Even though biennials have a two year growth cycle, sometimes, if they are started in the mid to late summer and allowed to get a little growth on them, they might bloom the following season. But even if it does take the full two years to get going, they are worth waiting for because they will generally self seed freely and you will have continuous plants coming along year after year. There will be lots to move around your yard or to share with other gardeners.
Canterbury Bells: Companula (cam-pan-U-la) Cups and Saucers –
This bell-flower comes in whites, pinks and blues. It grows from 2-4′ tall and may require staking. Canterbury bells readily self sows. Seeds should be sown during the summer to produce flowering plants the following year. Cups and saucers prefers moist, well-drained soils in partial shade.
Forget-Me-Nots:Myosotis (mi-O-sah-tis) –
Forget-Me-Nots are a low growing plant with clusters of small, beautiful blue flowers which appear in early spring. The plant dies back after freely re-seeding, and the new plants appears late in summer or fall as a small, leafy plant. These plants are reliable bloomers after getting established, and you almost don’t even notice them in the garden, until early spring, when they make a beautiful showing.
Foxglove: Digitalis (dij-i-tal-is) –
The first year, foxgloves will form a dense rosette of leaves. The following late spring/early summer, foxgloves will produce a large terminal raceme (stem) that reaches 2-4′ in height. Each raceme produces numerous tubular 2″ flours that usually come in white, pink or yellow. Seeds are sown in the late summer/early fall for flowering the following year. Foxgloves perform best if planted in partial shade, however they may need staking. Foxglove readily self sows.
Hollyhocks: Alcea (AL-see-uh) –
This is an old time favorite found in cottage gardens, reminding us of long ago. It is an erect, showy plant that grows 2-8′ tall. The 2-4″ single or double blooms range in color from white through yellow, and pink to deep-red and almost black. They bloom over a long period of time and readily self sew. Hollyhocks belong at the back of the garden or along fences and walls. A large clump makes a beautiful accent. Hollyhocks thrive in average to rich, well-drained soils, in full sun or partial shade. Roots go very deep so transplanting is only successful if done when plant is very young.
Money Plant: Lunaria (lun-air-E-a) –
Money plant prefers cool weather, thus will perform best in partial shade. The plant produces fragrant pink or purple flowers on a terminal raceme (stem) that reaches 2-3′ tall during the during. In mid-summer, the dead flower stalks are often removed for use in dried flower arrangements. The outer sheaths on the fruit are removed to expose a silver papery septum for which the plant is named. Often, planing is reserved to the fut flower garden, Money Plant readily self sows.
Sweet William: Dianthus (dI-an-thus) –
Flowers appear in dense terminal clusters that make this a particularly showy species of Dianthus. Seeds usually produce a variety of colors, so division is often necessary to ensure true colors. ?The flowers are sweetly fragrant. Sweet William readily self sows.
