This bushy shrub grows in entangled thickets, which are a refuge to birds and chamois that are in search of coolness and quiet. It is a pioneer and not afraid of settling in poor, steep terrains. Its strong roots mean it can latch on where everything else slides. Its flexibility means avalanches slide over it as it bends under the weight of the snow. The male catkins dangle when they are mature showing the pale yellow of their flowers. The female flowers will bear characteristic fruit like small pinecones that are first green, and then brown that persist all year round.
