Perennials

Lupinus 'Gallery' mixed – perennial plants

Perennials: hardy flowering plants for borders, parks and pots

Perennials return every year and, with flowers, foliage and structure, create long-lasting planting. Besides its own groups astilbe, echinacea, daylily, hosta and phlox, Holland Bulb Market supplies a wide range of other perennials, such as Aquilegia, Delphinium, Digitalis, Geranium, Kniphofia, Liatris, Lupinus, Sedum and Tricyrtis. With the right combination, a border flowers from April into October. The plants are supplied as rhizomes or planting stock for gardens, pots and public planting.

Uses

Borders: a succession of flowers from spring to autumn, complemented by bulbs such as allium.
Public planting and projects: durable, low-maintenance planting for parks, business parks and road verges.
Pollinator-friendly planting: species such as Liatris, Sedum and Geranium are rich in nectar.
Retail: rhizomes in consumer packs and pot plants for spring and summer sales.

Professional cultivation: perennials in pots

Most perennials are potted in spring in 1–3 litre pots with the crown at or just below the surface. Grow them cool and light, in a cold greenhouse or outdoors on a container field, and use well-drained potting soil. This way they can be delivered in spring and summer as flowering or ready-to-sell pot plants.

Delphinium, Lupinus and Digitalis need strong root development before flowering; plant them in good time. Read more about professional growing.
