Details12-18" tall x 4-6' wide (cutting propagated). The fabulous spring display of creamy yellow flowers and year-round, bright green stems of this spreading shrub make it a standout in the xeric landscape. Originally recommended to me by Colorado gardener, author, garden writer Marsha Tatroe, her enthusiasm for this vigorous, hybrid shrub is well founded. A carefree grower, it lives for decades as a woody groundcover in harsh sites and difficult-to-plant slopes. Combine it with upright growing ornamental grasses and around the base larger shrubs for best effect. This sterile hybrid between C. ardoinii and C. multiflorus was originally discovered at Kew Gardens in England. Here, it was recognized by the Royal Horticultural Society with their Award of Garden Merit. Thia Cytisus has not been observed to reseed in the Intermountain West. (Not for sale to CA, WA or OR.)

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).
