About this box

In the rush for instant gratification with annuals, it's easy to overlook the plants that truly define the cottage garden: biennials. These are the flowers that fill the "June Gap" — the lull between the last tulips of spring and the first roses of summer — with scent and height exactly when the garden needs it most.

Sown in the warmth of June or July, biennials establish strong roots and leafy rosettes before winter, then explode into majestic bloom early the following year. From the dramatic near-black spires of Hollyhock 'Nigra' to the evening perfume of Sweet Rocket, this box contains eight essential ingredients for a timeless cottage garden display.

Understanding Biennials

Year 1 (June–July sowing): The plant focuses entirely on building a strong root system and rosette of leaves — no flowers this year. Year 2 (spring–summer): It re-emerges from winter, sends up tall flower spikes, blooms spectacularly, sets seed, and completes its cycle.

Most plants in this box are prolific self-seeders — establish them once and they return year after year for free.

The Summer Sowing Method

Sow in June or July in a nursery bed or pots outdoors — no special equipment needed. Keep watered through the summer heat. In September or October, move young plants to their final flowering positions, such as into the beds where tulips are planted, and let them settle in before winter. Full instructions are printed on every packet.

Arrives in signature eco-friendly packaging — a thoughtful gift for the gardener who likes to plan ahead.

Happy Hesperis

I've never grown Hesperis (sweet rocket) until this year, but Melanie's seeds were so successful and prolific, that I now have beautiful flowers wafting their amazing aroma around my garden...plus our honey bees are so happy 🐝 In fact lots of pollinators are visiting!

Excellent!

I bought a variety of seeds to sow now for next summer, and they are all doing really well so far! Re- potted them this week so watching carefully and enjoying the process. I’ve also bought some vegetable seeds which are doing really well.

Bishy Barnaby’s Cottage Garden have been excellent -beautiful packaging, prompt delivery, great customer service, and I love the emails that guide you with what to sow and when, really informative.
I wouldn’t want to get my seeds from anywhere else now.

Hollyhock Nigra Seeds

The Hollyhock Seeds arrived promptly last week nicely packaged. The Seeds were sown the next day and as usual with Bishby Barnabee Seeds the healthy little seedlings emerged in a couple of days and are growing nicely into sturdy seedlings - thank you.

I didn’t realise how beautiful these flowers are! I grew them for the first time this year. I’ve started the next batch off for next year’s flowers. Germination excellent and I’m sure the flowers will be equally good. Already looking forward to seeing them!
