The namesake flowers on this heat tolerant Australian native bloom nearly year-round and resemble large, crimson (…you guessed it) bottle brushes! Hummingbirds find these distinctive, spiky blooms absolutely irresistible, even though they aren’t the trumpet shape that we typically associate with hummingbird attractors.
Scarlet bottlebrush’s evergreen foliage offers a medium texture and makes a fantastic screen or landscape foundation. This versatile plant can be pruned as a hedge or shaped into a small tree, but when left to its own devices it will form a large, rounded, multi-branching shrub. You may hear some people refer to it as lemon bottlebrush because of the distinctive citrus scent you can smell when its leaves are crushed. Plant them in clear sight, where their unique flowers and the constant hummingbird activity can be enjoyed.
