More about Red Cluster Bottlebrush...

Noteworthy Characteristics

Red Cluster is a hardy bottlebrush that can tolerate temperatures down to zero degrees, and is listed to grow in USDA Zones 7a-11. The unusual, eye-catching, bright red flower spikes, which are shaped like a bottle brush appear on and off all year - more in warmer months - and attract hummingbirds and butterflies!


Red Cluster Bottlebrush can be grown as a large shrub or an attractive small tree. As a shrub it lends itself well to hedges and screens, in groupings, or as an accent, corner plant or espalier (flat aginst a wall) in foundation plantings. When "limbed up" to form a small tree, it serves well as a single specimen in foundation plantings and landscape beds or in small groupings in landcape beds. Great for the hummingbird or butterfly garden!


Culture & Care Tips

Prefers a well-drained moist soil rich in organic matter and full to mostly sun. Fertilize with a well-balanced shrub and tree fertilizer in spring, summer and fall in Zones 9 and 10 and just spring and summer in zones further north. When there is extended drought, bottlebrushes will appreciate regular watering. Pruning is not necessary, however the plant responds well to heavy pruning in early spring - when up to 1/3 of the plant can be removed to encourage a more dense plant. Give it a good drink at least an hour prior to doing any hard pruning.
