The dry and sunny autumnal weather has been perfect for collecting seeds for next year. I never have the right containers (note to self- keep more old plastic food containers) but end up with an odd assortment on the windowsill. The seedpods or seeds must be completely dry before I store them, in labelled envelopes, in a water-tight container at the bottom of the fridge. Beware- some pods, as they dry, suddenly uncurl dramatically firing seeds out of the labelled container.
I still remember going into my 80-year old Auntie Margery’s dark walk-in cupboard in her sitting room. The cupboard was full to bursting point of “stuff”- old envelopes, newspapers, gardening magazines stacked up on the floor, vases and a large number of carefully labelled plastic margarine pots full of seeds for planting the following year, including beans and peas. I put my hand on the shelf and there was a snap. I emerged with a plastic mouse trap attached to my fore-finger-no mice in my fridge.
When to stop deadheading?
I have to decide when to stop dead-heading. Deadheading encourages plants to continue to flower, but some seedheads may be wonderfully decorative in their own right and I want seeds for next year. Cosmos are still flowering so I am continuing to deadhead. Nicotiana glutinosa was a success with small coppery flowers that complemented the brickwork, but the flowers are over and I have collected seeds. I have also collected seeds from plants such as allium, lunaria (honesty) and scabious. The nasturtiums are looking wonderful tickling the belly of my sheep- but no seeds yet as I planted them rather late.
Eryngium giganteum (Miss Wilmott’s ghost) did look wonderfully structural in the gravel bed, but it is a biennial and now was grey and sad dominating the small space. In a larger bed I might have left it but I have removed it (wearing protective gloves as the spines are so unfriendly), collected seeds and will keep the plant for Christmas decorations. It will look wonderful with a spray of silver paint. The oval seed pods of honesty also make great decorations if one strips off the outer cover leaving a fragile silvery oval pod. I will leave that fun activity for the grandchildren.
