1. Canna warscewiczii
I’ve grown these from my own saved seed with very good germination rates. They quickly clump up and flower in their first year from early an sowing (these were sown five months ago in February). Unlike other Canna, I have still not managed to overwinter C. warscewiczii successfully, but no matter when they produce abundant seed which is still viable after at least two years.
2. Agapanthus (unknown species)
I was given this plant by Carolyn Ramsamy last year when we caught up at Hortus Loci for the Perennial Hampton Court Show garden briefing. It’s doing really well having survived the winter and has approx 16 flower buds.
3. Foeniculum vulgare ‘Purpureum’ (bronze fennel)
A regular self-sower since I introduced a single plant into the garden a few years back. I love the delicate frothy foliage and the long tap root makes it an ideal plant for a dry sunny position. I definitely need to use it more in the garden.
4. Cephalaria gigantea (giant scabious)
Grown from seed collected from a local garden (with the Head Gardener’s permission) this is still in a pot whilst I try to work out where to place it. Living up to its name it can reach 2.5m making quite a statement in the border, it’s also good for pollinators.
5. Verbena bonariensis
Now a prolific self-seeder, it’s strange to imagine that just two years ago I wasn’t even sure that it would take in my garden. I don’t mind weeding out the extra plants when you consider that it flowers all summer long and just today has attracted Peacock, Gatekeeper and Cabbage White butterflies.
6. Persicaria orientalis (Kiss me over the garden gate)
Unlike the Verbena this has not been prolific in my garden, preferring it seems to self-seed in pots rather than the ground. This year my tray sown seeds failed so I’m left with just one plant somewhat awkwardly growing out of a pot of Colocasia. I’m still hoping that I can get it to establish in the garden as it quickly makes a tall addition to the back of the border.
