Crochet Dahlia Flower Pattern | Free Step-by-Step Crochet Tutorial

A crochet dahlia flower brings together a textured centre, layers of pointed petals and shaped green leaves. This illustrated guide follows the construction from the centre outwards, then through the green backing, leaf shaping and stem assembly.

Make a single decorative stem or plan a handmade arrangement with our free crochet flower patterns. For floral projects you can follow from saved charts and written rows, explore our botanical crochet PDF patterns.

Colour and Bouquet Inspiration

Use cream for the centre, lighter blue for the inner petals and darker blue for the outer layers. Changing colour between layers can help show the flower's shape. Pink, lilac or warm neutral shades offer other possibilities.

Let a full dahlia bloom take the main position in a bouquet, then add smaller flowers and foliage around it. The following photographs show other arrangements for colour and composition inspiration.

Materials for a Crochet Dahlia

  • Yarn in cream, light blue, dark blue and green, or your preferred four-colour combination
  • A 2.5 mm or 3.0 mm crochet hook suited to your yarn, with enough usable shaft space to hold the short Tunisian passes
  • A flower rod approximately 40 cm long and 2 mm in diameter
  • Flexible craft wire approximately 0.5 mm in diameter for the leaves
  • A tapestry needle
  • Stitch markers
  • Scissors and wire cutters
  • A small amount of fiberfill
  • Hot glue and a glue gun for assembly

Choose yarn that gives the petals enough firmness to hold their shape. A ply count alone does not establish yarn thickness, so check the fabric made by your chosen yarn and hook.

Skill Level and Gauge

This is an intermediate-to-advanced project combining ordinary crochet, short Tunisian passes, loop-specific rounds and shaped leaves. Familiarity with basic stitches alone will not cover every technique used here.

No fixed gauge or finished measurement is specified. Yarn, hook size and tension will change the flower's size and structure. Practice one petal before working an entire layer.

Written-pattern review note: This is a revised reference draft. The centre has been interpreted as six clusters to match the following six-repeat foundation rounds. The short Tunisian passes and leaf-side insertion points still need practical verification. Use the photographs as construction references, and test the revised steps before relying on them for a complete project.

Stitches and Abbreviations

Ordinary crochet instructions use US terminology.

  • ch: chain
  • st / sts: stitch / stitches
  • ss: slip stitch
  • sc: single crochet
  • hdc: half double crochet
  • dc: double crochet
  • inc: 2 sc in the same stitch
  • sc2tog: single crochet two stitches together
  • FLO: front loop only
  • BLO: back loop only
  • TSS: Tunisian simple stitch
  • Tdc: Tunisian double crochet
  • RetP: return pass
  • sk: skip
  • [number]: foundation or backing stitch count, excluding petal stitches

Special Stitches and Techniques

Two-Double-Crochet Cluster

Into the same space, work two partial double crochets: for each one, yarn over, insert the hook, draw up a loop, then yarn over and draw through two loops. Leave each stitch unfinished. With three loops on the hook after the second partial dc, yarn over and draw through all three to close one cluster.

Single Crochet Decrease

Draw up a loop in each of the next two stitches. Yarn over and draw through the three loops on the hook. This combines two base stitches into one sc.

Tunisian Forward and Return Passes

The petal instructions below distinguish retained-loop Tunisian stitches from ordinary crochet stitches.

  • TSS pickup: Insert into the specified chain back bump or vertical bar, draw up a loop and retain it on the hook.
  • Tdc pickup: Yarn over before inserting into the specified position. Draw up a loop, then draw yarn through the two newest loops. Retain the remaining new loop for the return pass.
  • Standard RetP: With the loops collected, draw yarn through one loop first, then through pairs of loops until one remains.

Complete the return pass before working the ordinary sc, hdc or dc edging that follows. The precise entry positions and edge treatment for these short petal passes still require verification; the general return-pass description alone does not resolve them.

Pattern Notes

  • The petals attach to front loops; the next foundation round uses the corresponding remaining back loops.
  • Work new foundation stitches into the circular base, not into the tops of the projecting petals.
  • Starting chains and joining slip stitches do not count towards the stated foundation totals.
  • Ordinary foundation rounds are joined with 1 ss to the first stitch.
  • Keep cream, light blue and dark blue as colour labels for the flower layers; use green for the backing and leaves.
  • The five sc increase rounds produce foundation counts of 12, 18, 24, 30 and 36 before the backing decreases.

Build the Dahlia Centre and Petal Layers

R1: Centre — Revised Six-Cluster Interpretation

With cream yarn, make a magic ring. Ch 2 and work six two-dc clusters into the ring. Tighten the ring and join to the first cluster. The starting ch 2 does not count as an additional cluster. [6 clusters]

Starting the cream crochet dahlia centre

R2: Six Small Centre Petals

Work in the front loops of R1. For each petal, ch 5. Starting in the second chain from the hook and using chain back bumps, work 1 ss, 1 sc, 1 hdc and 1 sc back towards the centre. Work 1 ss at the petal base, then 1 ss in the next front loop to move to the next anchor. Repeat for six petals.

This separates the four chain stitches from the final base attachment; verify the attachment position when testing the revised centre.

R3: Expand the Foundation

Move to the remaining back loops of R1. Ch 1 and work 2 sc in each of the six base stitches. Join. [12 sc]

R4: Six Short Petals

Work in the front loops of R3. Repeat the following six times:

  1. Ch 7 and secure the upper chain back-bump position with 1 ss.
  2. Pick up six TSS loops along the chain positions and complete RetP.
  3. Skip one edging position, work 4 sc and slip stitch at the petal base.
  4. Work 1 ss in each of the next two base front loops to advance to the next petal.

Review point: The original short-pass wording does not fully identify the top and bottom edge positions. Confirm this petal's return-pass edge treatment before completing the layer.

Fasten off and use the tail to wrap the wire at the leaf base. Cover the wire ends before attaching the leaves to the stem.

Assemble the Leaves and Flower

Prepare the Leaf Branch

Arranging the green leaves into a branch

  1. Wrap the yarn tails around the leaf wires and secure the ends.
  2. Arrange one large leaf and two small leaves as a three-leaf branch. Wrap their wires together with green yarn.
  3. Keep the second large leaf separate to place lower on the flower stem, or arrange all four leaves individually.

Attach the Flower and Wrap the Stem

Blue crochet dahlia with green leaves ready for stem assembly

  1. Position the top of the flower rod in the central opening of the green backing.
  2. Use the backing tail and a small amount of adhesive to secure the flower to the rod. Close the remaining opening around the rod without pulling the flower out of shape.
  3. Wrap green yarn around the rod, starting just beneath the flower.
  4. Attach the leaf branch and remaining large leaf at your preferred heights, wrapping over their wires as you continue down the rod.
  5. Secure the final yarn end and cover the wire tips.
  6. Shape the green sepal points beneath the petals. Secure individual points lightly if needed; they are part of the backing, rather than a separate sepal piece.
