Double the Blooms, Double the Fun: Propagating Morning Iris (Orthrosanthus polystachyus)
The Morning Iris, or Orthrosanthus polystachyus, is a charming Australian native that’s surprisingly easy to propagate. If you’re smitten with its delicate blue-purple blooms and want to expand your garden’s population (or share its beauty with friends), you’re in luck. Let’s delve into the world of propagating this lovely iris, exploring two methods that promise satisfying results.
Method 1: Division – Sharing is Caring (and Easy!)
Division is the most common and straightforward method for propagating Morning Iris. It’s best undertaken in late winter or early spring when the plant is dormant but poised for new growth. Here’s how to divide and conquer:
- Prepare Your Tools: You’ll need a sharp, clean spade or garden knife and a bucket of water to keep the roots moist.
- Carefully Lift the Clump: Gently ease the entire clump of Morning Iris out of the ground, ensuring you dig a wide circle to minimize root damage.
- Divide and Separate: Identify natural divisions within the clump. The rhizomes (thickened stems) will often show clear points of separation. Using your spade or knife, carefully cut through the rhizomes, ensuring each division has a good amount of roots and shoots attached.
- Replant and Water: Replant the divisions at the same depth they were originally growing. Water them in well to settle the soil and encourage establishment.
Method 2: From Seed to Bloom – A Rewarding Journey
While division offers a quicker route to new plants, propagating Morning Iris from seed is an exciting and fulfilling journey. Here’s what you need to know:
- Seed Collection: Morning Iris produces small seed pods after flowering. Allow the pods to dry completely on the plant before collecting them – you’ll know they’re ready when they turn brown and start to split open.
- Sowing the Seed: You can sow the seeds directly into prepared garden beds in spring or autumn, or start them indoors in seed trays filled with a good quality seed-raising mix.
- Patience is Key: Seed-grown plants may take a couple of years to reach flowering size, but the wait is well worth it. Remember to provide consistent watering, especially during dry periods, and a light application of fertilizer once established.
Tips for Success:
- Well-Drained Soil is a Must: Morning Iris thrives in well-drained soil. If your soil is heavy clay, amending it with compost or other organic matter will greatly benefit the plant.
- Sunshine is Your Friend: Choose a sunny or partially shaded location for your Morning Iris. At least 4-6 hours of sunlight is optimal.
- Don’t Be Afraid to Trim: Deadheading spent flower stalks and trimming back any dead or damaged foliage will keep your plants looking their best and encourage more abundant blooming.
Propagating Morning Iris, either by division or seed, is a rewarding endeavor for any gardener. With a little care and attention, you’ll be rewarded with a beautiful display of these charming blue-purple blooms year after year.
