Cut the purple pool noodles into 1-inch thick slices. Make sure to cut evenly to maintain a consistent look.
Take the green PVC pipes and ensure they are clean and dry. These will serve as the stems of your allium flowers.
Begin attaching the pool noodle slices to the top of each PVC pipe using the outdoor adhesive. Apply glue to one side of a noodle slice and press it onto the pipe.
Continue stacking and gluing the slices on top of each other, rotating them as needed to create a spherical shape resembling an allium flower head.
Allow the adhesive to dry completely, ensuring the pool noodle slices are securely attached.
Once dry, place the PVC pipes into your desired location in the garden. You can use garden stakes to provide additional stability if needed.
For a different look, consider using pool noodles in various shades of purple or even mixing in some pink for a more dynamic color palette. You can also experiment with different pipe heights to create a more varied and naturalistic grouping of flowers. If you prefer a more rustic look, wrap the PVC pipes in brown or green twine to mimic natural plant stems and integrate them more seamlessly into a garden with natural elements.
