database - SQL recursive query on self referencing table (Oracle)

Question

Lets assume I have this sample data:

| Name     | ID | PARENT_ID |
-----------------------------
| a1       | 1  | null      |
| b2       | 2  | null      |
| c3       | 3  | null      |
| a1.d4    | 4  | 1         |
| a1.e5    | 5  | 1         |
| a1.d4.f6 | 6  | 4         |
| a1.d4.g7 | 7  | 4         |
| a1.e5.h8 | 8  | 5         |
| a2.i9    | 9  | 2         |
| a2.i9.j10| 10 | 9         |

I would like to select all records start from accountId = 1, so the expected result would be:

| Name     | ID | PARENT_NAME | PARENT_ID | 
-------------------------------------------
| a1       | 1  | null        | null      |
| a1.d4    | 4  | a1          | 1         |
| a1.e5    | 5  | a1          | 1         |
| a1.d4.f6 | 6  | a1.d4       | 4         |
| a1.d4.g7 | 7  | a1.d4       | 4         |
| a1.e5.h8 | 8  | a1.e5       | 5         |

I am currently able to make the recursive select, but then I can't access the data from the parent reference, hence I can't return parent_name. The code I'm using is (adapted to the simplistic example):

SELECT id, parent_id, name
FROM tbl 
  START WITH id = 1 
  CONNECT BY PRIOR id = parent_id

What SQL should I be using to the mentioned above retrieval?

Use:

    SELECT t1.id, 
           t1.parent_id, 
           t1.name,
           t2.name AS parent_name,
           t2.id AS parent_id
      FROM tbl t1
 LEFT JOIN tbl t2 ON t2.id = t1.parent_id
START WITH t1.id = 1 
CONNECT BY PRIOR t1.id = t1.parent_id
