Summary & Analysis of “A Poison Tree” by William Blake

Text of the Poem: A Poison Tree

I was angry with my friend;

I told my wrath, my wrath did end.

I was angry with my foe:

I told it not, my wrath did grow.


And I waterd it in fears,

Night & morning with my tears:

And I sunned it with smiles,

And with soft deceitful wiles.


And it grew both day and night.

Till it bore an apple bright.

And my foe beheld it shine,

And he knew that it was mine.


And into my garden stole,

When the night had veild the pole;

In the morning glad I see;

My foe outstretched beneath the tree.

Introduction to the Poem A Poison Tree

A Poison Tree is a short poem and one of the most appreciated works of William Blake. Initially, this poem was published in his collection of Songs Of Experience in the year 1794. A Poison Tree is a descriptive poem that depicts human emotions and their consequences. This poem was published with the title A Poison Tree in 1830 in the London University Magazine. Although Christian Forbearance was its original title and later on it was changed to reflect better thoughts of the poet.


A Poison Tree is about the hatred and corrupted effects of anger towards others. In the poem, Blake shares his experiences with us that once he was angry with one of his friends and told him about the matter of annoyance. Consequently, the anger vanished away and both became friends again. In contrast, he tells that once he was angry over his enemy but he never told him about the matter, the anger kept growing in his mind against enemy and forced him to keep it hidden from his enemy. He symbolizes anger by a poison tree full of fruits which Blake’s enemy happens to steal and consequently dies.

Structure of the Poem

William Blake’s poem, A Poison Tree, has four stanzas with rhyme scheme AABB and each stanza having four lines. Poet also makes use of end-rhyme to make is full of artistic style.  Each stanza is based on two end-rhymed couplets. As in the first stanza, first and second lines end with rhyming words ‘friend’ and ‘end’ (AA). In the same way third and fourth line end with ‘foe’ and ‘grow’ (BB) that make perfect rhyming (AABB).

The poem is written in trochaic tetrameter catalectic that means that the meter used is the trochee: a stressed syllable followed by an unstressed syllable, e.g. in the line ‘Till it bore an apple bright’ the stresses are as follows:

‘TILL it | BORE an| A pple | BRIGHT’

Trochaic tetrameter catalectic follows as | DUM da | DUM da | DUM da | DUM |

There are four feet in each line, hence tetrameter. But in trochaic tetrameter catalectic, the fourth feet contains single syllable or unstressed syllable is missing as in above line. Trochaic tetrameter catalectic meter gives the poem a clipped, even abrupt feel, which is reinforced by the short sentences and recurrent use of full stops.

Summary of the poem A Poison Tree

Stanza 1

The poet says in first stanza that once he was angry with his one of the friends due to any reason and he told him clearly about it. By doing so, all his anger against his friend vanished away and again they became friends.

In second half of first stanza, poet narrates another experience that once he got angry with his one enemy and did not tell him about it. This time anger stared growing in poet’s mind.

In the first stanza, we come to know that how it is easy to reconcile with a friend if we clear doubts and misunderstandings. However, on the other hand, if we do not talk to someone when we are angry with him; anger and hate will keep growing in our mind against enemy.

Stanza 2

In second stanza, poet elaborates his experience that he watered his anger every day and night in fears of disclosing it to his enemy. He also shed tears because of hate. Here poet wants to tell that he failed to give up his anger that causes him fear and tears. Wrath kept growing in poets mind by day and night because he feared to reveal it to enemy and in this way memory of ill-activity remained alive in his mind.

In the last two lines of second stanza, Blake says that he sunned his anger with smiles and soft deceitful wiles. Here poet symbolizes his anger as a tree which is as growing in his mind as tree grows in light of sun. In last line, poet says that the deceitful tricks (hiding anger) made the tree grow up in poet’s mind.

Stanza 3

In third stanza, poet explains that the tree kept growing day and night and finally one day it became a full grown tree with a bright apple. “Bright Apple” depicts here something which attracts his enemy to eat it. However, deceitful tricks like deceit and hate made this bright apple fully grown and it is harmful for the enemy

Many critics compare this bright apple with the apple of the Heaven that was forbidden for Adam to eat as believed in Christian and Islamic Theology. Adam and Eve were attracted by Satan (Lucifer) to eat the forbidden apple but it caused a disaster in their lives and they were expelled from the Heaven. Here poet wants to tell that like Lucifer, he kept hidden his intentions and kept smile on his face that caused harm to his enemy.

Some critics refer this bright apple to some of written works of Blake which were stolen by one of his friends and caused shame for his friend latter on.

Stanza 4

In last stanza poets tells about the consequences of that bright apple. Like Adam and Eve, the poet’s enemy stole the bright apple from the garden at night and ate it. Later on, in the morning, the poet is happy when he looks at his enemy lying dead under the tree. Here poet compare himself with Satan as Satan was also glad to see Adam and Eve being expelled from Heaven.

The message poet wants to covey is that anger and hatred make one like Satan and when he plans to take revenge for something bad done to him, one forgets the consequences. Morally, poet tells us that we should clear our misunderstanding until they become like a bright apple that can cause harm.

Analysis of A Poison Tree : Critical appreciation

The poem reveals the power of anger if not controlled at initial stage. Anger is an aggressive and dangerous emotion that we all possess as human beings. In the poem, Blake has stated clearly at the start that when we give up our anger, we can escape from drastic consequences of grown up anger. When poet forgives his friend, he saved himself as well his friend from the harm of the hatred.

When poet keep anger in his mind and it keeps growing by different ways elaborated in the poem cause deadly harm to the enemy of the poet. Instead of clearing doubts and grievances he remembered every little thing that he has wrongly done to put him down and harmed him dreadfully.

Blake clearly states that he intentionally did not forgive his enemy, even though he could. If first case, poet did so and saved his friend from the harm but he did not did so in case of enemy.

Poet tries to explain it by a Biblical reference that when Adam and Eve were forbidden to eat apple but Satan urged them to eat that apple that caused them to being expelled from the Heaven. In the same way, here poets states that if he did not save him his enemy, even though he could save. He did the same act as the Satan did in expelling them from the Heaven. Poet passed smile towards his enemy as Satan urged Adam and Eve politely by hiding internal enmity. And finally poet became glad when his enemy was stretched beneath the tree; he also followed Satan who became glad when Adam and Eve were expelled from the Heaven for eating forbidden apple.

The poem ‘A Poison Tree’ is one of the most striking explorations of the corrupting effects of wrath and hatred in English literature. Blake’s portrayal of anger, bitter, and wrath show the deep level of seriousness rampant in the poem. It is also one of William Blake’s miniature masterpieces.
