A good time for sowing biennials is the month of July. I am hence sharing here a list of biennial plants featured on this website, many of which are also part of my seed boxes.

Black Hollyhock (Alcea rosea var. nigra) + Angelica (Angelica archangelica) + Korean Angelica (Angelica gigas) + Candle Larkspur (Delphinium elatum) + Foxglove (Digitalis purpurea) + Viper’s Bugloss (Echium vulgare) + Caper Spurge (Euphorbia lathyris) + Fennel (Foeniculum vulgare) + Purple Loosestrife (Lysimachia atropurpurea) + Clary Sage (Salvia sclarea) + Mullein (Verbascum spp.)

Some of the above listed plants may also behave as short lived perennials, e.g. if dead-headed before setting seed. Besides these some annual plants may act as biennials, e.g. if sown in late summer or autumn:

Centaury (Centaurium erythraea) + Cornflower (Centaurea cyanus) + Rocket larkspur (Consolida ajacis) + Black Henbane (Hyoscyamus niger) + Poppy (Papaver somniferum) + Wild Pansy (Viola tricolor)
