<P> The silk floss tree is cultivated mostly for ornamental purposes . Outside of private gardens around the world , it is often planted along urban streets in subtropical areas such as in Spain , South Africa , Australia , northern New Zealand and the southern USA , although its prickled trunks and limbs require safety buffer zones , especially around the trunks , in order to protect people and domesticated animals from its prickles . Ceiba speciosa is added to some versions of the hallucinogenic drink Ayahuasca . </P>
