From Seed to Splendor: Multiplying Your Verbascum boerhavii Collection
The Verbascum boerhavii, also known as the “Nettle-leaved Mullein,” is a captivating biennial with a rich history of medicinal use and a stunning display of bright yellow flower spikes. But what if you want to share this beauty with your garden friends or simply expand your own collection? The good news is, propagation is relatively easy with this hardy plant, and there are multiple methods you can utilize.
The Seed Saga: Starting from Scratch
Verbascum boerhavii is a prolific seed producer, making starting from seed an accessible and rewarding method. Here’s how:
Collect Seeds: After the plant has bloomed, the seed capsules will turn brown and dry. Gently collect these capsules and allow them to dry completely before extracting the seeds.
Direct Sowing: In the fall, gently sow the seeds directly into the ground where you want them to grow. This is the most natural method and allows the plants to establish a strong root system over the winter.
- Starting Indoors: If you have a short growing season, starting your seeds indoors in early spring is a good option. Use seed trays with well-draining potting mix and place them in a sunny location. Thin out seedlings once they have a few true leaves and harden them off before transplanting outdoors.
Dividing for Double the Charm
Verbascum boerhavii readily forms clumps as it matures. Dividing existing plants is an efficient and rewarding way to expand your collection:
Choose the Right Time: Early spring or late summer is ideal for dividing, when the plants are dormant or have finished flowering.
Careful Separation: Dig up the clump and use a sharp, clean knife or spade to carefully separate the plants into individual sections, each with its own root system.
- Replanting: Plant the divisions in well-prepared soil, ensuring the root crown sits at or slightly above ground level. Water them in thoroughly.
A Note on Sustainability
Verbascum boerhavii is a self-sowing plant, meaning it readily spreads from seed. While this can be advantageous for creating a naturalised garden, be mindful of their spread and remove any unwanted seedlings to prevent overpopulation.
Beyond Propagation
Now that you have successfully multiplied your Verbascum boerhavii collection, it’s time to enjoy their beauty! These robust plants prefer well-drained soil in full sun and are relatively pest-free. With proper care and propagation, your Verbascum boerhavii will bring vibrant yellow blossoms to your garden for years to come.
Remember, propagation is a rewarding experience that allows you to share your love of gardening and the joys of growing with others. So get your hands dirty, embrace the process, and watch your Verbascum boerhavii collection flourish!
