaced by a seemingly never ending supply. In autumn the spent flower calyxes turn bright orange red and are showy- especially when backlit by the sun. Great landscape shrub for hot sites in any well drained soil that does not become boggy. Avoid overly enriched soils for a more cold hardy and dense growing plant. Easy Cold hardy to near 5ºF. Little to no summer water.
A tough, cold hardy, and spectacular rockrose in bloom. Gray foliage is a great backdrop to the huge (3″) pure white flowers with a central zone of yellow stamens. The flowers appear daily but en masse for weeks in April to early June. Moderate growing evergray shrub to 3′ x 5′ in any well drained soil. Extremely drought adapted and requires NO supplemental irrigation when established. Avoid overly enriched soils which will lead to rank growth and quite a bit less cold hardiness. At our wholesale nursery this wonderful shrub has not suffered cold damage down to 5ºF. Lean conditions increase hardiness. Hellstrips, low water garden sections. Hot dry biomes. A great rockrose.
A fantastic low growing Rockrose with superior pink/purple (Pinkle?) flowers for an extended period in May-July. To just 18″ tall it spreads to 3′ wide in average to enriched soil in full sun. The crinkled sage green foliage emits a sweet perfume, especially if you stick your nose right up to it- but mostly it is noticeable on warm days. Its spicy and sweet and adds to the good feelings this very cold hardy selection gives gardeners. One of the last plants to be marauded by deer it makes a great border shrub for rural areas as well. Drought adapted when established, give it one or two good soaks in summer to keep it fresh. Well scaled plant that seldom requires pruning. This selection has survived 0ºF with minor leaf burn and a full recovery by bloom time. Flowers that each last one day come in a weeks long promenade. Rock gardens, hells strips.
Rockrose are famous for the sweet balsam fragrance emitted from their foliage. The chemical ladanum is responsible and the heart shaped thick leaves of this hybrid are drenched with it. This chemical imparts a certain amount of fire retardant. Hot days bring a wave of perfume from Cistus x pagei long after its profuse display of pale pale pink flowers. Its vaguely pink from a distance. Very heavy bloomer. To 5’x 5′ in 5 years. Exceptionally hardy to cold and very very drought tolerant as well. Tolerates subfreezing wind and temperatures near 0ºF with no harm. Excellent low care shrub for rough areas. Full sun and well drained soil. Light summer water to establish. Moderate deer resistance. Excellent shrub for rural areas. In time it develops gnarled trunks with a shredded exterior. Prune if needed AFTER flowering. Rugged, beautiful, fragrant shrub.
